A study on natural radioactivity and potential of .sup.222Rn, .sup.220Rn exhalation from Deccan table land of Kolhapur district, Maharashtra, India

In this study, an investigation has been carried out on the potential of radon, thoron and natural radioactive content by collecting soil samples from the Deccan land of Kolhapur district, India. The mean value of radon mass exhalation rates is 12.66 ± 1.07 mBqkg.sup.-1h.sup.-1 and mean thoron surfa...

Description
Summary:In this study, an investigation has been carried out on the potential of radon, thoron and natural radioactive content by collecting soil samples from the Deccan land of Kolhapur district, India. The mean value of radon mass exhalation rates is 12.66 ± 1.07 mBqkg.sup.-1h.sup.-1 and mean thoron surface exhalation rate is 2300 ± 261 Bqm.sup.-2h.sup.-1. The mean value of Radon emanation factor is 5.18%. The mean activity concentrations of .sup.238U, .sup.232Th and .sup.40K in the soil samples are 9.33 ± 0.45 Bqkg.sup.-1, 16.60 ± 0.77 Bqkg.sup.-1 and 66.15 ± 4.33 Bqkg.sup.-1 respectively and well below the value recommended by UNSCEAR 2000.
