Non-ionizing radiation includes the spectrum of ultraviolet (UV), visible light, infrared (IR), microwave (MW), radio frequency (RF), and extremely low frequency (ELF). Lasers commonly operate in the UV, visible, and IR frequencies." Radiation Therapy- National Cancer Institute http://www.cancer.gov/publications/patient-education/radiationttherapy.pdf "Radiation therapy (also called radiotherapy) is a cancer treatment that uses high doses of radiation to kill cancer cells and stop them from spreading. At low doses, radiation is used as an x-ray to see inside your body and take pictures, such as x-rays of your teeth or broken bones. Radiation used in cancer treatment works in much the same way, except that it is given at higher doses." How Does Nuclear Radiation Harm the Body? http://www.livescience.com/13250-radiation-health-effects-japan-nuclear-reactor-cancer.html "There's been some reported evidence that radioactive iodine and cesium are being released into the environment from the malfunctioning nuclear reactors in Japan, said Kathryn Higley, director of the Oregon State University department of nuclear engineering and radiation health physics." ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!

Scientist Can Now See What Radiation Does To DNA
Scientists have suspected ionizing radiation can cause cancer. Now, experiments conducted in England have demonstrated the damage it inflicts on DNA. According to UPI, the findings may allow doctors to identify tumors caused by radiation. In a study published in the journal Nature Communications, scientists showed the effects of gamma rays, X-rays and radioactive particles on DNA, deciphering patterns they think will help differentiate between spontaneous and radiation-caused tumors. For the study, the researchers looked for mutational signatures in 12 cancer patients with radiation-associated second malignancies, and compared their tumors to 319 from patients not exposed to radiation. The researchers found two mutational signatures they link to radiation. While one causes small deletions of DNA bases, the other -- called a balanced inversion -- includes two cuts to DNA, with the middle piece spinning around and rejoining in the opposite direction. The researchers say these mutations--particularly balanced inversions, which do not happen naturally in the body--increase the potential for cancer to develop. http://www.upi.com/Health_News/2016/09/13/DNA-damage-cancer-caused-by-ionizing-radiation-identified/5151473765849/ http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

What is ionizing radiation?
Ionizing radiation is any form of radiation with enough energy to break off electrons from atoms (that is, to ionize the atoms). This radiation can break the chemical bonds in molecules, including DNA molecules, thereby disturbing their normal functioning. X-rays and gamma rays are the only common forms of radiation with sufficient energy to penetrate and damage body tissue below the surface of the skin. Among the many sources of ionizing radiation are traditional X-rays, computed tomography (CT) scans, fluoroscopy, and other medical radiological procedures. Credit: CDC

How UV Causes Cancer and Aging
UV at ground level is non-ionizing but it damages DNA and causes photoaging - how? Also, it turns out glass doesn't block all UV (specifically UVA passes through). This is something I learned filming with the UV camera inside. Special thanks to Dr. Hayley Golbach, @hayleysgold on twitter https://twitter.com/hayleysgold Ultraviolet light causes damage to DNA, leads to cancer and photoaging: age spots and wrinkles. I was curious about this because UV is technically non-ionizing. A photon of UV doesn't have enough energy to strip an electron off atoms or molecules. However it does have enough energy to trigger photo-chemical reactions. For example, it causes pyrimidine dimers - the unauthorized covalent bonding of adjacent thymine or cytosine bases in our DNA. If these spots are not properly repaired, they may lead to mutations and cancer. Photoaging is typically the result of degradation of collagen and elastin fibers - scaffolding that supports the skin. This leads to wrinkles and saggy-looking skin.

Is WiFi Safe?
You've probably heard that wireless internet (WiFi) is dangerous. But is it true? Lauren breaks it down. Learn more at HowStuffWorks.com: http://computer.howstuffworks.com/wireless-network1.htm Share on Facebook: Share on Twitter: Subscribe: http://goo.gl/ZYI7Gt Visit our site: http://www.brainstuffshow.com Are you there BrainStuff? It’s me, Lauren. Do you ever think about how with wireless internet floating around us that we’re all just wading through gigabytes of HTML, mp3s, jpegs, first-person shooters, and entire videos… like this one? Even if you don’t have a router and avoid the library and your local coffee shop, WiFi is everywhere. So your next question might be whether all that WiFi is safe or not. First, the term “WiFi” just means “a wireless network,” not “wireless fidelity”. Common misconception. These wireless networks translate data into radio signals and then transmit and receive those signals via antennas. So… WiFi is made of radio waves. These are part of the broad range of frequencies that make up the electromagnetic spectrum. We know that some radiation on that spectrum -- like gamma rays, X-rays or high-frequency ultraviolet light -- can be dangerous. These waves are known as ionizing radiation. They’re so high in energy that they can break apart atoms and damage our DNA. But the non-ionizing wavelengths are too low in energy to ionize atoms or molecules. Since radio waves (like WiFi) are non-ionising, they tend to be safe. The intensity of a WiFi signal is rather low. WiFi is most often transmitted at a frequency of 2.4 gigahertz, about the same as most microwave ovens. For comparison, a light bulb emits non-ionizing radiation up to 400 nanometers, which converts to 749,481 gigahertz. That makes light bulbs over 62,000 times stronger than WiFi. Wireless network routers also broadcast further distances than microwave ovens, which is important, because every time you double the distance of a radio wave you only get a quarter of its energy. That’s the “Inverse Square Law of Physics!” Which means WiFi’s intensity drops off sharply the further you get from a device emitting it. Despite WiFi being broadcast at this safe frequency, there are some controversial health concerns associated with the radiation it emits. And while there is no definitive link, the World Health Organization (W.H.O.) does recognize that some studies show preliminary connections between these types of radiation and human illness. They categorize it a Class 2B Carcinogen: Something possibly carcinogenic in humans at given exposures. But your actual wireless internet connection doesn’t seem to be harmful. And if you’re still concerned… your other option is to wrap yourself up in aluminium foil to keep a few of these frequencies at bay. ...No, really. Aluminum foil creates a sort of Faraday cage, which disrupts electromagnetic signals.

