Abstract

The deposition velocity of radon progeny is used to model the removal of progeny from the air by surfaces in assessing indoor air quality. It can also be used to assess radon-induced background in sensitive, low-background experiments. A single value of the deposition velocity is typically used for all radon progeny for modeling purposes. This paper presents a method for uniquely determining the individual deposition velocities of radon progeny. Measurements demonstrating the method were carried out.
