Title: Environmental radionuclide concentrations in the vicinity of the calvert cliffs nuclear power plant: 1985-1986. Final report

Abstract

High-resolution gamma spectroscopy was used to determine radionuclide concentrations in sediment, finfish, shellfish, and aquatic vegetation collected from the Chesapeake Bay in the vicinity of the Calvert Cliffs Nuclear Power Plant (CCNPP) during 1985-1986. Low concentrations of radionuclides attributable to CCNPP (Ag-110m, Co-58, Co-60, and Zn-65) were detected in all biota (except edible finfish) and in sediments. Silver-110m was the principal CCNPP-related radionuclide detected in biota (particularly oysters); Co-58 and Co-60 were the principal CCNPP-related radionuclides detected in sediments. CCNPP-related radionuclide concentrations detected in Bay biota and sediments were within ranges observed in previous years and represent small increments to radionuclide concentrations in the Bay relative to natural and weapons test levels.

  • The Maryland Power Plant Research Program monitors concentrations of natural, weapons, and power plant produced radionuclides in environmental samples collected from the Chesapeake Bay in the vicinity of the Calvert Cliffs Nuclear Power Plant (CCNPP) and from the Susquehanna River-Chesapeake Bay system in the vicinity of Peach Bottom Atomic Power Station (PBAPS). The purpose of this monitoring is to determine the fate, transport, and potential effects of power plant-produced radionuclides.

  • 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 ofmore » radioactivity discharged by CCNPP provide small increments to radionuclide concentrations in the Bay relative to natural and weapons-test levels.« less
  • High resolution Ge(Li) spectroscopy was employed in the determination of gamma ray emitting radionuclide concentrations in a variety of environmental samples collected in the vicinity of the Baltimore Gas and Electric Company's nuclear power plant located on the Chesapeake Bay at Calvert Cliffs, Maryland. Nearfield gamma radioactivity levels in samples associated with the estuary, including sediments, finfish, shellfish and some macrophytes, were measured. Farfield surface soil, lichen and grass clipping samples were also analyzed to determine levels of gamma emitting radionuclides.
