radiation, ionizing

Although it has been claimed that radiation causes accelerated aging, there is no evidence to support it. In laboratory animals, chronic radiation causes an increased mortality rate. Although there is an increase in mortality rates, there does not seem to be an acceleration of the aging process. The laboratory animals did not show any of the physiological changes of aging before they died. People who are born and live permanently in areas with radioactivity do not appear to age more quickly than others.
