Abstract

In this study, we applied support tool(Impara) for environmental parameter estimation to evaluation of radon and thoron exhalation rates from soil surface. This support tool was developed for estimation of soil-to-soil solution distribution coefficient(Kd) and soil-to-plant transfer factor(TF). As a result of multiple linear regression analysis, radium content in the soil, emanation coefficient, volumetric water content and soil temperature were important parameters for estimation of radon and thoron exhalation rates from soil surface. Comparisons of measured and estimated radon/thoron exhalation rates showed relatively good agreement.
