The aim of the work is to assess the risk of morbidity of the population of the Kaluga, Bryansk and Oryol regions with thyroid cancer at the level of individual settlements based on experimental data. The iodine content in soils and vegetation cuttings of pastures in geochemically contrasting landscapes, as well as in cows' milk and potatoes of private household farms in the regions affected by the Chernobyl accident in 1986: Bryansk (2021), Oryol (2022) and Kaluga (2023) regions was studied. Joint expeditions of the Laboratory of Environmental Biogeochemistry of GEOKHI RAS and the Department of Human Ecology and Bioelementology of the Institute of Ecology of RUDN, carried out on the initiative and with the participation of the authors, revealed a significant variation of iodine concentration in soils and food products, which may be crucial for assessing the risk of thyroid diseases, including thyroid cancer, among the local rural population. The iodine content was found to be highly variable in both topsoil (0.31-3.04 mg/kg) and grass cuttings (0.14-0.29 mg/kg) of the study area. The maximum natural and technogenic risk of thyroid cancer morbidity in the rural population as a result of the consequences of the Chernobyl accident of 1986 is specific for the studied settlements of Zhizdrinsky district of Kaluga region, Bolkhovsky, Dmitrovsky and Sverdlovsky districts of Oryol region, Rognedinsky district of Bryansk region.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Природный дефицит йода, в некоторых регионах России, провоцирующий заболевания щитовидной железы, усугубляет последствия поступления в пищевые цепи короткоживущих радиоактивных изотопов этого элемента вследствие аварии на Чернобыльской АЭС (1986). Цель работы - оценка риска заболеваемости населения Калужской, Брянской и Орловской областей раком щитовидной железы на уровне отдельных населенных пунктов на основе экспериментальных данных. Исследовано содержание йода в почвах и укосах трав пастбищ - геохимически контрастных ландшафтов, а также в молоке коров и клубнях картофеля личных подсобных хозяйств в пострадавших при аварии на ЧАЭС 1986 г. областях: Брянской (2021 г.), Орловской (2022 г.) и Калужской (2023 г.). Совместные экспедиции лаборатории биогеохимии окружающей среды ГЕОХИ РАН и департамента экологии человека и биоэлементологии института экологии РУДН им. Патриса Лумумбы, проведенные по инициативе и при участии авторов, выявили значительное варьирование концентрации йода в почвах и продуктах питания, что может иметь решающее значение при оценке риска распространения заболеваний щитовидной железы, в том числе рака среди местного сельского населения. Установлено, что содержание йода варьировало в широких пределах как в верхних слоях почв (0,31-3,04 мг/кг), так и в укосах трав (0,14-0,29 мг/кг) исследуемой территории. Наибольший природно-техногенный риск заболеваемости сельского населения раком щитовидной железы в результате последствий аварии на ЧАЭС характерен для обследованных населенных пунктов Жиздринского района Калужской области, Болховского, Дмитровского и Свердловского района Орловской области, Рогнединского района Брянской области.</p></trans-abstract><kwd-group xml:lang="en"><kwd>iodine</kwd><kwd>pasture soils</kwd><kwd>Bryansk Region</kwd><kwd>Oryol Region</kwd><kwd>Kaluga Region</kwd><kwd>thyroid diseases</kwd><kwd>agricultural products</kwd><kwd>radionuclides</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>йод</kwd><kwd>почвы пастбищ</kwd><kwd>Брянская область</kwd><kwd>Орловская область</kwd><kwd>Калужская область</kwd><kwd>заболевание щитовидной железы</kwd><kwd>сельскохозяйственная продукция</kwd><kwd>радионуклиды</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was carried out under the state order of the Laboratory of Environmental Biogeochemistry of the Geochemical Institute of the Russian Academy of Sciences, with the participation of specialists from the Institute of Ecology of the Peoples’ Friendship University of Russia named after Patrice Lumumba, supported by Research No. 202726-0-000 “Radiation safety of food products of plant and chicken origin”.</funding-statement><funding-statement xml:lang="ru">Работа выполнена по государственному заданию лаборатории биогеохимии окружающей среды ГЕОХИ РАН, при участии специалистов института экологии РУДН им.
