摘要
文章描述了一台β放射性气体活度绝对测量装置以及测量结果，装置建成之后，用￣（８５）Ｋｒ及￣３Ｈ对端效应、壁效应、吸收效应以及电子在玻璃绝缘体表面上的吸附效应等作了认真仔细的实验测、定和研究，最后测得该装置的系统不确定度为０．２４％，重复性为０．１％。本次测量的￣（８５）Ｋｒ及￣３Ｈ样品的标准误差分别为０．０６％及０．１％，合成不确定度为０．２６％。
The paper presents an absolute measurement equipment of theβ-radioactive gas and measuredresults. After the fixing work of the equipment is done,the electron adsorption effect of the glassisolator surface,the end effect, the wall effect and the absorption effect are carefully measuredand researched by ￣(85)Kr and￣3H,The equipment system error is 0.24% and repeatability is 0.1%.In the measurement,the standard errors of￣(85)Kr and￣3H samples are 0.06 % and 0.1,respectively. The resultant unceriainty is 0.26%.
