Exploring the effects of low-dose radiation
 
02:21
Radioactivity existed since the beginning of the universe. But while the effects of high-dose radiation are widely explored, the impact of human exposure to low-dose radiation is not fully understood. An important landmark in the research field of low-dose radiation is the EU-funded research project GENRISK-T. Cancer scientists and radiation biologists at six European laboratories collaborated to study the risk of thyroid cancer after exposure to ionizing radiation.

Medical Radiation and cancer risk: assessing the price of progress
 
01:02:03
Medical Radiation and cancer risk: assessing the price of progress Air date: Friday, January 11, 2013, 12:00:00 PM Category: NIH Director's Seminars Runtime: 01:02:02 Description: NIH Director's Seminar Radiation exposure to the US population from diagnostic imaging has increased 6-fold in the last three decades, primarily due to the rapid increase in CT scans from 1 to 80 million per year. Despite the great medical benefits there are concerns about the potential future cancer risks from CT and other higher dose imaging tests such as nuclear medicine cardiac stress tests. Dr. Berrington's Radiation Epidemiology Branch conducted the first study to directly assess the cancer risks after CT scans in a historical cohort study of 200,000 children in the UK. Dr. Berrington will discuss the first results from this study and also present risk projections for the number of future cancers in the US that may be related to diagnostic imaging in children and adults if use continues at current levels. Recently a number of new screening tests such as lung CT and CT colonography have been proposed for use in the general population, and newer radiotherapy techniques like proton therapy have become more widespread. Dr. Berrington will also describe work that she has conducted that assesses the balance of the potential benefits against the radiation-related cancer risks for these emerging technologies.

Effects of Radiation: 1. Increased, spontaneous abortion 2. Shifts in red and white blood cell counts 3. Increased somatic mutation in lymphocytes 4. Increased childhood cancers Alternatives to Microwaves: Rather than using a microwave, use: 1. Stove 2. Convection oven These methods take a bit more time, but it is well worth it! Action Steps: 1. Replace your microwave with the stove or a convection oven. 2. Use headphones to talk on cell phones. 3. Try to avoid airport scanners by opting for a pat-down. 4. Try to reduce overall radiation exposure over time.

Radiation Exposure ,Radiation safety- Everything You Need To Know - Dr. Nabil Ebraheim
 
07:46
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.

CT radiation and cancer risk
 
05:05
It has been known for decades that radiation exposure increases cancer risk. Most of the evidence comes from analysis of atomic bomb survivors. Almost all data I can find is based on the same data. Basically, 20% of Americans will doe of cancer in general (400 in 2000). Being exposed to 10 milli-Sievert (mSv) of radiation increases risk by 0.05%, or 1 additional cancer in 2000. A CT scan is between 2-10 mSv of radiation. Natural occurring radiation from space and ground based radiation like Radon, is 2 mSV of radiation per year. The link between CT radiation and cancer has been known for some time, and modern machines and techniques are able to reduce the amount of radiation per scan, as compared to the amount when the literature was written. Cancer risk does still exist, and you should have a conversation with your doctor about the possible risks AND benefits of doing CT. As well as if another type of test like ultrasound or MRI would be an appropriate alternative.

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."

Why cancer may require a higher radiation dose in diagnostic imaging
 
02:07
If you have concerns about the safety of various diagnostic scans, especially those that expose you to ionizing radiation on a regular basis, watch MD Anderson experts explain some myths about diagnostic imaging and why certain levels of radiation are required. Not all diagnostic imaging involves ionizing radiation. (Ultrasound and MRI are two exceptions.) But for those that do, MD Anderson doctors use the lowest doses possible to get the answers they need. The risks of radiation exposure through medical testing are actually very small — and still theoretical. But MD Anderson minimizes even those risks by tailoring the amount of radiation to the size of each patient, as well as to the purpose of each scan. Learn more about [insert cancerwise link]

Doing More with Less: Radiation Doses Dropping - Mayo Clinic
 
05:03
Many misconceptions exist about the risks associated with radiation doses and CT scans. Experts at Mayo Clinic want patients to have the right information about radiation dose, including when to have procedures with radiation, such as a CT scan, versus when to have magnetic resonance imaging or other non-radiation tests. Since 2001, a team of diagnostic radiologists and medical physicists at Mayo Clinic have been actively developing and implementing new techniques to lower doses from CT. They have installed new CT scanners and software and implemented new scanning instructions to lower the doses for more than 100 different CT protocols. Amy Hara, M.D., a diagnostic radiologist at Mayo Clinic Arizona, says that doses have dropped more than 50 percent for several scan types. She emphasizes that their goal is to reduce the radiation dose without compromising the image quality — and advances in technology are making that possible.

