Measurement of radionuclide contents and 222Rn/220Rn exhalation rate in soil samples from sub-mountainous region of India

The present study involves the measurement of radionuclide contents and radon/thoron exhalation rate in soil samples collected from 30 villages Jammu district, J & K, India. Thallium-doped sodium iodide detector advanced Smart Rn Duo monitor were used for rates. radon flux was also measured by using a surface chamber technique. mass has been found to vary 15 ± 0.4 38 0.8 mBq kg?1 h?1, while thoron 90 22 4880 280 Bq m?2 h?1. mean value radium equivalent activity (99 27 kg?1) appeared be well within admissible limit 370 suggested Organization Economic Cooperation Development (2009) report. values various parameters related radiological hazards calculated, all have below safe limits given organizations. Thze outcomes pointed out that region protected danger as per health risk effects associated with these are concerned.
