Abstract

A comparison of air kerma standards between the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) and the International Atomic Energy Agency (IAEA) was carried out for the RQR, RQA and RQT radiation qualities (as prescribed by IEC 61267 or IAEA TRS 457) using two ionisation chambers as transfer standards. The ratios between the IAEA and ARPANSA calibration coefficients ranged between 0.993 and 0.997 for RQR beams, 0.990 and 0.999 for RQA beams, and 0.993 to 0.994 for RQT beams. The relative expanded uncertainty for IAEA and ARPANSA was 1.2 and 1.4% respectively, and the comparison results agree at around the level of, or better than, the combined standard uncertainty of 0.74% for all the beams.

摘要

使用两个电离室作为传递标准，针对RQR、RQA和RQT辐射质（如IEC 61267或国际原子能机构（IAEA）TRS 457所规定），对澳大利亚辐射防护与核安全局（ARPANSA）和国际原子能机构（IAEA）的空气比释动能标准进行了比较。对于RQR射线束，IAEA与ARPANSA校准系数之比在0.993至0.997之间；对于RQA射线束，该比值在0.990至0.999之间；对于RQT射线束，该比值在0.993至0.994之间。IAEA和ARPANSA的相对扩展不确定度分别为1.2%和1.4%，并且所有射线束的比较结果在约0.74%的合成标准不确定度水平或更好水平上相符。
