摘要

澳大利亚辐射防护和核安全局（ARPANSA）和国际原子能机构（IAEA）的空气质量标准进行了比较，RQR， RQA和RQT辐射质量（按照IEC 61267或IAEA TRS 457的规定）使用两个电离室作为转移标准。RQR光束的IAEA和ARPANSA校准系数之比为0.993 ~ 0.997，RQA光束的IAEA和ARPANSA校准系数之比为0.990 ~ 0.999，RQT光束的校准系数之比为0.993 ~ 0.994。IAEA和ARPANSA的相对扩展不确定度分别为1.2和1.4%，所有光束的比较结果在0.74%的综合标准不确定度附近或更好。

Comparison of the air kerma standards of ARPANSA, Australia, and the IAEA in RQR, RQA, and RQT diagnostic X-ray beams.

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.
