The 4pibeta-4pigamma coincidence counting and 4pi(beta+gamma) integral counting techniques were applied for the standardization of 152Eu and 154Eu. In these techniques, the beta-detector is composed of two thin plastic scintillators sandwiching the source coupled with a slender photomultiplier tube. This beta-detector was inserted into a large well-type NaI(Tl) scintillation detector for gamma-ray detection, making a 4pibeta-4pigamma detector configuration. The results obtained by the above two techniques were in good agreement and consistent with the results of international comparisons.
4pibeta - 4pigamma符合计数和4pi（β + γ）积分计数技术被应用于152Eu和154Eu的标准化。在这些技术中，β探测器由夹着源的两个薄塑料闪烁体组成，并与一个细长的光电倍增管相连。这个β探测器被插入一个用于γ射线探测的大尺寸井型碘化钠（铊）闪烁探测器中，形成一个4pibeta - 4pigamma探测器配置。通过上述两种技术获得的结果吻合良好，并且与国际比对结果一致。
