摘　　要：介绍了一套实验装置,可通过该装置了解吸附了氡气的活性炭的放射性计数与活性炭所在环境的氡浓度的关系。活性炭中氡或其衰变子体放出的γ射线的总计数与氡浓度成线性关系;γ射线的总计数经过校正后,可以换算成活性炭所在环境的氡浓度。With a set of apparatuses designed by the authors, we can detect the relationship between the radioactive counting of radonadsorbing active carbon and the radon concentration of the environment in which the active carbon exists. The total counts of radon in active carbon orγrays released from its decay daughter are in linear relationship with the radon concentration. After correction, the total counts of γrays can be converted into radon concentration in the environment.

关 键 词：活性炭 氡气测量 Γ射线 吸附饱和性实验
