THE CONVERSION OF EXPOSURES DUE TO RADON INTO THE EFFECTIVE DOSE TAKING INTO ACCOUNT THE EQUIVALENCE OF RISKS FROM SHORT- AND LONG-TERM EXPOSURES.

The theoretical basis for comparing risks from short- and long-term exposures is developed aiming at implementing long-term exposures into a unique and consistent system of radiation protection. Based on system-analytical considerations, the equivalence of population-averaged risk rates due to prolonged exposures and population-averaged lifetime risks due to short- term exposures is shown. The consequences of this risk analysis are discussed, focussing on long-term exposures due to residential radon. Equations for the dose conversion of exposures due to radon into the effective dose are derived.
