Chernobyl frogs exposed to radiation show no signs of stress or increased ageing
(phys.org)
The radiation levels experienced by the frogs living in Chernobyl have not affected their age or their rate of aging. These two traits do not differ, in fact, between specimens captured in areas with high levels of radiation and those living in control areas without radiation. Nor have differences been found in the levels of corticosterone, a hormone associated with the response to stress, depending on the radiation received by these amphibians.
