Description

The conventional dual label DPM(DL-DPM) and full spectrum DPM(ES-DPM) counting method for determination of 90Sr was comparing under the aspect of the accuracy and detection limits, and the FS-DPM method was applied to determine the 90Sr in liquid waste samples. In liquid scintillation counting, the activity concentrations of 90Sr and 90Y were calculated from quench correlation curves related with SIS and tSIE quench indicators. Direct measurement of purified 90Sr with spectrum unfolding techniques could overcome the disadvantages of the DL-DPM method. The activities of 90Sr in the 90Sr/90Y standardized solution measured with the FS-DPM protocol were close to the true activity. The measurement of 90Sr in the liquid waste samples with the FS-DPM counting method was easier and faster than that with the DL-DPM method, since optimization of counting regions is not necessary
