Abstract

For more accurate assessment of the enhanced external exposure to dwellers caused by decorative stones, based on a model room and different decorative conditions, the 3-D distributions of indoor gamma dose rates were computed by the Monte Carlo simulations, and a new model was established to estimate the extra gamma dose rate at the centre of the room in this study. For verification of the simulation results, the gamma radiation was both instantaneously and cumulatively measured in a test room. The results showed that both the gamma dose rate at the centre of the room and the distribution of indoor gamma radiation were in general agreement with the simulated ones.
