Proposals for inclusion in NRB-2019 Section on radiogenic risk

Abstract

In this article it made analysis of concepts and values used in NRB-99/2009 and a number of national methodological documents on the assessment of risks associated with irradiation. It is concluded that NRB-99/2009 violates the logic in the presentation of this issue. It can be restored if a special section is introduced in the developed NSB-2019, with more detailed coverage of the terminological and methodological aspects of the assessment of such risks. The draft section is attached to this article In the draft introduces a number of new terms (radiogenic risk, nominal radiogenic risk, radiogenic risk of death from cancer and radiogenic risk of cancer and a number of others) with a clear interpretation of their meaning and purpose, as well as the sphere application of the relevant values. The draft proposes to replace the term generalized risk with radiation risk, which is more in line with its meaning. Given also specific formulas to calculate the radiogenic risk coefficients for different types of irradiation based on the real demographics data for exposed populations. Because of the cumbersome formulas, they can be given to the Annex of the NRB-2019 or issued in methodical instructions prepared in the elaboration of the provisions of the NRB-2019.
