摘　　要：用双滤膜方法对居室和建材的氡析出率进行了可行性测定及探讨 ,数个测点实测结果表明 :与常规的活性炭方法相比 ,双滤膜方法原理可行 ,操作简单 ,结果可比 ,是一种更加灵敏、高效、快速的氡析出率测定方法 .It was studied that feasibility which Radon-222 exhalation (δ) of houses and building materials was determined with double-filter method and discussed that determining results of several observed points in this paper. It was shown that, compared with active carbon method, the principle of double-filter method was feasible, the operation was simple, the result was compared. It was a more sensitive,more efficient and faster determining method of Radon-222 exhalation.
