Genetic effects in somatic and germ cells, induced by ionizing radiations

Quantitative data are reported on injuries to hereditary structures in somatic and sex cells, induced by different types of ionizing radiation. The model systems used were human peripheral blood lymphocytes, in vitro irradiated with different doses: bone-marrow cells of mice and rats irradiated in vivo: mouse, rat, rabbit and hamster sex cells. To evaluate the dose-effect dependency after acute and chronic irradiation, the authors used mathematical models, describing the amount of chromosomal injuries. Attempt was made to estimate the somatic and genetic risk, following acute and chronic irradiation with different doses of ionizing radiations. (authors)