The effects of radiation on our health
Our body is made of billions of cells which are arranged to form organs. Approximately one and a half metres of DNA are stored in each cell. DNA undergoes permanent attacks and there a numerous aggressive agents. The following can be mentioned: solvents and pesticides, combustion smoke, viral aggressions, ultraviolet radiation, ionising radiation. All molecules can be affected by radiation, but it is when DNA is impacted that there are the greatest consequences for cellular operation.

What Are the Long-Term Effects of Exposure to Radiation?
http://www.balancedhealthtoday.com/xeneplex.html http://www.balancedhealthtoday.com/store/xeneplex.html The term radiation refers to the way that energy travels from one place to another. There are two main types of radiation, non-ionizing radiation, which does not cause damage to the body and ionizing radiation, which has the ability to penetrate cells and cause chemical changes. Ionizing radiation includes some forms of electromagnetic radiation, including gamma rays, X-rays and ultraviolet rays as well as alpha and beta particles emitted by radioactive materials. Background radiation is the radiation in the environment that people are continually exposed to from isotopes in the soil to cosmic rays from the solar system. Exposure to additional radiation, specifically that created by humans, is the radiation of concern as it can result in permanent and long-term damage. Cancer The Environmental Protection Agency reports that the most common long-term effect of radiation exposure is cancer. The most common cancer to occur due to radiation exposure is leukemia, according to the American Cancer Society. Leukemia is cancer that begins in the tissues that form the blood, which is contained in the bone marrow. Bone marrow, along with the thyroid gland is very susceptible to damage from radiation. There are other cancers that can arise from radiation exposure, including breast cancer and lung cancer. These cancers however take much longer to develop, usually 10 to 15 years, than the leukemia which usually develops within two years of the exposure as reported by the American Cancer Society. Genetic Mutations Radiation damages DNA, deoxyribose nucleic acid, which is the chemical that carries the information to instruct cells what to do. By damaging the DNA, the radiation can induce cancer. DNA is also the information that is passed on from mother and father to their child. It is what determines what the child will look like as well as his future susceptibility to diseases. The damage to the DNA can result in genetic mutations, which are alterations to genes contained in the DNA. These mutations are then passed along to the children and can result in a variety of disorders, including an increased risk for cancer. Sterility Radiation can damage the reproductive organs and cause temporary or even permanent sterility. Patients who undergo radiation treatments involving the pelvic region are at risk of permanent infertility. Whether sterility results from the radiation is influenced by the amount of radiation and the age of the person exposed, according to the National Cancer Institute. http://www.balancedhealthtoday.com/store http://balancedhealthtoday.com/products.html

