An analysis of the health effects of the Chernobyl disaster on children in Kaluga region to develop the strategy and tactics of specialized medical examination

Author: M.P. Borovikova

Reference: Dissertation, Doctor of medical sciences, Obninsk, 2004

Keywords: leukemia, solid cancer, categorization, long term analyses

Abstract:

1. The world’s first radiation accident after the accident at the Chernobyl nuclear power plant with the fallout over large areas of radionuclides of iodine and cesium, etc. (with a density of pollution in the Kaluga region up to 15 Ci/km2) was implemented at the district level of the Russian State Medical Dosimetry Registry scientifically grounded Specialized medical examination of the child population, for the analysis of individual and summary measures of health.
2. Population analysisv was carried out in the Kaluga region and the calculation of attributable risk of stochastic effects. It is shown that the lifetime risk for thyroid cancer in children was 8.25, leukemia – 1.38 and 0.75 solid cancers per 100 patients.
3. Scientifically proven lack of dependence of intense growth in overall incidence of newly diagnosed and individual classes in its structure from the value of the mean cumulative effective dose to the whole body for the first 10 years of living children in the contaminated areas of the Kaluga region.
4. Based on analysis of the demographic-epidemiological and standardized intensive indicators of newly diagnosed disease, in the dynamics between 5 and 15 years, four risk groups are defined to follow-up with intact identification of possible long-term effects of low doses of radiation.

The assessment of individual doses of thyroid cancer of the population of Kaluga region as a result of direct effects of the Chernobyl accident, methodical and programmatic explanation

Author: E.K. Yaskova

Reference: Dissertation, candidate of biology, Obninsk, 2001

Keywords: exposure dose

Abstract: Review of this literature shows that, although 15 years have passed since the Chernobyl accident, the problem of adequate assessment of the level of exposure of the thyroid with radioactive iodine in the population living in the territory of the former USSR, is still quite urgent. This explains the large flow of scientific publications, presentations and discussions on this subject in recent years, as correct assessment of the initial dose-step in addressing many of the medical, epidemiological, social and other problems. In the Kaluga region the initial dose assessment was made in 1986 immediately after the primary direct measurements collected as a result of radiological survey of the population in May of the same year. In the absence of reliable information about the required environmental parameters of the formation of exposure, dose calculation was carried out by a conservative scheme based on the following assumptions: a single fallout on April 27, the earliest starting date of grazing (until April 27), the presence of countermeasures, from May 10 .. .. The aim of this work – revaluation of individual thyroid doses to the population of the surveyed areas of Kaluga region, taking into account new data on factors of the formation of exposure.

Comparative assessment of indicators of overall level and patterns of disease with cytogenetic indices in children and adolescents living in the contaminated areas of the Kaluga Region after the accident of the Chernobyl nuclear power plant

Author: N.O. Omapaskhabov

Reference: Dissertation, 2007

Keywords: demography, somatic abnormalities, digestive system

Abstract: For the first time, a comprehensive comparative evaluation is carried out of the dynamics of demographic indicators, indicators of the overall level and structure of newly diagnosed disease, as well as cytogenetic indices in child population living for 20 years in the contaminated areas following the accident of the Chernobyl nuclear power plant. Implements, in the initial -“iodine”- period of the Chernobyl accident, direct measurements of absorbed doses of the thyroid gland (TG) in children of Zhizdra area, allowing, for the first time, to evaluate the observed functional changes in the thyroid depending on the individual doses of incorporated radionuclides of iodine. Determines the role of cytogenetic damage in the development of somatic abnormalities in children with elevated levels of chromosomal aberrations. Especially in prenatally irradiated cases, morphological and functional changes in the thyroid gland diseases in the respiratory and digestive system, are more often encountered. The results obtained in general: Materials of the research formed the basis for the planning of socio-economic measures and medical administration of the Kaluga region in the contaminated areas after the Chernobyl accident …
