The currently published (223)Ra gamma-ray emission probabilities display a wide variation in the values depending on the source of the data. The National Institute of Standards and Technology performed activity measurements on a (223)Ra solution that was used to prepare several sources that were used to determine the photon emission probabilities for the main gamma-rays of (223)Ra in equilibrium with its progeny. Several high purity germanium (HPGe) detectors were used to perform the gamma-ray spectrometry measurements.
目前已发表的(223)镭伽马射线发射概率,其数值因数据来源不同而有很大差异。美国国家标准与技术研究院对一种(223)镭溶液进行了活度测量,该溶液被用于制备多个源,这些源用于确定与子体处于平衡状态的(223)镭主要伽马射线的光子发射概率。使用了多个高纯锗(HPGe)探测器进行伽马射线能谱测量。
