This report presents the results of a radiological survey of the burial site adjacent to the Combustion Engineering (C-E) plant in Hematite, Missouri, performed by Radiation Management Corporation (RMC) in the spring and summer of 1982. Measurements were made to determine external radiation levels, surface and subsurface radionuclide concentrations and radioactivity in air and water. Results show uranium concentrations in burial pits as high as 38 and 21 pCi/g for /sup 238/U and /sup 235/U respectively. Results also show uranium concentrations in surface soils as high as 4.7 and 1.1 pCi/g for /sup 238/U and /sup 235/U respectively. Based on an estimated /sup 234/U//sup 238/U activity ratio of about 10 to 1, the highest /sup 234/U activity in the burial pits is estimated to be 400 pCi/g, and in surface soils 47 pCi/g. Radium and thorium concentrations did not exceed background levels. Radioactivity in water which exceeded EPA drinking water standards was found in two onsite monitoring wells.
