This paper describes radon mass exhalation rate ( $${J}_{m })$$ J m ) and thoron surface exhalation rate ( $${J}_{s}$$ J s ) of 46 soil samples of district Faridabad, Southern Haryana, India. Scintillation detector based SMART RnDuo (AQTEK System, India) coupled with exhalation chamber was used. Outdoor gamma exposure rate was measured by GM counter based survey meter. $${J}_{m }$$ J m of one sample and $${J}_{s}$$ J s of 95% samples were found higher than world average values of 57 mBq kg −1 h −1 and 3600 Bq m −2 h −1 for $${J}_{m}$$ J m and $${J}_{s}$$ J s respectively reported by UNSCEAR 2000. No significant correlation was observed between radon/thoron exhalation rates with outdoor gamma exposure rate.

从印度南哈里亚纳邦法里达巴德地区收集的土壤样品氡/钍呼出率的量化

本文描述了法里达巴德地区 46 个土壤样品的氡质量呼出率 ( $${J}_{m })$$J m ) 和钍表面呼出率 ( $${J}_{s}$$J s ) ，印度哈里亚纳邦南部。使用了基于 SMART RnDuo（AQTEK 系统，印度）的闪烁探测器和呼气室。室外伽马暴露率由基于 GM 计数器的测量仪测量。发现一个样品的 $${J}_{m }$$ J m 和 95% 样品的 $${J}_{s}$$ J s 高于世界平均值 57 mBq kg −1 h −1和 3600 Bq m -2 h -1 对于 $${J}_{m}$$ J m 和 $${J}_{s}$$ J s 分别由 UNSCEAR 2000 报告。没有观察到氡之间的显着相关性/钍气呼出率与室外伽马暴露率。
