Pollycove and Feinendegen have made a theoretical ar The committee has reviewed evidence for "hormetic ef- gument that the hazards of radiation exposure are negligible fects" after radiation exposure, with emphasis on material in comparison to DNA damage that results from oxidative published since the previous BEIR study on the health ef- processes during normal metabolism. They argue that enfects of exposure to low levels of ionizing radiation.