5 Ways Your Cell Phone Can HURT You
We count down the Top 5 REAL dangers of cell phone use that can actually kill you! It sounds like clickbait, but NO- your cell phone is actually MUCH more dangerous that you might think! A great article that links to 44 different studies that show a relationship between cellphone usage and cancerous brain tumors http://www.greenmedinfo.com/blog/44-reasons-cell-phones-can-cause-cancer The most recent cell phone / cancer study from the US Department of Health and Human Services https://ntp.niehs.nih.gov/results/areas/cellphones/ Bacteria A London University study found that the average cell phone carries 18x more bacteria than a toilet handle. These bacteria can cause anything from minor problems like colds and flus-to more severe skin infections from staphylococcus and streptococcus bacteria. This includes the very dangerous MRSA infection. MRSA has been dubbed the "super bug" because it is resistant to most conventional antibiotic treatments. And yes, you can catch MRSA just from talking on your phone. Punctured Batteries When most people drop their cell phone, they worry about breaking their screen. However, the true hazard in any cell phone drop or impact is damaging the dangerous lithium ion battery inside. If a cell phone battery is punctured, it can cause a chemical reaction so intense that the resulting fire can actually burn through metal. Talking While Driving Now, at first this one seems obvious. Of course no one should talk on a cell phone while driving. However, most of us assume that it's completely safe to drive and talk as long as a hands-free device is used. After all, both hands are on the wheel and our attention is focused on the road. Well, unfortunately it turn out that even talking using a hands free device is still very dangerous. A study by the University of Sussex found that drivers talking on a cell phone using a hands free device could be just as distracted, and just as dangerous, as if they were holding the phone up to their ear. Researchers found that when people talk on the phone, they tend to let their imaginations run wild, sometimes thinking about the topic being discussed or even imagining the expression on the face of the person they're talking to. The University study concluded that there simply IS no way to safely talk on a cell phone while driving, not even hands free. Random Explosions & Fires Now, even if your cell phone is not dropped or damaged in any way, there is still a risk that the battery could just randomly explode or burst into flames. It all comes down to the fact that cell phones contain lithium ion batteries, and these batteries are just dangerous by nature. Lithium ion batteries can short circuit easily and contain dangerous and highly flammable chemicals. Despite what you might have heard, the phenomenon of cell phones exploding or bursting into flames doesn't just occur in cheap cell phones either. Cases have been documented involving some of the most expensive phones on the market. In fact, the Samsung Note 7 actually had to be recalled after a shocking number of spontaneous fires. Brain Tumors To put it simply, when you're using a cell phone to talk, you are holding a high-powered microwave transmitter against your head. Obviously, that doesn't sound like a great idea. But the connection between cell phones and brain tumors is a hotly debated issue. Cell phones produce non-ionizing radiation, which is radiation that does not affect cells on an atomic level. So critics argue that cell radiation therefore cannot possibly cause Cancer. However recent evidence shows otherwise. Recent scientific studies have found a clear connection between long term cell phone use and an increase in dangerous glioma brain tumors. The Interphone study, one of the biggest cell phone studies of all time found that people who had used cell phones for over 10 years were almost twice as likely to have glioma brain tumors. The study also found that tumors were more likely to occur on the side of the head most used for calling. The interesting thing about this is that the Interphone study was actually funded by the mobile phone industry in an attempt to prove that cell phones did NOT cause brain tumors. Numerous recent studies have shown even more conclusive proof that cell phone radiation increases the risk of cancerous tumors. A more recent Swedish study shows that people who used cell phones more than 25 years were 3 times as likely to develop brain tumors. Furthermore, multiple studies have shown an increase in cancerous tumors near where people hold their cell phone. And a study by the US Department of Health and Human Services has conclusively proven that the type of radiation used by cellphones causes cancer in lab rats. The World Health Organization has declared cell phone radiation a type 2B cancer risk.

Radiation Exposure ,Radiation safety- Everything You Need To Know - Dr. Nabil Ebraheim
Dr. Ebraheim’s educational animated video demonstrates how radiation affects the body, the different types of radiology procedures, and safety recommendations. X-rays ionize human tissue and deposit energy that can cause harmful changes within the body (break the DNA chain). There is a cancer risk from X-rays. The dose of radiation is cumulative. X-rays are considered for carcinogen list. The government is attempting to avoid the use of unnecessary CT scans and x-rays to avoid unnecessary exposure to radiation. This highlights the cancer risk. Doctors need to pay close attention to the risks involved with the use of x-rays. The cancer risk associated with radiation exposure is documented in cases of atomic bomb survivors. The risk for medical uses is controversial and usually played down by physicians. Radiation at a high level is carcinogenic. The level of radiation from x-ray exposure is low. The effects of low-level radiation is not known. What is the safe radiation level? The safe level is not known. It is known that CT scans, fluoroscopy, mammography and x-rays expose the public to high levels of radiation especially in young females. The risk of exposure should balance the medical benefit. Optimize radiation doses by exposing the patient only to enough radiation to get a clear image. There is a growing concern about the risk associated with giving patient large doses of radiation. The use of CT scans has increased recently in adults and children possibly exposing the patient to an unnecessarily high dose of radiation. CT scan is the method often used to diagnose cancer, diseases fractures and it exposes the patient to a much larger does of radiation than x-rays. Radiation from CT scan of the pelvis equals the same amount as 100 chest x-rays. Children are ten times more sensitive to radiation than adults. 3-4 million children receive CT scans and about 1,500 of them will develop cancer two decades later. Children should not be given an adult dose of radiation. Radiation dose limits: CT scan of the pelvis has the highest level of exposure to the skin, marrow and gonads. Use mini fluoroscopy C-arm whenever possible. Fluoroscopy emits a lot of radiation. The closer the extremity is to the radiation source, the higher the dose of radiation the patient receives. When the distance from the beam increases, the dose of radiation is less. Attempt to decrease exposure time. Radiation intensity follows the inverse square law. It is all about distance. If the intensity of radiation at 1 meter from the source is 100 mR/hr then the intensity of radiation at 2 meters from the source is ¼ or 25 mR/hr in same unit area. At 3 meters from the source, the intensity of radiation is 1/9 the original or 11.1 mR/hr. Units of radiation (radiation nomenclature) •Roentgen: unit of radiation exposure in air. •Rad: energy absorbed per gram of tissue. •Rem: biological effect of a rad. There is less exposure to the physician when imaging a smaller body part. Larger body parts create an increased exposure to the physician when imaging a patient with C-arm. Do not be in the direct path of the radiation beam. Protection: •Monitoring: a dosimeter badge only records how much radiation you have received. It does not protect you from exposure to radiation. •Shielding: lead gowns and aprons work to stop exposure to fluoroscopy radiation. Lead aprons attenuate scattered radiation by about 95%. •Position Rapidly dividing cells are most sensitive to radiation exposure: sperms, lymphocytes, small intestine, and stomach. Radiation damage seldom appears at the time of radiation. The first effects of radiation damage is usually seen as a drop in the white blood cell count. The first external sign of damage is seen as a skin burn. Studies suggest that people who use fluoroscopy extensively have a higher rate of cataracts. Early effects or radiation exposure: •Death •Hematological depression •Chromosome aberration •Skin erythema •Epilation. Team exposure to radiation •Direct beam 4,000 mrem/min •Surgeon (1 ft.): 20 mrem/min whole body •First assist (2 ft.): 6 mrem/min whole body •No exposure (5 ft.) at scrub or anesthesiologist. •6 feet is safe.

