90 Sr on SPE disks may be counted by either liquid scintillation or proportional counting. These two methods have both been employed in literature, but detailed description about counting conditions and efficiencies were not presented. In this work, counting efficiency using liquid scintillation counting was determined. The counting efficiency of 90Sr on SPE disks was approximately 99% by scintillation counting, which implied that the effect of self-adsorption of disk was negligible.
