摘要：
A novel method for direct measurement of 90Sr in liquid samples was developed by using liquid scintillation counter. Based on the shielding performance analysis and the optimum package investigation, the proposed method provides an excellent shielding for the interferences of α-emitters, low- and intermediate-energy β-emitters. A minimum detection activity of 8.0 ± 0.6 Bq·L−1 for 90Sr was obtained. Due to the effective elimination of the quenching interference and counting interference, the method presented in this work can provide the results of 90Sr analysis within 1 h after receiving the sample.
