【摘要】 为及时掌握实验室固体氡源的密封性、纯度和适用性,利用α射气法和γ法对其主要性能进行了检测。测试中,用测氡仪连续采样测量以检测固体氡源的密封性,用α能谱仪测量采集的样品以检测其纯度,用α射气法和γ法对固体氡源饱和计数和剩余计数进行测量以计算出固体氡源的射气系数。实验结果表明:采用α法和γ法测试固体氡源的主要性能是可行的,适合于实验室氡室的建造需求。更多还原

【Abstract】 In this paper,α method and γ method were using to measure the sealing performance,purity and applicability of the solid radon source in laboratory. In the test,the sealing performance of the solid radon source was measured with a radon monitor,the purity was measured with an α spectrometer,and the emanation coefficient was obtained by calculating the saturation counts and residual counts which were measured by α method and γ method. The results show that,it is feasible to measure the performance of solid radon source by α method and γ method, and the solid radon source was suitable for the construction of radon chamber.更多还原
