An absolute standardisation of ⁸⁹Zr was performed alongside determination of gamma emission intensities and half-life. The collected data were evaluated alongside complementary works from previous publications and new recommended nuclear data values are presented including a new evaluated T_1/2 = 78.361(25) h and new absolute intensities for gamma transitions resulting from its decay to ⁸⁹Y. Dial settings for commercially available radionuclide calibrators are also presented and show a relative difference of approximately 3% compared to previously published values.

绝对标准化和测定⁸⁹ Zr的半衰期和伽马发射强度

在确定γ发射强度和半衰期的同时，进行了⁸⁹ Zr的绝对标准化。对收集到的数据进行了评估，并结合了先前出版物的补充著作，并提出了新的推荐核数据值，包括新评估的T _1/2  = 78.361（25）h以及因其衰减至⁸⁹ Y而引起的伽马跃迁的新绝对强度。还提供了用于商用放射性核素校准品的样品，与先前公布的值相比，其相对差异约为3％。
