[Lung histopathology during plutonium-238 incorporation].

: In experiments with albino mongrel female rats a study was made of the response of the lungs to a single intratracheal injection of nitrate of 238Pu (0.4-740 kBq/kg). The nature of the inflammatory disease, the lymphoid tissue condition, pneumosclerosis occurrence, and the frequency and spectrum of lung tumors were shown to be a function of dose of the radionuclide administered.
