AbstractAbstract
[en] The concentrations of 226Ra and 222Rn (214Pb) were measured as a function of depth within a uranium mill tailings pile by in-situ gamma-ray spectrometry. Radon diffusion and exhalation rates were determined from the concentration gradients by employing an integral solution of the diffusion equation that accommodates a nonuniform depth distribution of the parent radium. Radon diffusion coefficients of 0.0002 and 0.0017 cm2/sec, and exhalation rates of 60 and 275 atoms/cm2/sec were determined for two locations with differing soil moisture content
