[The intellectual development of the children exposed to the influence of the ionizing radiation].
The mental development level of the children living in the territories polluted by the radioactive nuclide as the result of Cheernobil power plant damage, exposed to the prenatal irradiation, evacuated from the alienation zone, born from parents-liquidators (1st generation of the irradiated people) was evaluated. 177 children were examinated. The control group included 34 children not exposed to the radiation. The complex of psychometric methods--"D. Wexler children's intellectual test"--for 3-6-year-old children in the translation and adaptation of A.U. Panasyuk was applied for evaluating the intellect rate. In the structure of the observed groups the pathology diseases of nervous system, of digestion organs and the congenital anomalies prevailed. Clinical and instrumental investigation showed no differences in the neurology status between the observed and the control groups. It was proved that the intellect of the children exposed to the radiation corresponds the age standards. However, intellectual development of the children irradiated in the prenatal period and children evacuated from the 2nd zone of radioactive pollution (or living there) has a tendency to its decreasing. The determining role of social, of economic and of biologic factors (the parents' education, the region of living, the birth weight) in the intellect development was indicated.
