In this study a total of 396 male rabbits were used, theywere. divided into 3 main groups each of 32 animals, 110 ofwhich were irradiation ana 22 used as control.Irradiation of animals were performed using the siemersstabilipan type (300 KV, 14 - 8 M.A.) cu filter and 2 cu halfvalve thickness (H.V.T.) focus treating distance (F.S.D.) was50 cm dose rate 96,2 rad/minute at doses, 5OR., 150 R& ’500 Rwhole body.Animals were sacrified at 2H, 4H, 6H, IlH, 24H, 48H,72H, 1 week, 2 week, 3 week, and 1 month post irradiation,autopsied and eosinophil count, Histopathology and Histochemistryof adrenal cortex were performed.The results showed that no physical chunges in animaloohaviour or equilibrium, also no variation in the Histopatho-l~ical picture than the control, except at 12 H (500 R) con-qested blood vessels, witb some haemorrhagic areas were notice,t~ether with the presence of lacunae composed of degeneratedcells & some were invaded by inflammatory cells.Adrenal activity was tested by the eosinophilic count atdifferent times of sacrification: at 50 R activity was from4H to 6H: at 150 R was from 4H till l2H: while at 24H a marked .
