A rapid method for determining 89Sr and 90Sr by Cerenkov counting.
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.
