Cage tops were fastened with 10-cm nylon cable ties and steel shackles, and were deployed by divers in the discharge of the CCNPP (38[degrees]26.
Aggregated flesh of 60-70 oysters of each species was separately massed, homogenized and analyzed in 500 mL Marinelli beakers for gamma-ray emitting radionuclides known to be released routinely by CCNPP and historically detected in caged C.
Radionuclides previously released by the CCNPP and routinely detected in caged C.
The primary goal of this study was to examine radionuclide accumulation, but we were unable to do that, because radionuclides released by the CCNPP during the study period were far below levels that would have produced detectable concentrations in the oysters.
Radioactivity released by CCNPP was not detected in either oyster species, precluding a comparison of uptake rates.
However, immersion for even a year would probably not have resulted in radionuclide accumulation given the low release levels from the CCNPP during 2004.
