摘  要:在中国计量科学研究院(NIM)^60Coy基准实验室,将^60Coy辐射的空气比释动能及水吸收剂量基准值传递到国际原子能机构(IAEA)的FC65-G-2869电离室,给出了此电离室的^60Coy辐射的空气比释动能和水吸收剂量的校准因子,并且比较了这2个物理量的校准因子与IAEA提供的相关结果的差异。实验结果表明,NIM给出的FC65-G-2869电离室的^60Coy辐射的空气比释动能和水吸收剂量的校准因子相对IAEA提供的结果分别偏差0.5%和0.1%,比对结果达到了相关要求。为NIM参与国际计量局(BIPM)组织的正在进行中的一轮^60Coy辐射的空气比释动能及水吸收剂量的关键比对作了前期准备。In the ^60Coy primary standard laboratory at National Institute of Metrology(NIM), the primary standard values of the air keama and absorbed dose to water of ^60Coy radiation were disseminated to the FC65-G-2869 chamber from International Atomic Energy Agency(IAEA), and then the calibration factors were obtained.The calibration factors of the two physical quantities given by NIM were compared with the original calibration factors from IAEA.For the NIM calibration factors of the air kerma and absorbed dose to water of ^60Coy radiation to the IAEA FC65-G-2869 chamber, the discrepancies are 0.5% and 0.1% respectively, relative to the corresponding IAEA results.The comparison results are considered to be acceptable.This work is the preliminary preparation for NIM to participate in the ongoing Bureau International des Poids et Mesures(BIPM) key comparisons for the air kerma and absorbed dose to water of ^60Coy radiation.
