THE ANALYSIS OF 2002-2024 DEATH CAUSES IN INDIVIDUALS EXPOSED TO PROLONGED IONIZING RADIATION
The study is aimed to analyze the death causes of the population exposed to prolonged ionized radiation due to living near the Semipalatinsk nuclear test site.
Materials and methods of the study. The initial information for creating the cohort was the data of the study implemented in 1998-2002 with 3539 randomly selected individuals affected by the Semipalatinsk Nuclear Test Site. For each cohort member having the vital status “Dead” the date and cause of the death are verified.
Results. The studied cohort included 50.6% men and 49.4% women. The main causes of death of residents of villages exposed to prolonged exposure to ionizing radiation were diseases of the circulatory system - 54.7%; neoplasms - 20.7%; respiratory diseases - 7.1%. Life expectancy was higher in women than in men, however, did not differ depending on nationality, and differed statistically significantly depending on the area of residence. The frequency of circulatory system diseases as a cause of death was higher in residents of areas with extreme, maximum and increased radiation risk compared to residents of areas of minimum radiation risk.
Our research demonstrates the need of further study of the correlation of mortality and diseases of circulation system and cancer and prolonged exposure to radiation as a result of living near Semipalatinsk Nuclear Test Site.
Key words: Semipalatinsk nuclear test site, areas of radiation risk, mortality, death causes.
