Abstract
Albino male rats were divided into four groups and exposed to gamma-radiation (137Cs) for 80, 40, 20 and 10 days at dose rates of 0.25, 0.5, 1.0 and 2.0 Gy/day, respectively. The development of lesions and remote aftereffects was shown to depend upon conditions of formation of the absorbed dose. With fractionated irradiation at dose rates above 1.0 Gy/day the dose-rate played a major role in producing the effect.
