[The genetic consequences of the Chernobyl accident. The monitoring of congenital developmental defects in newborn infants in Kaluga Province].

The study concentrates on the genetic after-effects of the Chernobyl accident in some districts of Kaluga Province. The frequencies and range of congenital malformations, prematurely death-rate in the radionuclear polluted districts were compared with the control districts. Prematurely death-rate in compared regions is the same. The increase of the congenital malformation frequency is revealed in one the polluted districts (256/10,000) as compared with the control one (27/10,000). We assume that the observed effect is mainly connected with the professional activity of the population.