Effects of Ionizing Radiation
http://www.balancedhealthtoday.com http://www.balancedhealthtoday.com/xeneplex.html Some of the ultraviolet (UV) radiation from the sun is considered ionizing radiation, and provides a starting point in considering its effects. Sunlight UV is important in producing vitamin D in humans, but too much exposure produces sunburn and, potentially, skin cancer. Skin tissue is damaged, and that damage to DNA may not be repaired properly, so that over time, cancer develops and may be fatal. Adaptation from repeated low exposure can decrease vulnerability. But exposure to sunlight is quite properly sought after in moderation, and not widely feared. Our knowledge of the effects of shorter-wavelength ionizing radiation from atomic nuclei derives primarily from groups of people who have received high doses. The main difference from UV radiation is that gamma and X-rays can penetrate the skin. The risk associated with large doses of this ionizing radiation is relatively well established. However, the effects, and any risks associated with doses under about 200 mSv, are less obvious because of the large underlying incidence of cancer caused by other factors. Benefits of lower doses have long been recognised, though radiation protection standards assume that any dose of radiation, no matter how small, involves a possible risk to human health. However, available scientific evidence does not indicate any cancer risk or immediate effects at doses below 100 mSv per year. At low levels of exposure, the body's natural mechanisms repair radiation damage to cells soon after it occurs (see following section on low-level radiation). However, high-level irradiation impairs those systems and is harmful. Dose rate is as important as overall dose. http://www.balancedhealthtoday.com/store http://www.balancedhealthtoday.com/store/xeneplex.html

Radiation Exposure and Cancer Part 2
http://www.emfnews.org/qlinks.html http://www.emfnews.org/earthcalm_emf_protection.html http://www.emfnews.org/store/home-cell-phone-and-mobile-tower-radiation-meters.html Ionizing radiation Ionizing radiation has enough energy to knock electrons off of atoms or molecules. This is called ionization. Ionized molecules are unstable and quickly undergo chemical changes. If ionizing radiation passes through a cell in the body, it can lead to mutations (changes) in the cell's DNA, the part of the cell that contains its genes (blueprints). This could contribute to cancer, or to the death of the cell. The amount of damage in the cell is related to the dose of radiation it receives. The damage takes place in only a fraction of a second, but other changes such as the beginning of cancer may take years to develop. Types of ionizing radiation include x-rays, gamma rays, some high-energy UV rays, and particles given off by radioactive materials such as alpha particles and protons. These forms of radiation have different energy levels and can penetrate cells to different extents, but all are capable of causing ionization. Does ionizing radiation cause cancer? Ionizing radiation is a proven human carcinogen (cancer causing agent). The evidence for this comes from many different sources, including studies of atomic bomb survivors in Japan, people exposed during the Chernobyl nuclear accident, people treated with high doses of radiation for cancer and other conditions, and people exposed to high levels of radiation at work, such as uranium miners. Most studies on radiation and cancer risk have looked at people exposed to very high doses of radiation in the settings above. It is harder to measure the much smaller increase in cancer risk that might come from much lower levels of radiation exposure. http://www.emfnews.org/articles/ http://www.emfnews.org/products.html http://www.emfnews.org/store/home-cell-phone-and-mobile-tower-radiation-meters.html

Cell Phone Use Causes Cancer?
Mobile phones use radiofrequency waves for communication. These are non-ionizing radiation. This is an era of technology where smartphones have become an integral part of our lives. While initially intended for easy communication, over the years various features have been incorporated into the smartphones. This has increased our dependency on them exponentially; to the extent that most of us are now addicted to them.

