Rapid method for determination of the activity concentrations of (89)Sr and (90)Sr.
This paper describes a rapid method for determining the activity concentrations of (89)Sr and (90)Sr in air and water using LSC. After sample preparation strontium is separated by extraction chromatography. The chemical yield is determined by X-ray fluorescence. The spectra of the Cerenkov radiation and beta radiation are taken with a LSC. From both spectra the activities of strontium are calculated by means of a spectrum deconvolution method. The results can be obtained within 4.5 hours for particulate filters and 2 hours for water.
