Radioactive emissions from coal production and utilization. Second annual progress report, October 1, 1979-September 30, 1980

;
During FY 80 we analyzed a variety of coals and coal-related solids for radionuclide content, we leached a number of solids and analyzed the leachates, and we measured the emanation from a variety of coals and related solids. The purpose of these investigations is to establish a suitable data base from which to evaluate the magnitude of the radiologic hazards from coal use, and if warranted, to devise control technology to mitigate the hazards identified. Based on the limited number of samples received, our studies indicate that the coals, related solids, their leachates, and emanations present very little radioactivity of environmental concern. Most of the solid samples and their /sup 222/Rn emanations pose a hazad comparable to that of ordinary soils. Some of the fly ashes may be exceptions. Two samples showed elevated /sup 226/Ra, /sup 210/Pb, and /sup 210/Po levels in the small particle fractions. None of the leachates prepared exceeds the maximum permissible concentration (MPC) in Code of Federal Regulation (CFR)-10 for any of the /sup 238/U of /sup 232/Th series radionuclides; most are a few percent or less of the MPC.
