SRLOG, the simultaneous standardization of 90Sr+90Y+89Sr mixtures

Abstract
A program is presented that permits the simultaneous standardization of the three-nuclide mixture ^(90)Sr+^(90)Y +^(89)Sr in liquid-scintillation spectrometers with logarithmic pulse-height spectra outputs. The application of a new spectrum interpolation method permits one to obtain the spectral shape of each component for the quench value of the mixture while the standardization of the separated components is achieved by the CIEMAT/NIST tracing method.

Title of program: SRLOG
Catalogue Id: ACTY_v1_0

Nature of problem
89Sr and 90Sr are fission products, which receive considerable attention in security programmes of nuclear power stations. The radiostrontiums can be easily isolated from other radioactive isotopes by using cation exchange columns. However, 90Sr decays to its daughter 90Y, which transforms the mixture in a three-nuclide problem: 90Sr+90Y+89Sr.

本文提出了一种程序，允许在具有对数脉冲高度谱输出的液体闪烁谱仪中同时标准化由三种同位素混合物构成的反冲核 ^{90}Sr+^{90}Y 与 ^{89}Sr。通过应用一种新的谱线插值方法，得以在混合物的淬灭值下获得各成分的谱形。而分离成分的标准化则通过 CIEMAT/NIST 跟踪法实现。

程序名称：SRLOG

问题性质：^{89}Sr 和 ^{90}Sr 是裂变产物，在核电站的安全计划中受到广泛关注。通过阳离子交换柱，可以轻易地将放射性锶同位素与其他放射性同位素分离。然而，^{90}Sr 会衰变为其子同位素 ^{90}Y，将混合问题转化为包含 90Sr、90Y 和 89Sr 的三种同位素问题。
