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.
为了更准确地评估装饰石材对居住者造成的增强型外部照射，基于一个模型房间和不同的装饰条件，通过蒙特卡罗模拟计算了室内伽马剂量率的三维分布，并建立了一个新模型来估计本研究中房间中心的额外伽马剂量率。为了验证模拟结果，在一个测试房间对伽马辐射进行了即时和累积测量。结果表明，房间中心的伽马剂量率和室内伽马辐射分布总体上与模拟结果一致。
