Gamma rays have no effect on lifespan in mice.
“Mean life spans were not significantly different among the LDR exposed groups compared to the non-irradiated controls”

Gamma rays shorten lifespan in mice.
“the life spans of those exposed to the MDR were significantly shorter than the non-irradiated controls”

Gamma rays have no effect on lifespan in mice.
“In all experiments that displayed enhanced longevity the average life span was enhanced by 10-30% but not the maximum life span potential.”

Gamma rays extend lifespan in C. porcellus.
“data emerged suggesting that low dose rates/cumulative doses enhanced longevity in mice and guinea pigs of both sexes.”

Gamma rays raise the risk of multiple primary neoplasms in mice.
“Multiple primary neoplasms were significantly increased only in females exposed to MDR.”
