Abstract
In this paper a complete and self-consistent method for Sr-90 determin ation in environmental samples is presented. It is based on the Cheren kov counting of Y-90 with a conventional liquid scintillation counter. The effects of color quenching on the counting efficiency and backgro und are carefully studied. A working curve is presented which allows t o quantify the correction in the counting efficiency depending on the color quenching strength. (C) 1998 Elsevier Science B.V. All rights re served.
