Abstract
<jats:p>The aim of this study is to conduct a comparative analysis of the relative risk of morbidity among children living in areas where nuclear power plants (NPP) with HPCR – high-power channel reactor and WCPR – water-cooled power reactor are located. Research materials and methods. Data on the incidence of disease among children aged 0-14 years in the satellite towns of NPPs No. 1 and No. 2 with HPCR and NPPs No. 3 and No. 4 with WCPR were analyzed. The study materials are medical statistics data from the federal statistical observation form No. 12 “Information on the number of diseases registered in patients living in the service area of a medical organization”. Research results and their analysis. It was found that the total relative risk of morbidity among children living near nuclear power plants with HPCR-type and WCPR-type reactors is not significantly different: ΣRRHPCR/WCPR=14.92 and ΣRRWCPR/HPCR=14.80, therefore the relative risk is RRHPCR/WCPR=1.01. Despite lower values for the total relative radiation risk of morbidity (ΣRRHPCR/WCPR=5.30; ΣRRWCPR/HPCR=6.10), its share in the total relative risk among children in satellite towns of nuclear power plants with WCPR is higher than among children in towns hosting nuclear power plants with WCPR – 28.0% and 26.2%, respectively, which does not affect the overall assessment of morbidity among the child population, which corresponds to the average indicators for the Russian Federation. Therefore, it has been found that radiation is not a leading factor affecting the health of children in cities near nuclear power plants, and that childhood morbidity rates correspond to data for the country as a whole.</jats:p>
