چکیده انگلیسی
A simple, rapid and cost-efficient method for determination of activity concentration of 90Sr in biological samples with an extraction chromatographic column (crown ether on teflon powder) and following counted by liquid scintillation counting was developed in this paper. The column retained most of 90Sr while almost all of matrix ions were removed during rinsing steps with 8M nitric acid and finally 90Sr was eluted with deionized water, the chemical recovery of strontium is greater than 60%, almost all of matrix ions were removed by the procedure we reported. Finally the uncertainty was evaluated and minimum detectable activity of this method is 1.28Bq/kg.
