[Motor activity of rats after gamma irradiation in large doses]

In experiments on 80 Wistar male rats their motor activity was studied using "Optovarimex" device which permitted to register the position of animals in space. The rats were subjected to total-body gamma-irradiation with doses of 6.5, 13, 50 and 100 Gy. The motor activity was studied 1, 24, 72 and 96 h following irradiation. Inhibition of the motor activity of animals was shown to depend upon radiation dose.
