The radon factor
WebbThe dose conversion factor (DCF) which gives the relationship between effective dose and potential alpha energy concentration of inhaled short-lived radon decay products is calculated with a dosimetric approach. The calculations are based on a lung dose model with a structure that is related to the … WebbFactors Determining Concentration of Radon Indoors . Some of the factors that influence these concentrations indoors are the amount of primordial radionuclides present in the area, the distance of the indoor space from the source of radon gas; the difference in air pressure between the ground and the building.
