[Limited genetic monitoring in Kiev in relation to the accident at the Chernobyl Atomic Electric Power Station].

Frequency of innate developmental defects, perinatal death rate, spontaneous and induced abortions were statistically studied on the basis of primary medical information from archives of two largest maternity hospitals of Kiev for the period between 1969 and 1989. Significant variations in the chosen characters in different years were found, unidirectional changes in time being absent. No increase in the number of innate defects and frequency of spontaneous abortions after 1986 was found. It is shown necessary to introduce a system of unified registration of innate developmental defects adopted by an international register as well as to use more perfect mathematical methods for correct estimation of the processes occurring in human populations.
