Test for the determination of 90Sr in soil
Description
The standardized method is based on the chemical separation (extraction, precipitation, etc.) of 90Sr from other fission products. After long-term storage for 90Sr-90Y equilibrium the activity of the sample precipitated in the form of Y(COO)2 is measured. The Sr yield coefficient is determined by 85Sr tracer or by gravimetry. The test is applicable for the determination of 90Sr contamination originating from fallout or from other sources in soil, when the concentration of 90Sr is higher than 0.2-0.4 Bqg-1 (5-10 pCig-1). The error of the method is less than +-2% of the amount of the 90Sr present. (Sz.J.)