http://www.emfnews.org/Car-Radiation-Cell-Phones-Faraday-Cage-and-Cancer.html http://www.emfnews.org/howitworkschips.html http://www.emfnews.org/home_protection.html Types of radiation Radiation exists across a spectrum from very high-energy (high-frequency) radiation to very low-energy (low-frequency) radiation. This is sometimes referred to as the electromagnetic spectrum. From highest to lowest energy, the main forms of radiation are: • Gamma rays • X-rays • Ultraviolet (UV) rays • Visible light • Infrared rays • Microwaves • Radiofrequency (radio) waves • Extremely low-frequency (ELF) radiation An important distinction that affects the health risks from radiation is whether the energy is ionizing or non-ionizing. Ionizing radiation is high-frequency radiation that has enough energy to remove an electron from (ionize) an atom or molecule. Ionizing radiation has enough energy to damage the DNA in cells, which in turn may lead to cancer. Gamma rays, x-rays, some high-energy UV rays, and some sub-atomic particles such as alpha particles and protons are forms of ionizing radiation. Non-ionizing radiation is low-frequency radiation that does not have enough energy to remove electrons or directly damage DNA. Low-energy UV rays, visible light, infrared rays, microwaves, and radio waves are all forms of non-ionizing radiation. Aside from UV rays, these types of radiation are not known to increase cancer risk. It is important to understand the difference between these types of radiation. For example, the non-ionizing radiation given off by a cell phone or a television screen is not the same as the ionizing radiation you might get from x-rays taken in the hospital. http://www.emfnews.org/articles/ http://www.emfnews.org/products.html http://www.emfnews.org/store/home-cell-phone-and-mobile-tower-radiation-meters.html

RESTRICTIONS: Broadcast: NO USE JAPAN, NO USE TAIWAN Digital: NO USE JAPAN, NO USE TAIWAN Two new studies have found a correlation between cell phone radiation and cancer in lab rats. Smartphones emit non-ionizing radiation, measured in radio-frequency, RF, energy. It's accepted high doses of ionizing radiation, such as X-rays, CT scans and nuclear power plants cause cancer, according to Scientific American. However, it's still unclear if long-term exposure to non-ionizing radiation can cause cancer. Researchers from the U.S. National Toxicology Program tested 3,000 rats and mice of both sexes for two years, while European scientists at the Ramazzini Institute in Italy studied 2,500 rats from fetal stage to death. The studies found that prolonged exposure to even low levels of RF radiation cause male rats to develop rare heart tumors called schwannoma, which affects a neuron called a Schwann cell. In the Ramazzini study, researchers also found a weaker link between RF exposure and glial cell cancer in the brain of female rats. RUNDOWN SHOWS: 1. RF radiation causing cancers in lab rats 2.

It is harder to measure the much smaller increase in cancer risk that might come from much lower levels of radiation exposure. Most studies have not been able to detect an increased risk of cancer among people exposed to low levels of radiation. For example, people living at high altitudes, who are exposed to more natural background radiation from cosmic rays than people living at sea level, do not have noticeably higher cancer rates. Still, most scientists and regulatory agencies agree that even small doses of ionizing radiation increase cancer risk, although by a very small amount. In general, the risk of cancer from radiation exposure increases as the dose of radiation increases. Likewise, the lower the exposure is, the smaller the increase in risk. But there is no threshold below which ionizing radiation is thought to be totally safe. (American Cancer Society) Choose AOX Your natural choice www.aox.com.sg

How to Understand Cellphone Radiation & Cancer Risk
Watch more Cancer & Disease Prevention videos: http://www.howcast.com/videos/476840-How-to-Understand-Cellphone-Radiation-and-Cancer-Risk Step 1: Understand cellphone radiation Know what "cellphone radiation" is. Cellphones emit radiofrequency energy, a form of non-ionizing radiation. Ionizing radiation, the kind produced by X-ray machines, has been linked to cancer; nonionizing radiation has not. Step 2: Understand a research finding Understand the classification of the International Agency for Research on Cancer, which evaluates environmental and lifestyle factors for possible links to cancer. The I.A.R.C. classifies cellphones as a "possible" carcinogen, meaning it's not certain whether they pose a cancer risk. Tip The International Agency for Research on Cancer also lists coffee and pickled vegetables as possible carcinogens. Step 3: Understand the confusion Understand why the I.A.R.C. classification is confusing. Some studies into possible links between cellphones and cancer have found a higher risk of brain tumors, while others have found a lower risk. Some scientists point out that cellphones have been in use for years with no subsequent increase in brain tumors; others say there hasn't been enough time to determine the effect on younger generations who began using cellphones in childhood. Step 4: Play it safe Play it safe by reducing your exposure to cellphone radiation. Use speakerphone or a wired earpiece -- a ferrite bead will lower your exposure even further. Also limit the time you're on your cellphone while walking and when you have a weak signal; cellphones emit more radiation when they're in motion or far away from a cell tower. Tip Avoid wireless earpieces, which emit radiation right at your ear, albeit at lower levels. Step 5: Stay tuned Stay tuned to new research -- the jury is still out on cellphone radiation and cancer risk. In the meantime, it wouldn't hurt to talk less on your cellphone and send text messages whenever possible. Did You Know? 85 percent of Americans 18 and older own a cellphone.

