在Kudankulam核电站周围的高本底辐射区，即Kanyakumari区的Agastheeswaram、thovalai taluks（分区），使用固态核径迹探测器测量了钍的浓度水平。已按季度周期进行测量，全年在每个地点进行四次测量。总共有100个住宅被选中进行研究。钍的浓度在4.6 ~ 143.5Bqm− 3之间变化，几何平均值为25.1Bqm−3。结果进行了分析，为不同类别的住宅就其建筑类型。
Thoron concentration levels have been measured in the high background radiation area located around Kudankulam nuclear power plant i.e. in the Agastheeswaram, thovalai taluks (sub-district) of the Kanyakumari district using solid-state nuclear track detectors. Measurements have been carried out on quarterly cycles making four measurements at each location throughout a year. Totally 100 dwellings have been selected for the study. Thoron concentration has been found to vary between 4.6 and 143.5Bqm−3with the geometric mean value being 25.1Bqm−3. Results have been analyzed for different categories of dwellings with respect to their construction type.
