    <p>Цель: Сравнительный эпидемиологический анализ радиогенного риска заболеваемости злокачественными новообразованиями работников, начавших свою трудовую деятельность в разные периоды деятельности ПО «Маяк».&#13;
Материал и методы: Для анализа заболеваемости злокачественными новообразованиями (без учета раков легкого, печени и скелета – органов основного депонирования плутония) выбрана когорта работников ПО «Маяк», нанятых на реакторы, радиохимический завод и завод по производству плутония, а также на ремонтно-механический завод и завод по водоподготовке в 1948–1982 гг., а в качестве субкогорт сравнения 1948-1958 гг. и 1959-1982 гг. найма.&#13;
В работе использованы регрессионные модели относительного риска, включающие описание показателей фоновой заболеваемости и избыточный радиогенный риск. &#13;
Результаты: Оценка радиогенного риска на единицу дозы внешнего гамма-облучения в субкогорте 1948–1958 годов найма (ИОР/Гр: 0,11; 95 % ДИ: 0,02; 0,21) оказалась близка к оценке, полученной для всей когорты в предыдущих исследованиях.&#13;
В субкогорте 1959–1982 гг. найма точечная оценка ИОР/Гр была в 3 раза выше, чем в субкогорте 1948–1958 гг. найма, но оказалась статистически незначима для всего диапазоне доз в целом. Ограничение данных дозами до 2 Гр позволило получить статистически значимую оценку ИОР/Гр при использовании линейной зависимости (0,45; 95% ДИ: 0,04; 0,95), которая в 4 раза превышает оценку ИОР/Гр для первой субкогорты, полученную при аналогичных ограничениях (0,11; 95 % ДИ: –0,01; 0,25). &#13;
Все межкогортные различия были статистически незначимыми, и об отличиях можно говорить только при описании точечных оценок.</p>

    <p>Purpose: comparative epidemiological analysis of cancer incidence rates among PA Mayak workers hired at different calendar periods.&#13;
Material and Methods:  The cohort of PA Mayak workers hired at reactors, radiochemical, plutonium, water preparing and repair plants in 1948-1982 was selected for analysis of solid cancer (except lung, liver and bone) incidence. The cohort was divided into two subcohorts 1948-1958 and 1959-1982 years of hire.&#13;
Regression models of relative risk included the description of background rates and excess radiation risk was used. &#13;
Results: The radiation relative risk per 1 Gy was (ERR/Gy: 0.11; 95 % CI: 0.02; 0.21) in the subcohort of workers hired in 1948–1958 and was close to the estimates from previous studies for the whole cohort.&#13;
In the subcohort of workers hired in 1959–1982 the point estimate of ERR/Gy was 3 times higher than in the subcohort 1948–1958 years of hire, but it was not statistically significant in the whole dose range. Restriction of doses up to 2 Gy allowed to get significant estimate of ERR/Gy (0.45; 95 % CI: 0.04; 0.95), which 4 times higher the estimate in the first subcohort calculated with the same restriction (0.11; 95 % CI: -0.01; 0.25). &#13;
All subcohorts differences were not statistically significant and we can say about point distinctions only.</p>
