Abstrakt: The study was aimed at evaluating the radioprotective effectiveness of beta-estradiol following its prophylactic administration in conditions of acute irradiation. Evaluation of the radioprotective efficiency was performed by studying the 30-day survival rate, life expectancy, the structure of irradiated mice death, the bone marrow hematopoiesis using the method of exogenous colony formation. The prophylactic use of beta-estradiol at doses of 20 and 40 mg/kg 5 days before irradiation has been established to protect the exposed mice against radiation death induced by X-rays at doses LD50-90/30, thus increasing their survival rate by 17-58%, and to favor the reduced expression of post radiation disorders of bone marrow hematopoiesis.
