| Abstract: | An aerial radiological survey was conducted during the period April 15--27, 1991, over an area surrounding the former location of a Chemetron Corporation factory and an associated disposal site. The area surveyed is situated in Newburgh Heights, Ohio, 3 kilometers south of Cleveland, Ohio. The purpose of the survey was to measure and document the gamma ray environment of the former factory and dump site and surrounding area. Contour maps showing gamma radiation exposure rates at 1 meter above ground level were constructed from the aerial data and overlaid on an aerial photograph of the area. The exposure rates measured within the survey region were generally uniform and typical of natural background: 3--7 microroentgens per hour (μR/h), excluding an estimated cosmic ray contribution of 3.6 μR/h. Enhanced exposure rates not attributable to natural background were measured over three areas within the survey region. Two areas, both within the boundary of a sewage processing plant, showed evidence of cobalt-60 (⁶°CO). A third area, measured over a chemical factory, showed evidence of thorium-232 (²³²Th). Radionuclide assays of soil samples and pressurized ionization chamber measurements were obtained at seven locations within the survey boundaries. These measurements are in agreement with the aerial data. |
