Abstract A tentative reference method for the measurement of strontium-89 and -90 in environmental waters is described. Samples of environmental water sources are collected, preserved with acid-strontium carrier, and analyzed for strontium-89 and/or strontium-90. Strontium-89 and -90 are separated from the sample water by precipitating with stable strontium carrier as carbonate. The strontium carbonate is dissolved, yttrium-90 separated, the strontium reprecipitated as carbonate, filtered, and counted for the combined strontium-89 and -90 activity. The yttrium-90 is allowed to grow in from the strontium-90 activity; the strontium carbonate is redissolved; the yttrium-90 is separated, precipitated, and counted for the strontium-90 determination. The strontium-89 activity is then determined by difference of the total strontium-89 and -90 and the separate strontium-90 activities. Recoveries are determined from the added and found (recovered) strontium carrier. Counting efficiencies are determined with prepared standard reference samples. Results are reported in pCi/liter.
