Silver-110m, cobalt-58, and zinc-65 concentrations in the American oyster, Crassostrea virginica (gmelin), near the Calvert Cliffs Nuclear Power Plant. Research report (Final) 1978-1986

As part of a comprehensive assessment of the radiological impact of the Calvert Cliffs Nuclear Power Plant, the Power Plant Research Program has routinely monitored radionuclide concentrations in oysters. Monitoring involved the measurement of nuclide concentrations in oysters introduced and maintained in trays in the vicinity of the plant discharge, and in a nearby natural population. Only Ag-110m, Co-58, and Zn-65 were consistently detected in oysters. Calculation of relative concentration factors show that oysters clearly bioconcentrate these radionuclides, particularly Ag-110m, but can eliminate large portions quickly if the source of the radionuclides is eliminated
