Micro-mapping of terrestrial gamma radiation dose (TGRD) at meter grid spacing in and around four urban homes in Miri City shows rates ranging from 70 to 150 nGy/h. Tiled surfaces (floors and walls) vary between properties and have a clear and significant influence on TGRD which is highest in kitchens, washrooms and toilets. Application of a single indoor value for annual effective dose (AED) may lead to underestimations of up to 30%. The AED is unlikely to exceed 0.8 mSv in homes of this type in Miri, which is within recommended guidelines.
在美里市四个城市家庭及其周边以米网格间距对陆地伽马辐射剂量（TGRD）进行的微观测绘显示，剂量率范围为70至150纳戈瑞/小时。不同房产的瓷砖表面（地板和墙壁）存在差异，且对TGRD有明显且显著的影响，在厨房、洗手间和卫生间中TGRD最高。采用单一的室内年有效剂量（AED）值可能导致高达30%的低估。在美里这种类型的家庭中，AED不太可能超过0.8毫希沃特，这在推荐指南范围内。
