A variety of toxins are known to affect indoor air quality, thereby affecting the health of the inhabitants of that region. One such natural contaminant is radon, which is a dense, colourless, odourless and inert gas. As per BEIR-VI report (Chauhan and Chauhan in J Environ Radioact, 2015. https://doi.org/10.1016/j.jenvrad.2015.03.009 ), Radon alone contributes to more than 50% of the total natural background radiation and is the second leading element causing lung cancer after smoking. Therefore, its quantification is vital to assess any risk to human health. In order to assess health risks, a recently developed LR-115 detector based technique was employed for time-integrated passive measurements of radon, thoron and their progeny concentrations. The annual average radon concentration was found to be 35.6 Bq m −3 and thus lies well below the global average of 40 Bq m −3 . However, thoron concentration exceeded the global average value of 10 Bq m −3 .

同时测量氡、钍及其后代，用于印度 J&K 斯利那加室内吸入剂量评估

已知多种毒素会影响室内空气质量，从而影响该地区居民的健康。一种这样的天然污染物是氡，它是一种致密、无色、无味和惰性的气体。根据 BEIR-VI 报告（J Environ Radioact 中的 Chauhan 和 Chauhan，2015 年。https://doi.org/10.1016/j.jenvrad.2015.03.009），仅氡就占总天然本底辐射的 50% 以上并且是继吸烟之后导致肺癌的第二大因素。因此，其量化对于评估对人类健康的任何风险至关重要。为了评估健康风险，最近开发的基于 LR-115 探测器的技术被用于氡、钍及其后代浓度的时间积分被动测量。年平均氡浓度为 35。6 Bq m -3 ，因此远低于全球平均水平 40 Bq m -3 。然而，钍气浓度超过了全球平均值 10 Bq m -3 。
