Determination of radon emanation coefficients of soil samples with an active and a passive method
Radon (<222>Rn) is a carcinogenic gas produced by the radioactive decay of radium (<226>Ra). Radon emissions from soil are the main sources of indoor radon problems. The goal of this study was to determine the influence of bedrock type on the coefficient of soil radon emanation. Six soils that had developed on different bedrocks were selected and sampled for this purpose. Two newly developed methods, an active and a passive detecting method, were used under laboratory conditions to measure the radon emissions from these samples. The results suggest that soil radon emanation coefficients indeed depend on bedrock and also on soil porosity. The measurements with the methods did not differ statistically.
