描述了参加2006年度全面禁止核试验条约(CTBT)筹委会临时技术秘书处(PTS)组织进行的国际放射性核素实验室间的滤材样品比对测量的全过程。使用相对效率为76%的HPGeγ谱仪系统测量和分析了比对样品,准确识别和计算了参考样品中的11种放射性核素的活度和活度浓度,利用95Nb与95Zr活度比推算的样品零时与参考值相差仅0.57 d。
Described the whole process of the comparison of filter material samples taken at the International Radionuclide Laboratory conducted by the Provisional Technical Secretariat (PTS) of the Preparatory Committee for the Comprehensive Nuclear-Test-Ban Treaty (CTBT) 2006. Using the HPGeγ spectrometer system with a relative efficiency of 76%, the aligned samples were measured and analyzed, and the activity and activity concentrations of the 11 radionuclides in the reference samples were accurately identified and calculated. Based on the 95Nb and 95Zr activity ratios Sample zero and reference value difference of only 0.57 d.
