Данная когорта объединяет лиц, облученных в возрасте до 20 лет в результате двух радиационных аварий на Производственном Объединении «Маяк» на Южном Урале (сбросы радиоактивных отходов в реку Течу и образование Восточно-Уральского радиоактивного следа). Численность когорты для анализа заболеваемости солидными злокачественными новообразованиями составила 31 578 человек. Все члены подверглись постнатальному облучению, а некоторые – и внутриутробному. У части из них родители были облучены до зачатия. С 1956 по 2018 г. на территории наблюдения за заболеваемостью было зарегистрировано 2018 случаев заболеваний солидными злокачественными новообразованиями, число человеко-лет составило 818 083. Анализ проведен методом Пуассоновской регрессии с использованием простой параметрической модели избыточного относительного риска. Доверительные интервалы c 95% достоверностью оценены с помощью метода максимального правдоподобия. В первом анализе риска заболеваемости солидными злокачественными новообразованиями у членов данной когорты использована только постнатальная доза, при этом учтен факт преконцептивного облучения родителей. Средняя постнатальная доза на желудок, накопленная за весь период наблюдения у членов когорты, включенных в анализ заболеваемости, рассчитанная по дозиметрической системе TRDS-2016, составила 0,047 Гр. Анализ показал линейную зависимость избыточного относительного риска заболеваемости солидными злокачественными новообразованиями от постнатальной дозы. При 5-летнем латентном периоде избыточный относительный риск составил 0,66/Гр, р=0,006. При оценке избыточного относительного риска в разных возрастных группах на начало облучения значимая величина риска сохранилась только в возрастной группе до 1 года на начало облучения, равная 2,16/Гр, р&lt;0,02. Данные результаты согласуются с результатами анализа риска солидных злокачественных новообразований в когорте внутриутробно облученных на реке Тече, в которой был выявлен статистически значимый избыточный относительный риск от постнатальной дозы, а также с результатами анализа риска в японской когорте облученных внутриутробно и в раннем детстве.</p></abstract><trans-abstract xml:lang="en"><p>The aim of this work is to assess the radiogenic risk of solid cancers incidence in the members of the Urals Childhood Exposure Cohort. The cohort includes people exposed under 20 years of age as a result of two radiation accidents at the Mayak Production Association in the Southern Urals (discharges of radioactive waste into the Techa River and the formation of the East Ural radioactive trace). The number of the cohort for solid cancer incidence analysis is 31,578 individuals. All the members were postnatally exposed and some of them – in-utero. Some of their parents were exposed before conception. 2,018 solid cancers were registered on the incidence catchment area during the period 1956-2018, the total amount of person years was 818,083. The analysis was carried out by the Poisson regression method with a simple parametric excess relative risk model. 95% confidence intervals were estimated with maximum likelihood approach. Only a postnatal dose was used in the first solid cancer incidence analysis of this cohort members with due account for preconception exposure of parents. TRDS-2016 mean postnatal dose accumulated over the entire follow-up period in the stomach of cohort members was 0.047 Gy. The analysis showed linear dependence of solid cancer incidence excess relative risk on postnatal dose. Excess relative risk was 0.66/Gy, р=0.006 with a five-year latency period. While estimating excess relative risk in different age groups at the beginning of exposure, a significant risk was present only in the age group under 1 year and amounted to 2.16/Gy; р&lt;0.02 at the onset of exposure. The present results are in agreement with the results of the solid cancer incidence risk analysis both in the Techa River Cohort of exposed In-Utero where a statistically significant excess relative risk from a postnatal dose was revealed, and with the results of risk analysis in the Japanese cohort of people exposed in-utero and in early childhood.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Уральская когорта облученных в детстве</kwd><kwd>река Теча</kwd><kwd>Восточно-Уральский радиоактивный след</kwd><kwd>радиогенный риск</kwd><kwd>заболеваемость солидными злокачественными новообразованиями</kwd><kwd>избыточный относительный риск</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Urals Childhood Exposure Cohort</kwd><kwd>the Techa River</kwd><kwd>East Urals radioactive trace</kwd><kwd>radiogenic risk</kwd><kwd>solid cancer incidence</kwd><kwd>excess relative risk</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках реализации федеральной целевой программы «Обеспечение ядерной и радиационной безопасности на 2016–2020 годы и на период до 2030 года».</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">UNSCEAR 2013.
