Radon dose conversion coefficients and their use in the Nordic countries
The dose conversion coefficients for radon published by the ICRP in 20181 caused some puzzlement among many radiation protection authorities, as doses for the same radon exposure would be twice as high, and in some cases even higher. This may lead to an increased number of workplaces being considered as a planned exposure situations and requiring a safety license under the EU-BSS directive. Furthermore, the credibility of the authority may suffer in the eyes of those workplaces with elevated radon levels if a concentration level previously considered safe enough is no longer acceptable. A further complication factor is that the ICRP and UNSCEAR each have their own, different dose conversion coefficients.
