[Combined effect of ionizing radiation and exertion on various indices of non-specific resistance and immunity].

The paper submits the results of studies on the combined effect of a single external (3 Gy) and chronic internal (90Sr, 11.1 X 10(5) Bq/kg/day) X-irradiation and physical exercises of different kind and intensity on some indices of nonspecific protection and immunity of albino mongrel rats and mice. Moderate physical exercises preceding irradiation diminish radiation injury to the parameters under study while intensive exercises and stress may aggravate the damages.
