Low Doses of Radiation Linked To Small Increase in Cancer Risk

Cancer Risk and Radiation

Current radiation protection standards based on exposure to A-Bomb


The standards used for radiation protection around the world today are primarily based on an extrapolation of risk estimates derived from studies of the survivors of atomic bombings in Hiroshima and Nagasaki in August 1945. The main issue of concern however is the protection of the general public and of occupationally exposed workers, who generally receive much lower doses, protracted over many years.

For Dr Elisabeth Cardis, of the IARC Radiation Group, "There has been a controversy for decades about the use of data on A-bomb survivors for setting standards for the protection of the general public and radiation workers. There was therefore a need for a direct assessment of the carcinogenic effects of low-dose exposures to evaluate the adequacy of these standards."
