[Relationship of the biological effect of radiation to the area of irradiated body surface].

The dependece of radiation injury of piglets on the area of irradiated body surface (v 40 kv, Eeff 17 key, 1 10 mA per tube, additional filter 0.1 mm A1, delta 1/2 0.08 mm A1, source--skin distance 30 cm, R 504 r/min, radiattion dose 200 r) was studied. The biological effect was evaluated with respect to the clinical, hematological and biochemical changes in the animal body. The data were obtained that indicated burn disease in the irradiated piglets, severity of which increased with an increased with an increase of the area of irradiated skin surface.
