title: Indoor concentrations of 220Rn and its decay products.
abstract: The distribution of 220Rn atoms in a room was derived from the diffusion equation. The activity concentrations of 212Pb and 212Bi were obtained in relation to 220Rn exhalation rate from a concrete wall. Near the surface of the concrete wall, the radiation exposure due to inhalation of 220Rn decay products may be significant in some cases.
