摘要：

A series of simulation experimentations are carried out on the overburden soil of the uranium tailings impoundment under the conditions of heat and insolation. The results show that: (1) The radon exhalation rate on the overburden soil of the uranium tailings impoundment increases rapidly at first and then slows down with the decrease of the moisture content. (2) The radon exhalation rate increases rapidly at first and then slows down with the increase of fractal dimension. The fitting formula of the influence of moisture content and fractal di...
