[en] The aerial survey of the Turkey Point Plant covered a 140-square-kilometer (55-square-mile) area that included the reactor facility and an area of cooling channels located immediately south of the reactor facilities. The reactor and cooling channels were on the eastern edge of the survey area. The survey was conducted during the period 18 to 26 March 1983. Inferred exposure rates, except over the site, were due primarily to naturally occurring gamma ray emitting radionuclides and cosmic ray activity (estimated at 3.1 μR/h). The exposure rates varied from 3 to 6 μR/h in background areas; the most frequently occurring range was 3 to 4 μR/h. The maximum inferred exposure rate over the site was 140 μR/h. Spectral analysis revealed cobalt-60 as the primary contributor to the elevated exposure rate over the reactor facilities. Results of ground-based measurements taken at four locations within the survey area were consistent with the aerial data. Data collected during this survey were also consistent with results from a previous survey conducted in April 1972. 3 references, 8 figures, 3 tables
