Оценка коэффициентов радиационных рисков заболеваемости солидными раками мужского персонала Госкорпорации «Росатом» с учётом неопределённости доз профессионального облучения

Abstract

Получены оценки коэффициентов радиационных рисков заболеваемости солидными злокачественными новообразованиями мужского персонала Госкорпорации «Росатом» в зависимости от достигнутого возраста и предшествующей длительности работ с источниками ионизи­рующего излучения (длительности периода облучения). Показано, что для заданного достигнутого возраста коэффициенты риска растут с увеличением длительности предшествующего периода облучения. При учёте неопределённости доз облучения зависимость верхней 95% доверительной границы коэффициентов риска от длительности предшествующего периода облучения становится не монотонной. Для консервативной оценки радиационного риска заболеваемости солидными раками в исследуемой группе можно использовать коэффициент риска 0,090 на 1 Зв, а с учётом 15% неопределённости годовой дозы 0,096 на 1 Зв. С учётом коэффициента летальности случаев солидных раков для мужского населения России, коэффициенты радиационного риска смертности равны 0,045 на 1 Зв для консервативной оценки и 0,048 на 1 Зв для 15% неопределённости годовой дозы. Последнее значение в 1,17 раза превышает номинальный коэффициент риска, содержащийся в действующих российских Нормах радиационной безопасности.

Estimates of radiation risk coefficients of solid cancer incidence for the male personnel of the Rosatom State Corporation in dependence on the attained age and the previous duration of works with sources of ionizing radiation (duration of exposure period) are received. It is shown that for the given attained age, risk coefficients rise with increase in duration of previous exposure period. Allowing for dose uncertainty, dependence of the 95% upper confidential borders of risk coefficients becomes not monotonous. For a conservative assessment of radiation risk of solid cancer incidence in the studied group it is possible to use coefficient of risk 0,090 per 1 Sv, and allowing for 15% of uncertainty of an annual dose 0.096 per 1 Sv. Taking into account coefficient of a lethality of solid cancer cases for the male Russian population, coefficients of radiation risk of mortality are equal 0.045 per 1 Sv and 0,048 per 1 Sv, respectively. The last value by 1.17 times exceeds the nominal risk coefficient containing in the operating Russian Standards of radiation safety.
