Environmental radionuclide concentrations in the vicinity of the Calvert Cliffs Nuclear Power Plant: 1981 - 1984. Data report
High-resolution gamma spectroscopy was used to determine radionuclide concentrations in over 700 sediment, finfish, shellfish, and aquatic-vegetation samples collected from the Chesapeake Bay in the vicinity of the Calvert Cliffs Nuclear Power Plant (CCNPP) during 1981-1984. Naturally-occurring radionuclides (K-40; thorium and uranium decay products) and weapons-test-fallout radionuclides (principally Cs-137) were detected in all samples. The down-Bay transport of radionuclide-labelled particulates was documented in sediments collected from stations located 8 km south of CCNPP. Low concentrations of Sr-90 detected in biota collected at plant-site and Farfield locations were not significantly different and are attributable to weapons-test fallout. The low quantities of radioactivity discharged by CCNPP provide small increments to radionuclide concentrations in the Bay relative to natural and weapons-test levels.
