摘要
由于缺乏专用于建筑材料的剂量模式,目前国际上普遍采用室外土壤的剂量模式来计算建材的辐射剂量。本论文用MonteCarlo方法得到几类装饰材料的辐射剂量模式。由该模式计算出的空气吸收剂量率与实测数据一致。而用土壤的剂量模式算出的空气吸收剂量率与实测数据相差很远。因此,建筑装饰材料不能近似采用室外土壤的辐射剂量计算模式。
In the past, the radiological dose model for soil (the soil's dose model) was used to calculate the doses of decorative building materials, because no model suited to these materials was established. With the help of Monte Carlo method, we have proposed a new model to calculate the absorbed dose rates in air for decorative building materials. Values calculated by the new dose model, though much diverse from those by the soil's dose model, are very close to the measured values. It is therefore concluded that the soil's dose model is usually not suitable for estimating radiological doses from decorative building materials.
