[Life-span of rats as affected by a combination of external (137Cs) and internal (237Np) radiation]
Abstract:
A study was made of a change in the mean life of rats exposed to external gamma-radiation (51.6 mC/kg) and 237Np (a polymeric nitrate form) administered intratracheally (0.2-188.0 kBq/kg) delivered separately and in a combination. It was established that the effects of gamma- and alpha-radiation were summated.
