摘　　要：本文在讨论均匀漏气氡室中氡活度积累规律的基础上，导出了计算氡室漏气率（λｇ）及氡源有效强度（Ｒ）的方程组。采用迭代算法编程求解，计算出λｇ和Ｒ的值，并通过实验证明计算结果的正确性。使用本方法，可方便地确定氡室漏气率及氡源有效强度，同时也为修正非严格密封的补气式氡室的控制参数提供了依据。On the basis of radon accumulation in even leaking radon chamber,a simultaneous equation is derived in this paper which is used to calculate the leaking rate ( λ g) of the radon chamber and effective.radon source strength ( R ) by repeated algorithm according to the principle of least square method.And the results are proved to be true through experiments.Thus,it is possible to determine the leaking rate of the radon chamber and effective radon source strength precisely and conveniently.Meanwhilt,it provides theoretical basis for revising the controlling parameters of not tightly sealed radon chambers.
