[Role of nonspecific cellular resistance factors in hygienic evaluation of electromagnetic nonionizing radiation].

The most sensitive indices of the blood system at EMF exposure (disorders of megakaryocytes differentiation, unspecific reactions, repopulation of the blasts cells a. al.) have been determined by the cytologic investigations. At has been revealed that allowable UVF levels effect are situated below the threshold of activisation of adaptive reactions (less than 0.01 mV/cm2), for occupational conditions--at the level of compensatory processes (0.05-0.1 mV/cm2). The intensities higher than 0.5 mV/cm2 were estimated as critical. Involution of megakaryocytes, polimorphism and disturbances the structure of leucocytes a. al. were revealed as EMF markers which allow to carry out an express-diagnostic.
