Standardization by means of 4pibeta-gamma coincidence counting was applied to calibrate a 65Zn solution within the scope of EUROMET project no. 721. The activity result was combined with gamma-ray spectrometry measurements to investigate the photon emission probabilities. The half-life of 65Zn was measured with improved accuracy by means of 4pi ionization chamber measuring systems that were also used for secondary activity determination. In addition, we tested a new secondary standardization procedure by means of liquid scintillation counting.
在欧洲计量研究计划第721号项目范围内，采用4πβ-γ符合计数法进行标准化，以校准65Zn溶液。将活度结果与γ射线光谱测量相结合，以研究光子发射概率。通过4π电离室测量系统以更高的精度测量了65Zn的半衰期，该系统也用于二次活度测定。此外，我们通过液体闪烁计数测试了一种新的二次标准化程序。
