Between 2011 and 2012, the Association of State and Territorial Solid Waste Management Officials’ (ASTSWMO’s) Radiation Focus Group developed three reference documents on naturally-occurring, radioactive materials (NORM). The first, Incidental TENORM: A Guidance for State Solid Waste Managers (April 2011), provides information to inform solid waste managers about technologicallyenhanced, naturally-occurring, radioactive materials (TENORM), including an introduction to these materials, toxicity, waste generation, and disposal. This guidance document was followed up by the release of two fact sheets: TENORM Associated with Drinking Water Treatment (May 2011) and TENORM Associated with Shale Gas Operations (July 2012).
