title: [Action of low doses of gamma-radiation on cytogenetic damage in polychromatophilic erythrocytes of bone marrow in mice in vivo].
abstract: The frequency of micronuclei was estimated in bone marrow polychromatic erythrocytes (PCEs) of mice gamma-irradiated in vivo at doses of 5-50 cGy. The dose-effect curve was found to have a complex stepwise pattern with three consequent segments: (1) high radiosensitivity, (2) a significant decrease in radiosensitivity, and (3) an increase in radiosensitivity.
