Abstract

Indoor radon and thoron concentrations have been measured using solid state nuclear track detector (LR-115 type-ІІ) based twin cup dosimeter with single and double entry deployed side by side. The measurements have been carried out in 50 dwellings of 8 different villages/towns situated in Saiha and Lawngtlai districts, Mizoram. Dwellings were selected primarily from the gamma level measured using Micro-R survey meter and the construction type of the building. The average concentrations of radon and thoron were found to be 75.76 Bq/m3 and 96.50 Bq/m3 for single entry dosimeter and 63.47 Bq/m3 and 19.79 Bq/m3 for double entry dosimeter. The single entry dosimeter was found to give more reliable observations than that of double entry in terms of trends of seasonal data and also on the theory behind the manufacturing qualities.

单入口和双入口双杯剂量计在印度米佐拉姆邦测量室内氡和钍浓度的比较

室内氡和钍浓度已使用固态核径迹探测器(LR-115型-ІІ)双杯剂量计进行测量，单入口和双入口并排部署。这些测量是在米佐拉姆邦Saiha和lawinglai地区8个不同村庄/城镇的50所住宅中进行的。住宅主要是从使用Micro-R测量仪测量的伽马水平和建筑物的建筑类型中选择的。单入口剂量计测得氡和钍的平均浓度分别为75.76 Bq/m3和96.50 Bq/m3，双入口剂量计测得氡和钍的平均浓度分别为63.47 Bq/m3和19.79 Bq/m3。人们发现，就季节数据的趋势和生产质量背后的理论而言，单入口剂量计提供的观测结果比双入口剂量计更可靠。
