Potential radiological risk for the population during implementation of the Rosatom Proryv project. Part 1. ICRP recommendations

The concept “radiation detriment” has been debated intensively in the pages of the ICRP Publication 103 (2007), new radiation epidemiological data obtained after 2007 have also been brought into discussion. For radiation detriment calculation radiation risk models based on data of the study of Japanese cohort of atomic bombings survivors were used. Models developed for estimating radiation risk factors take account of gender and age at exposure. Now ICRP has estimated radiation detriment in specially designed standard population by averaging the estimates based on age at exposure. The concept “radiation detriment” was developed for quantification of the overall harm to health of humans and their offspring from stochastic effects of low-level radiation on different parts of the body, reduction in life expectancy and reduced quality of life. In addition, radiation detriment is used to assess effective dose and its standardization for radiological protection. In the paper, the concept “radiation detriment” is assessed with regard to the possibility of extending the area of its application. The applicability of technique for calculation of radiation detriment is possible to be extended with account of Russian health and statistical data, lethality fraction estimates, years of life lost, gender and age. The extended “radiation detriment” will be renamed as “radiological detriment”, that will highlight the possibility of quantifying potential harm to a specific irradiated population. The magnitude of population-based radiological detriment may be used not only for matching sources of ionizing radiation by their impact on the standard population, but also for estimating the level of radiological protection of the specific population. The level of radiological detriment may be used for quantification of potential harm to the public health in the implementation of the Rosatom project “Proryv”.
