[Immunity after exposure to radiation].

The results of proper investigations and literature data obtained while studying the effect of single general radiation, radioisotopes of iodine, strontium and cesium on experimental animals are presented. The data thus obtained enable one to form a pattern of radiation-induced injuries within the nearest and remote period of time following radiation accident. Impairments of nonspecific humoral and cell protection T- and B-immunity systems and the onset of autosensitization are of great significance for the nearest (infection) and late radiation effects (malignant neoplasms, cataracts, aging, disorders of the reproductive function) and should be taken into account in hygienic assessment of potential health variations and shaping of preventive activities.