Empowering You to Manage Risk from Cancer Causing Radiation
Cancer is a global crisis. This video provides brief overview of the hidden dangers of ionizing radiation. Cumulative exposure to ionizing radiation is known to cause DNA mutations that causes cancer and comes in many different forms 1) Medical: Excessive radiation due to accidental or uncontrolled doses during x-rays, CT scans, etc., or therapeutic procedures, causes tens of thousands of future cancers annually according to NIH and NCI. Hidden danger for patients and Healthcare professionals alike. 2) Cosmic-background radiation- Cumulative lifetime exposure are danger to occupational safety workers and the general public alike specially to cancer survivors who have gone through radiation therapy treatments; Radiation doses received by pilots, flight attendants and passengers are often greater than those received by radiation workers in the heavily regulated nuclear industry. Medical research has documented a significant correlation between overexposure to cosmic radiation and certain types of cancer. The dose of radiation at the cruising attitude of jetliners is between 60 and 200 times greater than at sea level. 3) Nuclear waste and accidents: Fukushima radiation pollution could cause up to 400,000 added cancer cases among those living within 200 km of the reactor, with " reports of signiificant radiation ... even south of Tokyo". Scientist estimating that Chernobyl had killed 1,400,00 people. Products: Calculates total cumulative radiation exposure and estimates cancer risk over a person's lifetime.

Risk of Ionizing Radiation Exposure to Children
http://balancedhealthtoday.com/buy/xeneplex-for-chemical-sensitivities-glutathione-detoxification-and-organic-coffee-cleanse/ Call Now 1(888)277-4980 Email support@balancedhealthtoday.com Exposure of children to ionizing radiation most commonly is from the environment, chiefly through cosmic rays and radon, or from medical technology. Medical radiation exposure occurs during diagnosis, therapy, and dental radiography. More is known about the biological effects of exposure to ionizing radiation than to nonionizing radiation from microwaves, radiowaves, and the electrical fields of other electrical appliances. This review applies only to sources of ionizing radiation and does not include the potential risks of indoor radon. The effects on children of ionizing radiation have been studied from war activities and environmental accidents. Projections are made from that data to help pediatricians evaluate risk from radiation when ordering radiographs. Epidemiologic studies have shown that persons exposed to high levels of ionizing radiation have an increased risk of cancer, particularly leukemia, and later in life, breast and thyroid cancer.1 In addition, some epidemiologic studies have found that radiation exposure during childhood carries a higher risk of cancer than exposure at other ages.However, it should be noted that these reports studied exposures at relatively high doses (such as those seen at Hiroshima and Nagasaki in Japan). Therefore, the risks of developing cancer from childhood exposure to low levels of radiation from diagnostic x-ray examinations are not well-quantified but are probably very small.The Figure shows the measurements used in determining radiation exposure. LEUKEMIA Studies of atomic bomb survivors showed the risk of mortality from leukemia to be elevated at doses above 0.4 Gray (40 rad), with the excess relative risk ranging from 4.2 to 5.2 per Sievert (100 rem). The risk of leukemia was also found to be elevated (RR = 1.9) in adult populations exposed to x-rays for treatment of ankylosing spondylitis at an average dose of 3.2 Gray (320 rad). Similar risk ratios have been found in patients treated with high doses of radiotherapy for cancer.The risk of leukemia may be higher in children exposed to diagnostic radiation in utero than in unexposed children. In a study of childhood cancer mortality, Monson and MacMahon found that children exposed prenatally to diagnostic x-rays had a 1.5 times higher risk of dying of leukemia than unexposed children. However, other similar studies of prenatal radiation have not found the risk of leukemia to be higher than that associated with childhood exposure. BREAST CANCER Epidemiologic studies indicate that the risk of breast cancer is increased in women who were exposed to high levels of radiation during childhood. Breast cancer rates were higher among female atomic bomb survivors who were 10 to 19 years of age when exposed to the bomb than among those who were older at that time.The excess relative risks found in this study were 2.42 per Sievert for women exposed between 10 and 19 years of age, 1.25 per Sievert (100 rem) for women aged 20 to 39 years at exposure, and 0.48 per Sievert for women aged 40 years and older at the time of the bomb. A higher occurrence of breast cancer was also observed among women who were younger than 10 years at the time of the bomb—a surprising finding because it is an age at which they would have had very little breast tissue. The latent period for radiogenic breast cancer is a minimum of about 10 years. Radiation-related breast cancers have age distributions and histopathologic characteristics similar to those of breast cancer from other causes, known or unknown.reasts should be shielded when possible when obtaining necessary diagnostic or therapeutic radiation. BRAIN CANCER The Japanese atomic bomb survivor data do not show an increase in brain cancer; however, studies of individuals exposed to therapeutic medical radiation do show an increased risk of brain tumors. In addition, there is evidence that the risk is higher in those exposed before age 20 years.In a follow-up study of children treated for tinea capitis, an increased risk of meningiomas was found in children exposed to 1 to 2 Gray (100 to 200 rad, average = 140 rad) of radiation to the brain.In a follow-up study of children treated for tinea capitis, an increased risk of meningiomas was found in children exposed to 1 to 2 Gray (100 to 200 rad, average = 140 rad) of radiation to the brain. http://www.balancedhealthtoday.com/xeneplex.html http://balancedhealthtoday.com/buy/xeneplex-ingredients/

