Risk bases can complement dose bases for implementing and optimising a radiological protection strategy in urgent and transition emergency phases.

Risk bases can complement dose bases for implementing and optimising a radiological protection strategy in urgent and transition emergency phases. Radiat Environ Biophys. 2019 Jul 25;: Authors: Walsh L, Ulanowski A, Kaiser JC, Woda C, Raskob W Abstract Current radiological emergency response recommendations have been provided by the International Commission on Radiological Protection and adopted by the International Atomic Energy Agency in comprehensive Safety Standards. These standards provide dose-based guidance for decision making (e.g., on sheltering or relocation) via generic criteria in terms of effective dose in the range from 20 mSv per year, during transition from emergency to existing exposure situation, to 100 mSv, acute or annual, in the urgent phase of a nuclear accident. The purpose of this paper was to examine how such dose reference levels directly translate into radiation-related risks of the main stochastic detrimental health effects (cancer). Methodologies, provided by the World Health Organization after the Fukushima accident, for calculating the lifetime and 20 year cancer risks and for attributing relevant organ doses from effective doses, have been applied here for this purpose with new software, designed to be available for use immediately after a nuclear accident. A new feature in this software is a comprehensive accounting for uncertainty via simulation technique, so that the risks may now be presented wi...
