[Non-mutagenic non-targeted radiation effects. Determined decrease of cells viability in populations induced by low dose radiation].
Experimental data obtained from studies on the objects with different organization were analyzed. These data expand the ideas about the phenomenon of "viability determinate decrease in offspring of irradiated cells" discovered in the 1970s. This phenomenon was evaluated according to the standpoint of modern radiobiology. It is postulated that the studied effects, which are associated with the cytoplasmic structures damage and are clearly manifested in mammalian low proliferative tissues, can be significant for humans in connection with the delayed somatic consequences of low dose irradiation, as well as with a more general problem of longevity reduction. Possibility of inheritance ofthese alteration in protozoa asexual reproduction and metazoan sexual reproduction (generation F1) is demonstrated.
