In this paper, we intend to evaluate the rate of radon and thoron exhalation from soil with reference to the underlying bedrock and gamma dose rate in the environment of elevated granitic hill-Nandi hills of Karnataka. The measurement of exhalation rates for all the soil samples collected from study area was carried out using a continuous radon-thoron monitor (Smart RnDuo monitor). The surface exhalation rate of thoron from soil samples were found to vary from 4160 ± 326 to 21 822 ± 634 mBq m-2 s-1. The mass exhalation rate of radon from soil samples were found to vary from 76 ± 6 to 269 ± 19 mBq kg-1 h-1. Concentrations of radon activity measurements were carried out for all the groundwater samples from study area. A detailed analysis along with physicochemical parameters of water has been made and discussed in this research paper.
本文旨在评估基岩下氡和钍的土壤排放率以及卡纳塔克邦高花岗岩丘陵-楠迪丘陵地区的环境中的伽马剂量率。使用连续氡-钍监测仪(Smart RnDuo 监测仪)对从研究区域采集的所有土壤样本的排放率进行了测量。发现土壤样本中钍的表面排放率从 4160 ± 326 到 21 822 ± 634 mBq m-2 s-1 不等。从土壤样本中测量到的氡的质量排放率从 76 ± 6 到 269 ± 19 mBq kg-1 h-1 不等。对研究区域的所有地下水样本都进行了氡活度浓度测量。在本研究论文中对水的详细理化参数进行了分析和讨论。
