Xe has been standardized by means of an internal gas proportional counting system, employing a length-compensated method. The activity concentration of Xe was measured with a relative standard uncertainty of 0.6%. The gamma-ray emission probability of Xe was then determined as 0.0196(4) by measuring a standard sample of Xe using a high-purity germanium (HPGe) spectrometer.
氙已通过采用长度补偿法的内部气体比例计数系统进行了标准化。氙的活度浓度通过相对标准不确定度为0.6%进行测量。然后，通过使用高纯锗（HPGe）光谱仪测量氙的标准样品，确定氙的γ射线发射概率为0.0196(4)。
