Diffusive sampling of radon

Information required for the design and testing of diffusive samplers for radon is scattered across numerous disciplines, making it difficult to use. To aid future research, a multidisciplinary review is given addressing the following: 1) the differential equations describing mass transfer in a radon diffusive sampler; 2) mathematical procedures for solving these equations; 3) the physical parameters defining the adsorbent in the diffusive sampler; and 4) a standardized protocol for validating the performance of diffusive samplers for radon.
