[Health state and physical development of children prenatally exposed to radiation as a result of Chernobyl accident].

1144 children which had been exposed to radiation at the stage of their intrauterine life have been observed. Assessment of their health state and physical development has been carried out. Radiation doses load on thyroid gland of fetuses varied from 0.01 till 3.34 Gr, whole-body irradiation doses varied from 10.0 till 376.0 mZb. The level of health state of children exposed during their intrauterine life to radiation was lower at all stages of postnatal ontogenesis than that one of children of the control group. A presence of a definite correlation ratio between whole-body irradiation doses of fetuses and development of chronical somatic pathology in children was established during the study. It was noted that frequency of abnormalities of physical development and chronical somathic pathology increased after a thyroid gland of the fetuses had been exposed to radiation dosed from 0.36 to 0.75 Gr.
