The air-kerma standards used for the measurement of medium-energy x rays were compared at the National Institute of Standards and Technology (NIST) and at the Bureau International des Poids et Mesures (BIPM). The comparison involved a series of measurements at the BIPM and the NIST using the air-kerma standards and two NIST reference-class transfer ionization standards. Reference beam qualities in the range from 60 kV to 300 kV were used. The results show the standards to be in agreement within the combined standard uncertainty of the comparison of 0.35 %.
在美国国家标准与技术研究院（NIST）和国际计量局（BIPM）对用于中能X射线测量的空气比释动能标准进行了比较。该比较涉及在BIPM和NIST使用空气比释动能标准以及两个NIST参考级传递电离标准进行的一系列测量。使用了60 kV至300 kV范围内的参考射线质。结果表明，在比较的合成标准不确定度0.35%范围内，这些标准是一致的。
