Özet

In this study, two different separation methods for the determination of 90Sr activity concentration in soil were described, and results were compared. The first method is based on the separation of the daughter yttrium-90 (90Y) at sequilar equilibrium by using solvent extraction and measurement of 90Y by Cherenkov counting. The second method is based on the isolation of 90Sr from other radionuclides using strontium resin and measurement with liquid scintillation spectrometry (LSS). The analytical quality of the methods was checked by analyzing IAEA Soil-375 reference material. The radiochemica! recovery of the recommended methods ranged from 75 to 83% and 80 to 92% for the Cherenkov counting and liquid scintillation spectrometric methods (LSS), respectively. Counting efficiency is 68% for Cherenkov counting and 98% for LSS methods.
