Radiological Measurements at Superfund Sites


A. Fellman, S. McNulty


In 1980, the United States Environmental Protection Agency (EPA) promulgated the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) to address the environmental and public health threats posed by chemical and radioactive pollutants at inactive hazardous waste sites. Since its inception, 1,211 sites have been placed on the National Priorities List (NPL), making them eligible for investigation and/or remediation under the CERCLA (commonly known as Superfund) program. Of these, approximately 50 sites were placed on the NPL primarily or in part due to the presence of radioactive contaminants in environmental media. These include many sites which comprise the Formerly Utilized Sites Remedial Action Program (FUSRAP), formerly run by the United States Department of Energy (DOE) and now under the authority of the United States Army Corps of Engineers (ACE). The majority of these sites contain elevated levels of uranium and/or thorium series radionuclides in waste residues. As a result of the physical mobility of the waste residues, many sites contain numerous commercial, municipal, and/or residential properties with potentially contaminated soil, water, structural material, and indoor air. This paper describes the various types of equipment/instrumentation used to collect radiological data as a site progresses through the Superfund life cycle.
