| EFFECT OF FREEZING THE SURFACE LAYER OF SOIL ON THE RADON TRANSPORT |
A. V. Klimshin, I. A. Kozlova, E. N. Rybacov, M. Y. Lukovskoy Institute of Geophysics of the Ural Branch of the Russian Academy of Sciences, Yekaterinburg, 620016 Results of soil temperature and soil gas radon concentration monitoring are shown. A model of radon transport is developed in case of frost penetration in a soil top layer. An estimation of radon diffusion coefficient in a frozen soil layer is given. Factors of soil gas radon concentration and radon flux from soil surface are calculated, depending on depth of frost penetration and diffusion properties of soil. |
