   <abstract xml:lang="ru">
    <p>Цель: Оценка влияния малых доз диагностического облучения при проведении компьютерной томографии на развитие канцерогенных эффектов у населения г. Озёрск&#13;
Материал и методы: Описаны результаты анализа данных радиационно-эпидемиологического регистра, созданного в лаборатории радиационной эпидемиологии Южно-Уральского института биофизики г. Озёрска. Регистр содержит информацию о 26 626 рентгенологических обследованиях жителей г. Озёрска всех возрастных групп, включая детей до 1 года, проходивших диагностику при помощи компьютерной томографии в медицинских учреждениях Челябинской области за период с 1993 по 2018 гг. &#13;
Результаты: На основании проанализированной медико-дозиметрической информации оценены шансы возникновения злокачественных новообразований среди пациентов, подвергавшихся диагностическому облучению при проведении рентгеновской компьютерной томографии с учётом наличия основных радиационных и нерадиационных факторов (пол, достигнутый возраст, наличие контакта с профессиональным облучением, количество обследований методом КТ, величина накопленной эффективной дозы и DLP).&#13;
Заключение: В когорте жителей г. Озёрска, подвергавшихся воздействию малых доз диагностического облучения при компьютерной томографии, получено статистически значимое влияние пола и возраста на шансы возникновения злокачественного новообразования, диагностированного не ранее, чем через 2 года после обследования. Также, обнаружена значимая связь эффективной дозы от диагностического облучения на КТ и вероятностью последующего развития рака. Вместе с этим, как для населения, так и для персонала ПО «Маяк» величина DLP статистически значимо не повышала шансы развития злокачественного новообразования в исследуемой когорте.</p>

    <p>Purpose: To assess the contribution of low doses of diagnostic radiation due to computed tomography to carcinogenic risk among population of Ozersk.&#13;
Material and methods: The study describes the results of the analysis of data from the radiation-epidemiological register created in the laboratory of radiation epidemiology of the Southern Urals Biophysics Institute of Ozersk. The register contains information on 26,626 CT examinations of Ozersk residents of all age groups, including children under 1 year old, carried out in medical departments of the Chelyabinsk region during the period from 1993 to 2018.&#13;
Results: Based on the analyzed medical and dosimetric information from the CT Register database, the chances of malignant neoplasms among patients exposed to diagnostic irradiation during computed tomography were assessed taking into account the presence of the main radiation and non-radiation factors (age, sex, occupational exposure, number of CT examinations, effective dose and DLP).&#13;
Conclusion: In a cohort of Ozersk residents who were exposed to low doses of diagnostic radiation during computed tomography, a statistically significant effect of sex and age attained to malignant neoplasm was obtained. Also, a significant relationship was found between the effective dose from diagnostic CT and the likelihood of subsequent cancer development diagnosed no earlier than 2 years after the first CT examination. At the same time, the DLP did not statistically significantly increase the chances of developing a malignant neoplasm in the study cohort for both the population and the personnel of the Mayak PA.</p>
