[The rate and structure of infant mortality in a town situated near an industrial nuclear enterprise].
The paper is devoted to analysis of the rates and structure of mortality of infants aged under 1 in a town, situated near a nuclear power enterprise (NPE). Altogether 38124 infants born in 1950-1978, were investigated. The dead infants (1160) were divided into 3 groups with relation to their parents' place of work: 1--infants whose parents worked in the NPE; 2--infants whose parents worked in town factories and offices; 3--all infants in the town. The total doses of gamma-irradiation for mothers were 10-400 cSv, those for fathers--30-520 cSv, intrauterine irradiation of a fetus was 0.5-55 cSv. The individual effective equivalent dose of irradiation of the residents of the town was 17.3 cSv over 40 years. Occupational gamma-irradiation of the parents at doses exceeding the maximum permissible ones in the first 10 years of work at the NPE made no effect on the mortality rates in infants of the first generation. Differences in the mortality rates from the same causes were determined by socioeconomic factors.
