摘要：

A new method for the measurement of 90Sr in environmental samples by cation-exchange and liquid scintillation counting is described. Strontium carbonate is purified by precipitation and ion-exchange, weighed for the determination of chemical yield, dissolved in hydrochloric acid and mixed with the liquid scintillator, Aquasol-2. Two channels of a low-background liquid scintillation counter are used to determine 90Sr, 90Y and 89Sr, free from the effects of environmental tritium. The values of 90Sr obtained by this method are in good agreement with those from ordinary 90Y milking and the gas proportional counting method. The concentration of 90Sr in the air at Tokai-mura in Japan has been measured by the new method. © 1990.
