Peat Archive

Ray Peat wrote extensively about radiation, drawing on research showing that even low-dose radiation has biological effects that are systematically underestimated by regulatory bodies. He argued that the 'linear no-threshold' model actually underestimates harm at low doses because of bystander effects — where irradiated cells signal damage to neighboring unirradiated cells. He documented the political and military pressures that have shaped radiation safety standards since the atomic bomb.

Peat also discussed the protective effects of certain substances against radiation damage: thyroid hormone (which speeds DNA repair), progesterone, vitamin E, and aspirin. He noted that people living near nuclear facilities, receiving repeated medical X-rays, or exposed to fallout have measurable increases in cancer and birth defects, often dismissed by authorities using statistical methods designed to minimize apparent harm.
