Estimation of surface exhalation rate of thoron (²²⁰Rn) in soil samples of Aravalli Mountain range region of district Mahendergarh, Haryana, India using alpha detector Smart Rnduo

Human beings are continuously exposed to natural radiation such as terrestrial radiation sources. These radiations are produced by the natural breakdown of rocks, soil, vegetation, other natural radioactive decay, etc. Alpha rays released from natural radionuclide of Radium (²²⁶Rn) decay series found in soil, water, and rocks are terrestrial radiation. The radionuclide Radon (²²²Rn) and Thoron (²²⁰Rn) are generated from Radium (²²⁶Rn) in the series of Uranium-238. The present research discusses the evaluation of radionuclide thoron surface exhalation rate in soil samples of the District Mahendergarh of Haryana, India. In context to its geology, this place is near the Khetri copper mines and in the range of 'Aravalli Hills', unique rocks and illegal mining in this area are the primary conditions of motivation for researching this particular area, also first time study has been carried out, no data has been recorded earlier
