| Abstract: | According to the theory of flow diffusion and convection, three dimensional state equation of radon field is established for constant and variable diffusion coefficient and convection rate. The numerical solutions for different coefficient and different boundary conditions are obtained for two models of radon field which have respectively source in the side and inside of collapse column. The numerical computations have been made using difference method for difference characteristics and boundary conditions. The computation results show the state features of radon field in space. The results of the field survey and model test are coincide. |
