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.
通过扩散方程得出了室内220Rn原子的分布情况。根据混凝土墙中220Rn的析出率,获得了212Pb和212Bi的活度浓度。在某些情况下,靠近混凝土墙表面时,吸入220Rn衰变产物所导致的辐射暴露可能相当可观。
