As a result of contamination of the river Techa by fission products in
1949-1956, the residents of the riverside villages were exposed to ex
ternal and internal irradiation. The average gonadal dose in the study
cohort of 28 100 people is estimated to be 0.16 Sv. No decrease in fe
rtility and birth rate was detected. The gonadal doubling dose ranges
calculated for the incidence of stillbirths. miscarriages, early neona
tal mortality and lethal developmental defects was found to be rather
high, ranging from 0.2 to 4.8 Sv.
