Vitamin D radio protection

Radiological health expert Daniel Hayes of the New York City Department of Health and Mental Hygiene has found that a form of vitamin D, calcitriol, could help protect the body against cellular damage caused by low levels of radiation. Writing in the International Journal of Low Radiation, he suggests that this active form of the vitamin might be given as a supplement, not only to protect people from background radiation, but also to reduce the health impact of a low-level nuclear incident, such as a leak from a nuclear power station or a terrorist dirty bomb.
