摘要

采用SMART RnDuo活性氡/钍监测仪对阿利格尔哈杜甘杰热电厂(HTPP)周边地区土壤样品的氡质量和氡表面呼出率进行了测量。氡质量呼出率范围为27±1 ~ 100±3 mBq kg−1 h−1，平均值为63±17 mBq kg−1 h−1。肺表面呼出速率变化范围为1.0±0.2 ~ 10±1 kBq m−2h-1，平均值为5.7±2.2 kBq m−2h-1。氡质量和氡表面呼出率的平均值高于世界平均值

Radon and Thoron Exhalation Rate Measurements in Soil Samples Collected from the Vicinity of a Thermal Power Plant

Radon mass and thoron surface exhalation rate of soil samples collected from the surrounding area of Harduaganj thermal power plant (HTPP), Aligarh is measured using an active radon/thoron monitor (SMART RnDuo). The radon mass exhalation rate values range from 27±1 to 100±3 mBq kg−1 h−1 with a mean value of 63±17 mBq kg−1 h−1. The thoron surface exhalation rate values vary from 1.0 ± 0.2 to 10±1 kBq m−2h-1 with a mean value of 5.7 ± 2.2 kBq m−2h-1. The mean values of radon mass and thoron surface exhalation rate are found to be higher than the worldwide mean values
