To assess the population dose due to the natural background radiation around the upcoming Kudankulam nuclear power plant, a systematic investigation has been carried out by measuring the indoor gamma dose. In total, 159 dwellings have been selected around the Kudankulam nuclear power plant area i.e. in Radhapuram and Nanguneri taluk (sub-districts) for the measurement. The geometric mean value of indoor gamma dose rate is 305 +/- 48 nGy h(-1) and 273 +/- 50 nGy h(-1) in Radhapuram and Nanguneri taluks (sub-districts), respectively. The annual effective dose due to indoor gamma radiation to the population has been found to be 1.5 mSv and 1.36 mSv in Radhapuram and Nanguneri taluks, respectively.
为评估即将建成的库丹库拉姆核电站周边天然本底辐射所致的公众剂量，通过测量室内伽马剂量开展了一项系统调查。总共在库丹库拉姆核电站区域周边，即拉贾普拉姆和南古内里乡（分区）选取了159处住宅进行测量。拉贾普拉姆和南古内里乡（分区）的室内伽马剂量率几何平均值分别为305±48纳戈瑞每小时和273±50纳戈瑞每小时。已发现拉贾普拉姆和南古内里乡居民因室内伽马辐射所致的年有效剂量分别为1.5毫希沃特和1.36毫希沃特。
