Chakravarti, D. and R. Eisler. 1961. Strontium-90 and gross beta activity in the fat and nonfat fractions of the liver of the coconut crab (Birgus latro) collected at Rongelap Atoll during March 1958. Pacific Sci. 15 155-159. [Pg.1739]

Gross alpha and gross beta activity can be determined by various radioactive counters, such as internal proportional, alpha scintillation, and Geiger counters. Radium in water can be measured by co-precipitating with barium sulfate followed by counting alpha particles. Radium-226 can be measured from alpha counting of radon-222. Various methods are well documented (APHA, AWWA, and WEF 1998. Standard Methods for the Examination of Water and Wastewater, 20 ed. Washington DC American Public Health Association). [Pg.786]

The gross-alpha and gross-beta activities were measured separately with a gas flow counter there were no alpha-to-beta spill-over issues. [Pg.40]

In the NVN 5636 intercomparison, six laboratories analyzed glass-fibre filters and membrane-filters for gross alpha and gross beta activity (see table 3 and table 4). The result for one laboratory was rejected as an outlier. [Pg.41]

This paper describes the analytical characteristics of four Dutch norms, dealing with the determination of gross alpha and gross beta activity in solids, filters and water [7]. A gross alpha activity is reported as an Am-equivalent and a gross beta activity as a equivalent (of course in the case where Am and are calibration nuclides). [Pg.43]