do MICROWAVE Ovens cause CANCER?
Do microwave ovens cause cancer? Microwave ovens make use of microwaves which are one kind of radiation. ☛ Subscribe Our Channel For More #Lifestyle Videos! ☛ https://www.youtube.com/Top10Lifestyle Radiation is the light coming from the sun and the heat that is constantly coming from our bodies. It is the emission or sending out of energy from any source. X-rays are an example of radiation and so is a microwave. When we talk about radiation and #cancer, most of the people think of particular kinds of radiation such as x-rays or nuclear reactors radiation. But there are other types of radiation that act differently. Radiation is present in a spectrum of very high frequency radiation to very low frequency radiation. This is referred to as the electromagnetic spectrum. X-rays and gamma rays are the examples of high-energy radiation. Along-with these, some higher energy UltraViolet radiation is called ionizing radiation, which means they have enough energy to ionize an atom or molecule. This can result in damage to the DNA inside of cells, which can result in cancer. Radiofrequency (RF) #radiation, which is the combination of radio waves and microwaves, is at the end of the electromagnetic spectrum. It falls under non-ionizing type of radiation. Non-ionizing radiation with the help of energy can easily move atoms in a molecule or cause them to shake, but not enough to ionize i.e. remove electrons. Compared to other types of non-ionizing radiations, RF radiation has lower energy like visible light and infrared. When materials containing water, such as food, body tissues, and fluids absorb RF radiation can result in heat production which can lead to tissue damage and burns. Though damaging DNA in cells is not caused by RF radiation, the ionizing radiation does damage, and there has been concern that some forms of non-ionizing radiation might have biological effects that may result in cancer under some circumstances. The cellular activity in the humans is modified by microwaving which in turn damages the food. Our cells are forced by the damaged cells to adapt to an emergency mode of energy production. The cells produce energy production of glucose fermentation. This becomes a cancerous condition. The cancer cells cannot exist in oxygen. This is the reason why cancer patients should not eat foods made with sugar. While it is safe to use #microwaves, it is important to fact out that cooking in them can affect nutritional value of some types of foods like fruit and vegetables. But heating foods in any way like boiling, frying, steaming or grilling can cause loss of nutrients. As long the food is not overcooked, microwaving can be a healthy way to cook as it uses only little amount of water. The best way to keep fruits and vegetables full of nutrients is using as little water as possible and not to overcook them. The food is cooked at high temperatures in very little amount of time in microwaving. This can result into a great deal of nutrient loss, particularly vegetables. The foods also lose nutrients when they are boiled, fried or roasted. The boiling of vegetables may result into loss of most of the nutrients including antioxidants into the water. For only a slight loss of nutrients, they should be steamed. Baking at very low temperatures is also a feasible option that will hold more nutrients than frying, boiling or microwaving. To ensure a high level of nutrient intake, the diet should be taken raw. The effect of microwaves on antioxidants, proteins and nutrients can be understood by the help of science and research. To maintain the nutrition levels of our food, we should stick to the raw diet as far as possible. We can use steaming or baking as our main cooking methods instead of microwaving and can prevent cancerous cells formation.

