After gamma irradiation within a wide range of doses (from 5 to 100 Gy) it was found that behavioural response of an emotional type (an evoked "pleasure" test) was more labile than the reaction based on a pronounced congenital hunter motivation (a "predator-victim" test). Exposure (50 Gy) of abdomen, when CNS was unaffected while a pronounced vegetative syndrome of the primary reaction developed within the first two hours, resulted in a more significant decrease in either behavioural pattern than it was observed after irradiation of the head.

After local irradiation of heads with doses of 50 to 100 Gy cats and dogs exhibited two types of a loss of sight: early blindness (during the first two hours) noted only in cats after a dose of 100 Gy, and delayed blindness in cats after a dose of 50 Gy, and in dogs after all doses under study.

A decrease in the degree of manifestation of the induced pleasure response of male cats to the administration of valerian tincture was observed during the first 1-2 h following gamma-irradiation of the head with a dose of 1.29 C/kg. It is suggested that the absence of the reaction during the first 10-15 min after exposure is indicative of the presence of the phase of a pronounced excitation in the C.N.S. of the exposed animals.

This paper presents data on vomiting as a primary dose-dependent reaction of dogs to irradiation. It is shown that vomiting can be predicted with reference to the average absorbed dose in the abdominal area, provided the animal is irradiated in a lethal dose and the area is shielded. It is emphasized that calculated and experimental data are in good agreement.
