Dear Mr. Grier:
Subject:
Calvert Cliffs Nuclear Power Plant Units Nos. 1 and 2 License Nos. DPR-53 and 69 Nonroutine Radiological Environmental Operating Report This report is submitted, in duplicate, to comply with the require-ments of Appendix B Environmental Technical Specifications Section 5.6.2.b.
The Oyster samples were collected on October 30, 1979 from the Camp Conoy sampling location and analyzed for garr.a-emitting radionuclides as required.
The results of the analyses showed the presence of Ag-110= at 253112 pCi/Kg(vet). The oyster samples collected on the same date from the Kenwood Beach' sampling location (the background location) showed Ag-110m at 5 7 pCi/Kg(vet).
Based on the observed levels of Ag-110m during this sampling period, for an average adult consuming one kilogram of oysters per year the doses to the GI Tract and Whole Body are estimated at~1.5x10-2 mrem / year and~2.2x10-5 mrem / year, respectively.
These are very small fractions of the allovable 25 crem/ year (GI Tract) and 25 mrem / year (Whole Body) doses to members of the general public, (h0 CFR Part 190 Environmental Radiation Protection Standards for Nuclear Power Operations) and are therefore considered to be of no consequence to the health and safety of the public.
Very truly yours,
/