How to avoid Mobile radiation Hazards
Why is there concern that cell phones may cause cancer or other health problems? There are three main reasons why people are concerned that cell phones (also known as “mobile” or “wireless” telephones) might have the potential to cause certain types of cancer or other health problems: Cell phones emit radiofrequency radiation (radio waves), a form of non-ionizing radiation, from their antennas. Parts of the body nearest to the antenna can absorb this energy. The number of cell phone users has increased rapidly. There were over 400 million cell phone subscribers in the United States in 2017, according to the Cellular Telecommunications and Internet AssociationExit Disclaimer. Globally, there are more than 5 billion cell phone usersExit Disclaimer. Over time, the number of cell phone calls per day, the length of each call, and the amount of time people use cell phones have increased. Because of changes in cell phone technology and increases in the number of base stations for transmitting wireless signals, the exposure from cell phone use—power output—has changed, mostly lowered, in many regions of the United States (1). The NCI fact sheet Electromagnetic Fields and Cancer includes information on wireless local area networks (commonly known as Wi-Fi), cell phone base stations, and cordless telephones. What is radiofrequency radiation and how does it affect the human body? Radiofrequency radiation is a form of electromagnetic radiation. Electromagnetic radiation can be categorized into two types: ionizing (e.g., x-rays, radon, and cosmic rays) and non-ionizing (e.g., radiofrequency and extremely low frequency, or power frequency). Electromagnetic radiation is defined according to its wavelength and frequency, which is the number of cycles of a wave that pass a reference point per second. Electromagnetic frequencies are described in units called hertz (Hz). The energy of electromagnetic radiation is determined by its frequency; ionizing radiation is high frequency, and therefore high energy, whereas non-ionizing radiation is low frequency, and therefore low energy. The NCI fact sheet Electromagnetic Fields and Cancer lists sources of radiofrequency radiation. More information about ionizing radiation can be found on the Radiation page. The frequency of radiofrequency electromagnetic radiation ranges from 30 kilohertz (30 kHz, or 30,000 Hz) to 300 gigahertz (300 GHz, or 300 billion Hz). Electromagnetic fields in the radiofrequency range are used for telecommunications applications, including cell phones, televisions, and radio transmissions. The human body absorbs energy from devices that emit radiofrequency electromagnetic radiation. The dose of the absorbed energy is estimated using a measure called the specific absorption rate (SAR), which is expressed in watts per kilogram of body weight. Exposure to ionizing radiation, such as from x-rays, is known to increase the risk of cancer. However, although many studies have examined the potential health effects of non-ionizing radiation from radar, microwave ovens, cell phones, and other sources, there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans (2). The only consistently recognized biological effect of radiofrequency radiation in humans is heating. The ability of microwave ovens to heat food is one example of this effect of radiofrequency radiation. Radiofrequency exposure from cell phone use does cause heating to the area of the body where a cell phone or other device is held (e.g., the ear and head). However, it is not sufficient to measurably increase body temperature. There are no other clearly established effects on the human body from radiofrequency radiation. What has epidemiologic research shown about the association between cell phone use and cancer risk? Researchers have carried out several types of epidemiologic studies in humans to investigate the possibility of a relationship between cell phone use and the risk of malignant (cancerous) brain tumors, such as gliomas, as well as benign (noncancerous) tumors, such as acoustic neuroma (tumors in the cells of the nerve responsible for hearing that are also known as vestibular schwannomas), meningiomas (usually benign tumors in the membranes that cover and protect the brain and spinal cord), and parotid gland tumors (tumors in the salivary glands) (3). In one type of study, called a case–control study, cell phone use is compared between people with these types of tumors and people without them. In another type of study, called a cohort study, a large group of people who do not have cancer at study entry is followed over time and the rate of these tumors in people who did and didn’t use cell phones is compared.

Health Effects Of Ionizing Radiation
http://www.balancedhealthtoday.com/xeneplex.html http://www.balancedhealthtoday.com/store/xeneplex.html Radiation damage to tissue and/or organs depends on the dose of radiation received, or the absorbed dose which is expressed in a unit called the gray (Gy). The potential damage from an absorbed dose depends on the type of radiation and the sensitivity of different tissues and organs. The sievert (Sv) is a unit of radiation weighted dose also called the effective dose. It is a way to measure ionizing radiation in terms of the potential for causing harm. The Sv takes into account the type of radiation and sensitivity of tissues and organs. The Sv is a very large unit so it is more practical to use smaller units such as millisieverts (mSv) or microsieverts (μSv). There are one thousand μSv in one mSv, and one thousand mSv in one Sv. In addition to the amount of radiation (dose), it is often useful to express the rate at which this dose is delivered (dose rate) e.g. μSv/hour or mSv/year. Beyond certain thresholds, radiation can impair the functioning of tissues and/or organs and can produce acute effects such as skin redness, hair loss, radiation burns, or acute radiation syndrome. These effects are more severe at higher doses and higher dose rates. For instance, the dose threshold for acute radiation syndrome is about 1 Sv (1000 mSv). If the dose is low or delivered over a long period of time (low dose rate), there is greater likelihood for damaged cells to successfully repair themselves. However, long-term effects may still occur if the cell damage is repaired but incorporates errors, transforming an irradiated cell that still retains its capacity for cell division. This transformation may lead to cancer after years or even decades have passed. Effects of this type will not always occur, but their likelihood is proportional to the radiation dose. This risk is higher for children and adolescents, as they are significantly more sensitive to radiation exposure than adults. Epidemiological studies on populations exposed to radiation (for example atomic bomb survivors or radiotherapy patients) showed a significant increase of cancer risk at doses above 100 mSv. Prenatal exposure to ionizing radiation may induce brain damage in foetuses following an acute dose exceeding 100 mSv between weeks 8-15 of pregnancy and 200 mSv between weeks 16-25 of pregnancy. Before week 8 or after week 25 of pregnancy human studies have not shown radiation risk to fetal brain development. Epidemiological studies indicate that cancer risk after fetal exposure to radiation is similar to the risk after exposure in early childhood. http://www.balancedhealthtoday.com/store http://balancedhealthtoday.com/products.html
