Results of studies of peculiar properties of progesterone content in blood serum of outbred female rats under the influence of intensive ionizing radiation against the background of stress stimulation realized in the conditions of the Republic of Belarus were presented. There were the following animal groups: 1. controlled rats; 2. irradiated rats; 3. stressed animals; 4. rats subjected to ionizing radiation and stress. Research results showed that concentration of progesterone in serum blood of female rats in 3 days after immobilized stress decreased on 40% in comparison with the control indexes. More intensive decreasing of hormone level took place after irradiation in dose of 1 Gy (on 62% in comparison with the controlled group). Combine activity of ionizing radiation and stress involved the decreasing of hormone concentration on 25% in comparison with the controlled group. In ten days there was the restoration of changes. Increase of progesterone concentration in blood serum took place in all tested groups. Hormone level in blood serum of irradiated rats increased on 46,04 nmol/l in comparison with results of the third day after irradiation. Hormone level in blood serum of stressed animals increased on 11,63 nmol/l, in group subjected to the combined activity of ionizing radiation and stress – on7,65nmol/l. On the thirtieth day the indexes of progesterone concentration in blood serum of irradiated rats, stressed rats and rats subjected to ionizing radiation and stress were almost similar to the control indexes