Low-Dose CT Scans
 
01:35
Sometimes less really is more - that certainly applies to low-dose CT scans. "Any type of x-ray radiation, even the smallest dose, carries a very small risk. And when you multiply that over millions of people, that risk is real and results in several radiation induced cancers," says Dr. Cory Duffek, neuroradiologist on the medical staff of Lee Memorial Health System. Over the past few decades, the amount of radiation emitted during even the standard CT scan is between 20 and 30% lower. With new technology, a single machine can deliver various doses, depending on the patient and procedure. "We go through a long process deciding with each and every scan that we do, exactly how much radiation we're going to be using and how much of the new software available to us we're going to be using, in order to try and maintain the same amount of image quality but decrease the dose," says Dr. Duffek. Low-dose scanners combine the best of both worlds. Providing detailed images while managing to lower the amount of radiation. It is especially important when it comes to children who are more sensitive than adults. "There's been a big push to use what we call a pediatric dose for pediatric scanning. With our new generation of scanners now, it allows us to lower that dose approximately another 15 to 30%," says Dr. Duffek. Exploring the body with the minimal risk to the patient makes low-dose scanners a screening super sleuth.

What is a low-dose CT scan?
 
03:21
Dr Jeffrey Goree explains what a low-dose computerized tomography (LDCT) scan is. The Waddell Lung Initiative is funded by a grant from the Genesis Philanthropy and JoAnn Waddell Regional Fund for Hospice and Cancer Care Lung cancer is the leading cause of death from cancer. Early screenings usually are not covered by Medicare or insurance and by the time the cancer is detected, it is often too far advanced for most treatments to be successful. Minorities are at a higher risk to have lung cancer detected in late stages than the general population. This project provides at no cost to participants a preliminary assessment of potential risk of lung cancer through an online survey, and for those who are deemed high risk, a low-dose computerized tomography (LDCT) scan at any Genesis Imaging Center.

Invisible Impact: The Risk of Ionizing Radiation on Cath Lab Staff
 
05:58
This video tells the story of one of the world’s most prominent cardiovascular surgeons, Dr. Edward Diethrich, and the career-altering health issues he has faced as a result of chronic, low-level exposure to ionizing radiation through his work. Catheter-based technology has enabled the minimally invasive treatment of conditions that previously required invasive surgery. However, as the number of interventional procedures performed each day continues to rise, an unforeseen trade-off relates to the health of the medical professionals who perform these procedures and are exposed to procedure-related ionizing radiation. Existing scientific evidence points to an alarming incidence of cancer, cataracts and other serious adverse health effects among these professionals, including interventional cardiologists, endovascular surgeons, interventional radiologists and neurointerventionalists, as well as fluoroscopy lab employees. The Organization for Occupational Radiation Safety in Interventional Fluoroscopy (ORSIF) was formed to raise awareness of the health risks of occupational ionizing radiation exposures and associated musculoskeletal risks occurring in interventional fluoroscopy laboratories. ORSIF develops support for medical professionals and hospitals for new and better ways to create the safest possible work environment for those dedicated to the wellness of others. The organization is comprised of members from industry and also includes physicians and staff from interventional fluoroscopy labs, and will partner with other physician associations, academic institutions, labor groups, and government bodies.

Low Dose CT Scans to Look for Lung Cancer
 
01:44
It's estimated a quarter million Americans will be diagnosed with lung cancer this year. It's the leading cause of cancer deaths for both men and women. More than half of patients find out they have lung cancer when it's almost too late. Lung cancer continues to frustrate doctors and decimate patients. It's one of the most commonly diagnosed and most lethal of cancers. "Unfortunately most of the patients present in late stages of disease. And the reason is that many times it doesn't have very specific symptoms," says Dr. Frank Rodriguez, an oncologist with Lee Memorial Health System medical staff. Doctors have long searched for a reliable screening test, in particular for high risk groups including smokers over the age of 55, those with a history of second hand smoke exposure, and anyone with occupational exposure to inhaled chemicals. Many doctors used chest x-rays to look for early tumors. "The problem with chest x-rays is that they're not very specific or sensitive, meaning that they often can't delineate or separate good things from bad things," says Dr. Rodriguez. Instead of giving up, researchers looked deeper into more advanced x-ray technology to find something more reliable that might save lives. "There's a better alternative now. There's something called a Low Dose Computerized Tomography, or low dose CAT scan, which basically looks at the lungs and the chest in a way that gives much more information than on a regular x-ray," says Dr. Rodriguez. A low dose, spiral CT scan generates a 3D image in a matter of seconds while keeping radiation exposure to a minimum. It is more successful at finding lesions. Studies find it's better than standard x-rays. "They could actually compare to plain x-rays decreased risk of mortality of lung cancer by 20 percent, which is a significant number," says Dr. Rodriguez. Sixty percent of lung cancers are currently picked up in late stages. Something with the potential to find cancer early could be the game changer doctors are looking for.

