Definitions

In addition to the definitions found in Section 39-4403, Idaho Code, terms in this chapter have the following definitions. (7-1-25) 01. Accelerator-Produced Radioactive Material. Any material made radioactive by a particle accelerator. (3-31-22) 02. Byproduct Material. (7-1-25) a. Any radioactive material (except special nuclear material) yielded in, or made radioactive by, exposure to the radiation incident to the process of producing or utilizing special nuclear material. (7-1-25) b. The tailings or waste produced by the extraction or concentration of uranium or thorium from ore processed primarily for its source material content, including discrete surface wastes resulting from uranium solution extraction processes. Underground ore bodies depleted by these solution extraction operations do not constitute “byproduct material” within this definition. (7-1-25) c. Any discrete source of radium-226 that is produced, extracted, or converted after extraction, before, on, or after August 8, 2005, for use for a commercial, medical, or research activity; or any material that: (3-31-22) i. Has been made radioactive by use of a particle accelerator; and (3-31-22) ii. Is produced, extracted, or converted after extraction, before, on, or after August 8, 2005, for use for a commercial, medical, or research activity; and (3-31-22) d. Any discrete source of naturally occurring radioactive material, other than source material, that: (3-31-22) i. The U.S. Nuclear Regulatory Commission, in consultation with the Administrator of the Environmental Protection Agency, the Secretary of Energy, the Secretary of Homeland Security, and the head of any other appropriate federal agency, determines would pose a threat similar to the threat posed by a discrete source of IDAHO ADMINISTRATIVE CODE IDAPA 58.01.10 – Rules Regulating the Department of Environmental Quality Disposal of Radioactive Materials Section 010 Page 4 radium- 226 to the public health and safety or the common defense and security; and (3-31-22) ii. Before, on, or after August 8, 2005, is extracted for use in a commercial, medical, or research activity. (3-31-22) 03. Exempt Quantities and Concentrations of Byproduct Materials. Radioactive materials defined as exempt byproduct materials by the U.S. Nuclear Regulatory Commission (10 CFR 30.14 through 30.15, 10 CFR 30.18 through 30.21, 10 CFR 32.11 and 10 CFR 32.18). (3-31-22) 04. Licensee. When used in the context of 10 CFR and these rules, the definition is Operator or Owner. (7-1-25) 05. Naturally Occurring Radioactive Material (NORM). Materials which contain any of the primordial radionuclides or radioactive elements as they occur in nature, such as radium, uranium, thorium, potassium, and their radioactive decay products. (7-1-25) 06. Operator. Any person(s) currently responsible, or responsible at the time of disposal, for the overall operation of a hazardous waste treatment, storage or disposal facility or part of a hazardous waste treatment, storage or disposal site. (3-31-22) 07. Owner. Any person(s) who currently owns, or owned at the time of disposal, a hazardous waste treatment, storage or disposal facility or part of a hazardous waste treatment, storage or disposal site. (3-31-22) 08. Radioactive Material. Radioactive Material includes: (3-31-22) a. Technologically Enhanced Naturally Occurring Radioactive Material; (3-31-22) b. Byproduct material authorized for disposal pursuant to 10 CFR 20.2008(b); (3-31-22) c. Exempt Quantities and Concentrations of Byproduct Materials; (3-31-22) d. Unimportant Quantities of Source Material, not including the natural uranium and thorium concentrations of rocks or soils; and (7-1-25) e. Any other byproduct, source material, or special nuclear material or devices or equipment utilizing such material, which has been exempted or released from radiological control or regulation under the Atomic Energy Act of 1954, as amended, to be disposed of in a commercial hazardous waste facility as regulated pursuant to the rules, permit requirements, and acceptance criteria provided for by Chapter 44, Title 39, Idaho Code. (3-31-22) 09. Reasonably Maximally Exposed Individual. That individual or group of individuals who by reason of location has been determined, through the use of environmental transport modeling and dose calculation, to receive the highest total effective dose equivalent from radiation emitted from the site and/or radioactive material transported off-site. (3-31-22) 10. Source Material. (7-1-25) a. Uranium or thorium, or any combination thereof, in any physical or chemical form; or (3-31-22) b. Ores which contain by weight one-twentieth of one percent (0.05%) or more of: (3-31-22) i. Uranium; (3-31-22) ii. Thorium; or (3-31-22) iii. Any combination thereof. (3-31-22) c. Source material does not include special nuclear material. (3-31-22) IDAHO ADMINISTRATIVE CODE IDAPA 58.01.10 – Rules Regulating the Department of Environmental Quality Disposal of Radioactive Materials Section 019 Page 5 11. Special Nuclear Material. (7-1-25) a. Plutonium, uranium 233, uranium enriched in the isotope 233 or in the isotope 235, and any other material that the U.S. Nuclear Regulatory Commission determines to be special nuclear material. (7-1-25) b. Any material artificially enriched by any of the material listed in Subsection 010.12.a. (3-31-22) 12. Technologically Enhanced Naturally Occurring Radioactive Material (TENORM). Naturally occurring radioactive material whose radionuclide concentrations are increased by or as a result of past or present human practices. (7-1-25) 13. Total Effective Dose Equivalent (TEDE). The sum of the effective dose equivalent (for external exposures) and the committed effective dose equivalent (for internal exposures). (7-1-25) 14. Unimportant Quantities of Source Material. Unimportant quantities of source materials defined by the U.S. Nuclear Regulatory Commission (10 CFR 40.13). (7-1-25) 011. -- 018. (RESERVED)
