以双区扩散理论为基础,导出铀尾矿单覆盖层体系和多覆盖层体系覆盖厚度的近似计算式。并通过覆盖前后氡析出率的测定,得到被覆盖材料和覆盖材料与氡扩散析出的有关参数,进而导出覆盖厚度的计算式。
Based on the theory of double-zone diffusion, an approximate formula for calculating the thickness of the covering system of uranium tailing system and the covering system is deduced. Through the determination of the radon precipitation rate before and after the coating, the relevant parameters of the covering material and the covering material with the radon diffusion were obtained, and then the formula of the covering thickness was deduced.
