High radiation doses put a significant number of dialysis patients at increased risk of cancer, according to a study appearing in an upcoming issue of the Journal of the American Society Nephrology (JASN). The results suggest that clinicians should consider scaling back on radiation for purposes of diagnosis in this patient population.Many kidney disease patients on dialysis suffer from other illnesses that require them to undergo radiation procedures for diagnosis and treatment. This means...
(Ivanhoe Newswire) -- Cardiac imaging tests, such as CT scans could be putting heart attack patients at a higher risk of cancer.According to a new study, exposure to low-dose radiation is associated with an increased risk of cancer. Typically, the amount of radiation that patients are exposed to is so small that it doesn't pose a major health risk, but when there are multiple scans the damage can start to add up.Patients with known or suspected coronary artery disease, tend to have more...
Exposure to low-dose radiation from cardiac imaging and other procedures after a heart attack is associated with an increased risk of cancer, found a new study published in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj100463.pdf.The use of procedures with low-dose ionizing radiation, such as computed tomography (CT) angiography and nuclear scans, is increasing which has led to mounting concern in the medical community that patients may be...
Medical physicists at Thomas Jefferson University and Jefferson's Kimmel Cancer Center have demonstrated a new real-time tumor tracking technique that can help minimize the amount of radiation delivered to surrounding healthy tissue in a patient"”up to 50 percent less in some cases"”and maximize the dose the tumor receives.Respiratory and cardiac motions have been found to displace and deform tumors in the lung, pancreas, liver, breast, and other organs. Because of this, radiation...

The Radiaderm Skincare System is a simple 2-step...
PRINCETON, N.J., Jan. 18, 2011 /PRNewswire/ -- Soligenix, Inc. (Soligenix or the Company) (OTC Bulletin Board: SNGX), a late-stage biopharmaceutical company, announced today promising preliminary results from a preclinical study of SGX202 (oral beclomathasone dipropionate or BDP) in a canine gastrointestinal acute radiation syndrome (GARS) model. The results indicate that dogs treated with SGX202 demonstrated statistically significant (p=0.04) improvement in survival after exposure to...
First in the Richmond, Va., area to use cutting-edge VMAT radiation equipment Richmond, Va. (Vocus/PRWEB) January 11, 2011 Virginia Commonwealth University Massey Cancer Center has introduced a safer and more effective form of radiation therapy to treat cancer. The Center now offers volumetric modulated arc therapy (VMAT) delivery using the Philips Pinnacle3 SmartArc software to provide radiation treatment for multiple tumor sites, including prostate, head and neck, brain, breast and...
Members of the engineering faculty at Oregon State University have invented a new type of radiation detection and measurement device that will be particularly useful for cleanup of sites with radioactive contamination, making the process faster, more accurate and less expensive.A patent has been granted on this new type of radiation spectrometer, and the first production of devices will begin soon. The advance has also led to creation of a Corvallis-based spinoff company, Avicenna...
(Ivanhoe Newswire) -- Children are exposed to a lot if things that they probably shouldn't be; unfortunately, some instances are worse than others. It was reported that children exposed to head and neck radiation -- due to either cancer treatment or multiple diagnosis computed tomography (CT) scan "“ have an increased risk of thyroid cancer for the next 58 years . . . and possibly even longer than that.Authors state that the data may provide insight into exactly why the rates of...
Researchers from the University of Santiago de Compostela (USC) have analysed levels of radon, a natural radioactive gas, in 58 secondary schools in Galicia. The results show that 34% of these schools exceed the limit of 400 Bequerels/m3 recommended by the European Union. Excessive inhalation of radon is associated with lung cancer."Out of all the secondary schools where samples were taken, 34% had radon levels in excess of 400 Bequerels/m3 in some of their classrooms or offices",...

Nuclear fallout, or just simply fallout, known also as Black Rain, is the residual radioactive material that is propelled into the upper atmosphere after a nuclear black or a nuclear reaction that is conducted in an unshielded facility. It is so called because it "fall out" of the sky after the explosion and the shock wave have passed. It most commonly refers to the radioactive dust and ash that is created when a nuclear weapon explodes, but such dust can also come from a damaged nuclear...
Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
