[Assessment of radiation risk of leukemia induction based on the analysis of the consequences of population irradiation in Southern Ural]. / Otsenka radiatsionnogo riska induktsii leikoza na osnovanii analiza posledstvii oblucheniia naseleniia na Iuzhnom Urale.

The authors provide the results of long-term investigations of the consequences of environmental pollution from the military nuclear plant in the Southern Urals. Altogether 28,100 individuals who received substantial doses of external and internal radiation in the Techa riverside in the early fifties were entered into the study. The increase in the leukemia incidence as compared with unexposed controls has been confirmed on a statistical basis. The majority of excess cases of leukemia were recorded within the 5th to the 20th year after irradiation and may be attributed to the acute and chronic granulocytic types. The level of leukemia risk on the basis of the Techa river data is evaluated as 0.48-1.10 per 10(4) persons/years/Gy.
