Sec. 3. The following definitions apply throughout this article:

(1) "Civil penalty" means any monetary penalty levied on a licensee or registrant because of violations of statutes, regulations, licenses, or registration certificates, but does not include criminal penalties.

(2) "Closure" or "site closure" means all activities performed at a waste disposal site, such as stabilization and contouring, to ensure that the site is in a stable condition so that only minor custodial care, surveillance, and monitoring are necessary at the site after termination of a licensed operation.

(3) "Decommissioning" means final operational activities at a facility to dismantle site structures, decontaminate site surfaces and remaining structures, stabilize and contain residual radioactive material, and carry out any other activities to prepare the site for postoperational care.

(4) "Department" means the department of homeland security established by IC 10-19-2-1.

(5) "Disposal of low-level radioactive waste" means the isolation of that waste from the biosphere by emplacement in a land burial facility.

(6) "General license" means a license effective under regulations promulgated by the department, without the filing of an application with the department, or the issuance of licensing documents to particular persons to transfer, acquire, own, possess, or use quantities of, or devices or equipment using, radioactive material.

(7) "Government agency" means any board, commission, department, agency, authority, or other entity, by whatever name designated, exercising a portion of the executive, administrative, or legislative power of the state.

(8) "High-level radioactive waste" means:

(A) irradiated reactor fuel;

(B) liquid wastes resulting from the operation of the first cycle solvent extraction system, or equivalent, and the concentrated wastes from subsequent extraction cycles, or equivalent, in a facility for reprocessing irradiated reactor fuel; and

(C) solids into which those liquid wastes have been converted.

(9) "Ionizing radiation" means gamma rays and x-rays, alpha and beta particles, high-speed electrons, neutrons, protons, and other nuclear particles, but not sound or radio waves, or visible, infrared, or ultraviolet light.

(10) "Low-level radioactive waste" means radioactive waste not classified as high-level radioactive waste, transuranic waste, spent nuclear fuel, or byproduct material.

(11) "Nonionizing radiation" means the following:

(A) Any electromagnetic radiation, other than ionizing electromagnetic radiation.

(B) Any sonic, ultrasonic, or infrasonic wave.

(12) "Radiation" means ionizing radiation and nonionizing radiation.

(13) "Radiation generating equipment" means a manufactured product or device, or component part of the product or device, or a machine or system that during operation can generate or emit radiation, except those that emit radiation only from radioactive material.

(14) "Radioactive material" means material (solid, liquid, or gas) that emits ionizing radiation spontaneously. It includes accelerator produced, byproduct, naturally occurring, source, and special nuclear materials.

(15) "Registration" means registration with the department in accordance with the Indiana Administrative Procedure Act, IC 4-21.5 and IC 4-22.

(16) "Source material milling" means any processing of ore, including underground solution extraction of unmined ore, primarily for the purpose of extracting or concentrating uranium or thorium that results in the production of source material mill tailings.

(17) "Source material mill tailings" means the tailings or wastes produced by the extraction or concentration of uranium or thorium from any ore processed primarily for its source material content, including discrete surface wastes resulting from underground solution extraction processes, but not including underground ore bodies depleted by those solution extraction processes.

(18) "Sources of radiation" means collectively, radioactive material and radiation generating equipment.

(19) "Specific license" means a license, issued to a named person upon application filed under the regulations promulgated under this article, to use, manufacture, produce, transfer, receive, acquire, or possess quantities of, or devices or equipment using, radioactive material.

(20) "Spent nuclear fuel" means irradiated nuclear fuel that has undergone at least one (1) year of decay since being used as a source of energy in a power reactor. Spent fuel includes the special nuclear material, byproduct material, source material, and other radioactive material associated with fuel assemblies.

(21) "Transuranic waste" means radioactive waste containing alpha emitting transuranic elements, with radioactive half-lives greater than five (5) years, exceeding ten (10) nanocuries per gram.
