Abstract
We study the variation of radon mass exhalation rate (Jm) and thoron surface exhalation rate (Js) with soil’s porosity and moisture content using a scintillation based monitor-Smart RnDuo. Assessment were carried out in around 40 soil samples collected from four villages of East Khasi Hills district, Meghalaya, India. Results revealed that, both Jm and Js shows no convincing trend of variation with porosity, while with respect to moisture content, a sporadic increase is observed in the values of Jm and Js up to certain level, beyond which a decreasing trend is observed; accountable reasons are discussed in the manuscript.
