Strontium-90 in seawater samples was analyzed aboard the USS Knorr by direct extraction of the90Y daughter. The extraction was made in two 17-gallon heavy-walled glass bottles. Yttrium carrier was added and the90Y was extracted with HDEHP in toluene, back-extracted with HCl, and purified with a second HDEHP extraction. The Y was mounted as the oxalate and counted in a methane end window system. Check analyses were performed in a shorebased laboratory equipped with low background beta counters. The results of the sea and shore analyses were consistent within the limits of error. The test demonstrates that90Sr analyses can be performed satisfactorily at sea, and that a better equipped laboratory and counting facility would improve the performance considerably.
