摘要：
A method for the determination of Sr-89/-90 in different types of environmental samples (German IMIS program) was to be adopted to the 2(nd) Saxon state laboratory for environmental radioactivity. Resulting from literature studies a combination of variable extraction steps for Y and Sr was chosen to be able for determining Sr-90 or Sr-89/-90 in a common as well as a rapid way. Measurements with a liquid-scintillation counter (LSC) and a low-background proportional counter (LBC) were performed after the same chemical separation steps in each case to find out the detector which is the best suitable one for our requirements. Different steps of the analytical procedure are discussed in detail and its characteristic parameters are given.
