Abstract

Environmental radioactivity due to radon, thoron and their progenies in the ambient air in the multi-storeyed malls situated in Delhi National Capital Region (NCR) including district Faridabad, Haryana (India) was evaluated using LR-115 (type-II) SSNTDs. The average value of activity in different seasons due to radon and thoron varied from 18.45 ± 1.95 Bqm−3 to 45.37 ± 4.69 Bqm−3 and 10.64 ± 0.94 Bqm−3 to 22.91 ± 1.88 Bqm−3 respectively. The collective annual exposure and annual effective dose due to radon and thoron varied from 45.37 × 10−3 WLM to 295.67 × 10−3 WLM with an average value of (159.88 ± 3.66) × 10−3 WLM, and 0.17 mSv to 1.13 mSv with an average value of 0.61 ± 0.01 mSv respectively during the four seasons of the year. Owing to poor ventilation in basement of malls, the annual effective dose is high compared with upper floors of the malls where proper ventilation is provided.
用塑料轨迹探测器测定德里NCR(印度)多层商场氡-钍及其子体剂量
使用LR-115(II型)SSNTD评估了位于德里国家首都地区(NCR)(包括哈里亚纳邦法里达巴德区)的多层购物中心环境空气中氡、钍及其后代引起的环境放射性。氡和钍在不同季节的平均活度值分别为18.45±1.95 Bqm−3至45.37±4.69 Bqm–3和10.64±0.94 Bqm-3至22.91±1.88 Bqm-3。氡和钍的集体年暴露量和年有效剂量在一年四季分别为45.37×10−3 WLM至295.67×10−3WLM,平均值为(159.88±3.66)×10−3HLM,0.17 mSv至1.13 mSv,平均值0.61±0.01 mSv。由于商场地下室通风不良,与通风良好的商场上层相比,年有效剂量较高。
