ABSTRACT
OBJECTIVE: Analysis of information from various sources for its use in epidemiological study on mortality of people (born in 1968-1986) who were children and adolescents at the time of the Chornobyl accident. OBJECT OF STUDY: Information and statistical sources for 1986-2011 on mortality among people who were children and adolescents at the time of the Chornobyl accident and lived on the most radioactive contaminated territories (RCT) of Ukraine (Ivankiv and Polisske regions of Kyiv oblast, Narodychi and Ovruch regions of Zhytomyr oblast). RESEARCH METHODS: theoretical, general scientific, documentary analysis, demographic. RESULTS AND CONCLUSIONS: The study is to determine the suitability of available information and statistical support for measuring and assessing mortality of people exposed in childhood as a result of the Chornobyl accident and liv ing in contaminated areas of Ukraine. A combination of information and statistical data provided by SRU, Ministry of Justice of Ukraine, State Statistics Service (SSS) of Ukraine and NNCRM makes it possible to successfully conduct retrospective cohort studies in any area and for any period.

OBJECTIVE: Appraisal of trends in structure of characteristics in population of radiologically contaminated territo ries (RCT) born in 1968-1986 (children and adolescents at the time of the ChNPP accident).Study Object. Persons born since 1968 till 1986 i.e. children and adolescents at the time of the ChNPP accident, who lived on the most intensively contaminated territories of Ukraine (Ivankiv and Poliske regions of Kyiv oblast and Narodichi and Ovruch regions of Zhytomyr oblast) within 1986-2011. MATERIALS AND METHODS: The State Service of Statistics of Ukraine was a principal information base of the study. Specifically the statistical report forms R 11 «Distribution of residential population by gender and age in yearly intervals at a turn of the year¼ and A 1 «General totals of natural population development¼ were retrieved. Survey was conducted for the period of 1986-2012. Mathematical, statistical, demographic and software technological methods were applied. RESULTS AND CONCLUSIONS: Summarization of statistical data on population size, both with its gender and age pat terns in the most intensively contaminated territories of Ukraine, namely in Ivankiv and Poliske regions of Kyiv oblast and Narodichi and Ovruch regions of Zhytomyr oblast resulted in conclusion of 27,200 people living there who were born in 1968-1986. They are a critical group of the ChNPP accident survivors. At the beginning of 1987 the male generations of the same age were present in more even manner (4.53-5.82 %%) vs. females (3.04 6.02 %%). No significant change both in gender and year of birth was found in 2012 vs. 1987. Change in gender proportion in surveyed population within 1986 2011 requires some more precise evaluation.
