Measurements of the concentration of radon in the environment using charcoal canisters were first described by George, and these canisters have become the Environmental Protection Agency standard. A calibration factor (CF), relating the detected activity A of the radon daughter {sup 214}Bi within the canister to the radon concentration in air C{sub R}, has been defined by Watson et al. The purpose of this paper is to examine a kinetic model for the adsorption of radon on a charcoal canister in humid air and to compare its predictions for the dependence of the CF on water mass gain and exposure time with the dependence measured by Watson.
