Submission + - MIT Study: Prolonged Low-level Radiation Damage Heals (mit.edu)

JSBiff writes: A new study from MIT scientists suggests that the guidelines governments use to determine when to evacuate people following a nuclear accident may be too conservative.

The study, led by Bevin Engelward and Jacquelyn Yanch and published in the journal Environmental Health Perspectives, found that when mice were exposed to radiation doses about 400 times greater than background levels for five weeks, no DNA damage could be detected.

Submission + - Berkeley Research Suggests Low Radiation Damage Do 1

JSBiff writes: Breast Cancer researches at the Berkeley National Lab will be publishing a study, in which they, "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 standard model for predicting biological damage from ionizing radiation – the linear-no-threshold hypothesis or LNT – which holds that risk is directly proportional to dose at all levels of irradiation."

The evidence grows that low-level radiation should not be viewed as a threat to public health.
