Исследование влияния неопределённости доз облучения на Прогноз радиационных рисков солидных раков по моделям МКРЗ для российских популяций при однократном облучении

Abstract

Исследовано влияние статистического разброса (неопределённости) доз облучения, а так же фактора эффективности дозы и мощности дозы (DDREF) на прогноз радиационных рисков солидных раков по моделям МКРЗ для российских популяций при однократном облучении. Показано, что средние значения прогнозируемых радиационных рисков смещаются при учёте источников разброса. Наибольшее значение при прогнозировании радиационных рисков имеет учёт статистического разброса фактора DDREF. Учёт различных источников статистического разброса, включая фактор DDREF при его среднем значении DDREF=2, может привести к 6-кратному снижению среднего значения прогнозируемого риска солидных раков. Этот факт так же может быть следствием плохой адаптации моделей риска МКРЗ к российским популяциям (следствием существенного различия прогнозных значений, вычисленных по моделям EAR и ERR, для российских популяций).

Impact of statistical dispersion of radiation dose values, as well as dose and dose rate effectiveness factor (DDREF) on prognosis of radiation risks calculated with ICRP models for Russian population after single exposure to radiation is discussed in the article. Mean values of predicted radiation risks are shown to be biased if sources of the dispersion are taken into account. The main source of uncertainty is DDREF. Calculation of different sources of statistical dispersion including DDREF with its mean value 2.0, may result in 6-fold reduction of mean value of predicted risk of solid cancers. Such effect may be caused by inappropriate adjustment of ICRP risk models to Russian population.
