Abstract:
An investigation of the performance of a diffusion barrier, charcoal-based 222Rn monitor under several artificial environmental conditions showed that both temperature and relative humidity levels affect 222Rn uptake. A physical model was developed adequately describing the temperature effects, while an empirical model was used to summarize the combined effects of temperature and atmospheric water concentration.
