This paper describes measurements of indoor gamma radiation dose in At-Taif city, Kingdom of Saudi Arabia. CaSO(4):Dy thermoluminescence dosemeters were used for the detection of gamma radiation in 250 houses within the city. The values of indoor gamma radiation dose rate measured ranged between 90 and 221 nGy h(-1) for the time interval from September 2002 to September 2003. The measured dose varied with the type of house and season of the year. The highest average value 192 +/- 7 nGy h(-1) was measured inside apartments made of cement and brick (157-221 nGy h(-1)), and the lowest average value 92 +/- 6 nGy h(-1) in mud houses (58-117 nGy h(-1)). Intermediate values 154 +/- 5 nGy h(-1) (128-177 nGy h(-1)) and 167 +/- 9 nGy h(-1) (144-185 nGy h(-1)) were observed in large halls and villas, respectively. The average indoor gamma radiation dose rate received by the population of At-Taif city is 138 nGy h(-1) and its corresponding annual dose is 1211 muGy y(-1). The calculated mean effective dose to At-Taif city population, assuming an indoor occupancy factor of 80%, is 970 muSv y(-1).
本文描述了沙特阿拉伯王国塔伊夫市室内伽马辐射剂量的测量情况。使用硫酸钙：镝热释光剂量计对该市250所房屋内的伽马辐射进行检测。在2002年9月至2003年9月的时间段内，所测量的室内伽马辐射剂量率值在90至221纳戈瑞每小时之间。测量的剂量随房屋类型和一年中的季节而变化。在由水泥和砖块建造的公寓内测得的最高平均值为192±7纳戈瑞每小时（157 - 221纳戈瑞每小时），在土坯房内测得的最低平均值为92±6纳戈瑞每小时（58 - 117纳戈瑞每小时）。在大厅和别墅中分别观察到中间值154±5纳戈瑞每小时（128 - 177纳戈瑞每小时）和167±9纳戈瑞每小时（144 - 185纳戈瑞每小时）。塔伊夫市居民所接受的室内伽马辐射剂量率平均值为138纳戈瑞每小时，其相应的年剂量为1211微戈瑞每年。假设室内居住因子为80%，计算得出塔伊夫市居民的平均有效剂量为970微希沃特每年。
