A new combination of simple preparation techniques for determining (89)Sr and (90)Sr in water and milk samples using alginate has been developed and tested. By means of Cerenkov counting without a long ingrowth period for (90)Y, results can be obtained within 4 days. The detection limit is about 1 Bq/l for a sample volume of 0.2l. Milk samples can be prepared without ashing. A Liquid Scintillation Counter TRI-Carb 3170TR/SL in low-level mode has been used for counting.
已经开发并测试了一种使用藻酸盐测定水和牛奶样品中（89）锶和（90）锶的简单制备技术的新组合。通过切伦科夫计数，无需（90）钇的长时间生长周期，4天内即可获得结果。对于0.2升的样品体积，检测限约为1 Bq/升。牛奶样品无需灰化即可制备。使用低本底模式的液体闪烁计数器TRI-Carb 3170TR/SL进行计数。
