Abstract In the recent past, remarkable progresses has been made in radon epidemiological investigation for human populations, with the radon-induced excess relative risk being 0.16%/100 Bq m-3.It should be noted, for implementing radon action standards, that the action levels are differently implicated for population dwellings and workplaces.The dose limits and the derived air concentration are provided for the individuals, both of which can not be used as the main basis for controlling workplaces (sources).The controlling of radon concentrations should be based primarily on radiation protection optimization and constraints.
