-Currently, doctors have no way to accurately measure damage to the body soon after a person is exposed to ionizing radiation. -It is therefore difficult to know whether a person is likely to suffer serious effects after an occupational or accidental exposure. -This animal study shows that radiation exposure alters the levels of certain small molecules in the blood, perhaps offering a reliable measure of damage to the body. Ohio State University cancer researchers have identified...

Each time a release of radioactivity occurs, questions arise and debates unfold on the health risks at low doses–and still, just over a year after the disaster at the Fukushima Nuclear Power Station, unanswered questions and unsettled debates remain. Now a special issue of the Bulletin of the Atomic Scientists, published by SAGE, examines what is new about the debate over low-dose radiation risk, specifically focusing on areas of agreement and disagreement, including quantitative...

Berkeley Lab Researchers Find Evidence Suggesting Risk May Not Be Proportional to Dose at Low Dose Levels Researchers with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab), through a combination of time-lapse live imaging and mathematical modeling of a special line of human breast cells, have found evidence to suggest that for low dose levels of ionizing radiation, cancer risks may not be directly proportional to dose. This contradicts the...

TUCSON, Ariz., June 1, 2011 /PRNewswire-USNewswire/ -- Japan's already reeling economy could be crushed by over-reaction to the Fukushima disaster, warns radiation scientist T.D. Luckey in the summer 2011 issue of the Journal of American Physicians and Surgeons. www.jpands.org/vol16no2/luckey.pdf Japan should not repeat the mistake that Russia made in the tremendous unwarranted expense of its reaction to Chernobyl. As Mikhail Gorbachev understood too late, "The nuclear meltdown at...

JOHNSON CITY, Tenn., March 19, 2011 /PRNewswire/ -- Recent events in Japan have caused the world to focus on unintended radiation exposure. Exposure to radiation can be a cause for concern - especially if radiation levels reach or exceed 1 Gy. Radiation targets rapidly proliferating cells of the body. Cells of the hematopoietic system (bone marrow) and the gastrointestinal (GI) tract are two such cell types. Damage to these cells initiates programmed cell death (apoptosis). First...

Contrary to common assumptions, the risk of cancer associated with radiation exposure in middle age may not be lower than the risk associated with exposure at younger ages, according to a study published online October 25 in the Journal of the National Cancer Institute. It is well known that children are more sensitive than adults to the effects of radiation and that they have a greater risk of developing radiation-induced cancer than adults. Some data also suggest that, in general, the older...

Diagnostic X-rays may increase the risk of developing childhood leukemia, according to a new study by researchers at the University of California, Berkeley's School of Public Health. Specifically, the researchers found that children with acute lymphoid leukemia (ALL) had almost twice the chance of having been exposed to three or more X-rays compared with children who did not have leukemia. For B-cell ALL, even one X-ray was enough to moderately increase the risk. The results differed slightly...

For decades, we have been told that exposure to radiation is dangerous. In high doses it is certainly lethal and chronic exposure is linked to the development of cancer. But, what if a short-term controlled exposure to a low dose of radiation were good for our health. Writing in today's issue of the Inderscience publication the International Journal of Low Radiation, Don Luckey, makes the startling claim that low dose radiation could be just what the doctor ordered! Luckey, an emeritus...

In June 29 WASHINGTON story headlined "Study shows radiation causes cancer but rarely" please read in fourth paragraph ... the equivalent of 1,000 chest X-rays ... instead of ... the equivalent of 10 chest X-rays ... A corrected story follows: WASHINGTON (Reuters) - Exposure to everyday sources of radiation, mostly medical X-rays, raises the risk of cancer but not by much and there is no clear line between a harmless dose and a disease-causing dose, an expert panel reported on Wednesday....
