“…After the sample was loaded, a tube rinse of ~3 ml 3M HNO 3 was transferred to the stacked column and a rinse of 5 ml 3M HNO 3 was added directly to the stacked column. The TRU Resin and Sr-Resin cartridges were removed and the TEVA cartridges 7 were kept on the vacuum box. The TEVA cartridge was rinsed with 15 ml 3M nitric acid to remove sample matrix components.…”

Significant method improvements were applied to reduce analytical times. As a result, much faster analysis times were achieved, less than 3 hours for determination of 90 Sr and 3-4 hours for actinides. This represents a 25%-33% improvement in analysis times from NRIP 2007 and a ~100% improvement compared to NRIP 2006 report times. Column flow rates were increased by a factor of two, with no significant adverse impact on the method performance. Larger sample aliquots, shorter count times, faster cerium fluoride microprecipitation and streamlined calcium phosphate precipitation were also employed.Based on initial feedback from NIST, the SRS Environmental Bioassay Lab had the most rapid analysis times for actinides and 90 Sr analyses for NRIP 2008 emergency urine samples. High levels of potential matrix interferences may be present in emergency samples and rugged methods are essential. Extremely high levels of 210 Po were found to have an adverse effect on the uranium results for the NRIP-08 urine samples, while uranium results for NRIP-08 water samples were not affected. This problem, which was not observed for NRIP-06 or NRIP -07 urine samples, was resolved by using an enhanced 3 210 Po removal step, which will be described.

“…The activity of 90 Sr was determined using the Cerenkov counting method [26]. 2 mL of the sample was precipitated as carbonate, dissolved in 8 M nitric acid, and extracted with Sr resin (Eichrom); after 7 days of ingrowth of 90 Y, the daughter nuclides, the activities of 90 Sr were measured [27,28].…”

“…Therefore, it has been successfully applied in many laboratories worldwide and it has found wide application in physical, chemical and biological research. Most frequent application of Cherenkov counting is the analysis of 89 Sr and 90 Sr via 90 Y [2,3] as their determination is a part of routine environmental radiological monitoring programs. Cherenkov counting enables undemanding distinction between 90 Sr and 90 Y.…”

The Cherenkov counting efficiencies measured by three commercially available liquid scintillation counters, Triathler, Tri-Carb 3180, Hidex 300 SL were compared. The influences of energy of pure beta emitters, volume, and solvent as well as instrument type on Cherenkov counting efficiency were studied. The best Cherenkov counting efficiencies are on the Hidex 300 SL and when methanol is used as a solvent. It could be concluded that the sensitivities of low-level versions of Tri-Carb and Hidex 300 SL are comparable. Based on the overall results obtained it has been concluded that the TDCR Cherenkov counting is well suited for routine quantitative determination of low activities of high energetic beta emitters.
