摘要 中国计量科学研究院作为主导实验室,组织了全国15个实验室参加的^60Coγ射线空气比释动能量值比对。比对结果表明各参比实验室测量的比对点处空气比释动能率在0.6%以内吻合,核验比对给出的传递标准空气比释动能校准因子在0.8%以内吻合。 As the pilot laboratory, National Institute of Metrology organized the comparison for air kerma in 60Co gamma rays in China. There are 15 laboratories join the comparison. The results show that the comparison difference of air kerma rate in reference point is within 0. 6% , and the comparison difference of calibration factor for air kerma of transfer chambers is within 0. 8%.
