Установлены достоверные различия в удельном содержании калия в тканях организма по таким критериям, как место жительства, проживание на момент аварии на ЧАЭС, возраст, пол. Из них наиболее значимыми и определяющими признаны возраст и пол. Созданы линейные регрессионные модели, описывающие накопление 40 K в организме жителей района в зависимости от возраста и пола. Обнаружено, что моделирование возрастзависимого содержания 40 K показывает лучшие результаты при предварительном разделении популяции по гендерному признаку.</p></abstract><trans-abstract xml:lang="en"><p>The incorporation of 40 K in the body of residents of the Luninets district of the Brest region was studied based on the results of 58809 measurements on a human radiation spectrometer for the period from 2016 to 2020. Significant differences were established in the specific content of potassium in body tissues according to such criteria as place of residence, residence at the time of the Chernobyl accident, age, gender. Of these, age and gender are recognized as the most significant and determining. Linear regression models have been created that describe the accumulation of 40K in the body of residents of the area, depending on age and gender. It was found that modeling the age­dependent content of 40 K shows the best results with a preliminary separation of the population by gender.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>калий</kwd><kwd>возраст</kwd><kwd>пол</kwd><kwd>моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>potassium</kwd><kwd>age</kwd><kwd>gender</kwd><kwd>modeling</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Сенатов, В.