Jay Gutierrez is considered an expert in the field of "Natural Radiation Hormesis", having traveled several times around the country and working with scientists, doctors, healers, and clients. They have been successfully fighting and healing serious degenerative and life threatening diseases such as cancer and many, many others. And it is saving the honey bees. Night Hawk Minerals, their company, is the only major U.S. company they are aware of that actively promotes the use of natural radiation hormesis. http://www.nighthawkminerals.com Jay works with his colleague Dr. Raphael d'Angelo, who is his Medical Director and Parasitologist for their clients. Jay and Dr. d'Angelo have toured many parts of the U.S. speaking about the phenomenal healing aspects of "Radiation Hormesis". ****************** The late Galen Winsor, a nuclear physicist of renown who worked at, and helped design, nuclear power plants in Hanford, WA; Oak Ridge, TN; Morris, IL, San Jose, CA; Wilmington, NJ. Among his positions of expertise he was in charge of measuring and controlling the nuclear fuel inventory and storage. Galen Winsor traveled and lectured all over America, spoke on national talk radio, and made several videos exposing the misunderstood issues of nuclear radiation. He shows that fear of radiation has been exaggerated to scare people ... so a few powerful people can maintain total control of the world's most valuable power resource.

Low Dose CT Screening for Lung Cancer Video – Brigham and Women’s Hospital
 
04:46
Lung cancer is the most frequent cause of cancer death in this country and around the world. In 2014, the American Cancer Society projects 224,000 new cases of lung cancer and 159,000 Americans are expected to die from lung cancer. Lung cancer is a very serious health concern caused in large part, but not entirely, by smoking. Francine L. Jacobson, MD, MPH of Brigham and Women’s Hospital, advises patients to stop smoking to decrease their risk of developing lung cancer. If you have stopped smoking, she advises, you still have a significant risk of developing lung cancer. In the age group 55 to 80, the risk is significant enough to warrant screening on an annual basis. The screening is currently done with a very low dose of radiation in a CT scanner. Dr. Jacobson notes that one life is saved for every 320 lung cancer screenings. Learn more about Lung Cancer Screening: http://www.brighamandwomens.org/lungscreening

⚛ Chernobyl Cancer Study Confirms Risk ⚛

All studies cited… New study reviewed Kashcheev et al. (2014). Incidence and mortality of solid cancer among emergency workers of the Chernobyl accident: assessment of radiation risks for the follow-up period of 1992-2009. Radiation and Environmental Biophysics. Oct 15. http://pubmed.gov/25315643 Meta-analyses of radiation-worker studies cited @ 1:56 Jacob et al. (2009). Is cancer risk of radiation workers larger than expected? Occupational and Environmental Medicine, 66(12):789–96. http://pubmed.gov/19570756 Relevant quote of Jacob: "The ICRP and BEIR VII base their DDREFs mainly on radiobiological results including animal data, which, in their majority, suggest a characteristically low risk for low-dose-rate exposures. It remains an open question as to why this characteristic is apparently not reflected in the human epidemiological data." Cardis et al. (2007). The 15-Country Collaborative Study of Cancer Risk among Radiation Workers in the Nuclear Industry: estimates of radiation-related cancer risks. Radiation Research, 167(4):396-416. http://pubmed.gov/17388693 Relevant quote of Cardis: "Risk estimates per unit dose from this study are statistically compatible with estimates that serve as the basis for current radiation protection standards. They range from values lower than the BEIR VII estimates up to values that exceed these estimates by a factor of about six for both solid cancers and leukemia. This is the largest analytical epidemiological study of the effects of low-dose protracted exposures to ionizing radiation to date." So the radiation-worker epidemiology (involving slow-dose rates) match or exceed the risk of BEIR VII, which is based on the atomic-bomb cohort (involving a fast-dose rate). So it seems dubious that slow dose rates are less harmful, and Kashcheev (2014) adds to that impression. Other Chernobyl worker solid-cancer studies cited @ 2:05 Rahu et al. (2013).

Effects of Ionizing Radiation
 
15:45
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

Using mice as mammalian animal model, we applied a single dose of 0, 0.063, 0.125 and 0.5 Gy at 10 weeks of age, determined lens opacities for up to 2 years and compared it with overall survival, cytogenetic alterations and cancer development. The highest dose was significantly associated with increased body weight and reduced survival rate. Chromosomal aberrations in bone marrow cells showed a dose-dependent increase 12 months after irradiation. Pathological screening indicated a dose-dependent risk for several types of tumors. Scheimpflug imaging of the lens revealed a significant dose-dependent effect of 1% of lens opacity. Comparison of different biological end points demonstrated long-term effects of low-dose irradiation for several biological end points. - video upload powered by https://www.TunesToTube.com
