ONCOHEMATOLOGICAL ASPECTS OF IONIZING-RAD IATIONS EXPOSURE ON HUMAN EMBRYO AND FETUS

Today it is mot yet clear whether radiation exposure in perinatal peri od is a causative or associative factor for increasing incidence of le ukemia among the children. Relatively short latent period between irra diation and the development of radiation-induced leukemia has been con firmed in several studies. The comparative investigations of cancer ri sk for the children, who were exposed in utero and at the age of 0-9 y ears were made. The data of long-term study provide some evidence that the effects of the radiation exposure in utero aren't limited to the childhood but persist in their early years. The discovery of possible mechanism of leukemias induction in the children of occupationally exp osed workers and irradiated parents needs further research.
