Cancer risks in the Kaluga oblast of the Russian Federation 10 years after the Chernobyl accident.

Cancer morbidity and mortality were studied in areas of the Kaluga oblast contaminated with radionuclides. The main objective of the study was to assess the influence of radiation exposure on existing levels of cancer morbidity and mortality. Time trends and relative population risks were analysed.

[Oncoepidemiologic situation in the Kaluga region of the Russian Federation ten years after the Chernobyl accident].

Cancer morbidity and mortality in radionuclide-contaminated areas of Kaluga Region have been investigated. The study was mainly concerned with the extent of radiation pollution influence on the present-day cancer morbidity and mortality rates. The correlations between the latter factors, on the one hand, and relevant population risks, on the other, have been analysed.

[Functional status of the pituitary-thyroid system in children and adolescents exposed to radiation as a result of the accident at the Chernobyl Nuclear Power Station].

The paper is concerned with the results of a follow-up over the period of 1986-1989 of function of the hypophyseo-thyroid system in children and adolescents (approximately 6000 persons), residing in the South-West of the Kaluga Region, where radiation fallouts were observed after the Chernobyl accident. The results were based upon the analysis of medical examinations and determination of the blood levels of TSH, T4 and T3. A certain functional activation of the thyroid system was observed in a majority of the examinees.
