Ionizing Radiation Extends Life

Low radiation doses extend human life, Russian biologist says. Ionizing radiation affects genes, which are responsible for cell ageing.

Billions of cells are exposed to natural ionizing radiation. Evolution should have created an effective means for protecting cells from small radiation doses. Thus, the fact that X-rays and gamma rays in low and medium doses extend life of various laboratory animals on 10-29% is not surprising.

Small doses of radiation promote immunity and cell division, as well as initiate other mechanisms of cell defense. But another explanation exists.
