Washington Administrative Code › Title 246 - Health, Department of › RADIATION › Chapter 246-237 - Radiation protection Physical protection of category 1 and category 2 quantities of radioactive material › Section 246-237-010 - Definitions, abbreviations, and acronyms

Current through Register Vol. 24-14, July 15, 2024
The definitions, abbreviations, and acronyms in this section
				  and in WAC 246-220-010 apply throughout this chapter unless the context clearly
				  indicates otherwise:
(1) "Access
				control" means a system for allowing only approved individuals to have
				unescorted access to the security zone and for ensuring that all other
				individuals are subject to escorted access.
(2) "Act" means the Atomic Energy Act of
				1954, including any amendments thereto.
(3) "Aggregated" means accessible by the
				breach of a single physical barrier that would allow access to radioactive
				material in any form, including any devices that contain the radioactive
				material, when the total activity equals or exceeds a Category 2 quantity of
				radioactive material.
(4)
				"Agreement state" means any state with which the Atomic Energy Commission or
				the NRC has entered into an effective agreement under subsection 274b of the
				act. Nonagreement state means any other state.
(5) "Approved individual" means an individual
				whom the licensee has determined to be trustworthy and reliable for unescorted
				access in accordance with WAC 246-237-021 through 246-237-033 and who has
				completed the training required by WAC 246-237-043(3).
(6) "Background investigation" means the
				investigation conducted by a licensee or applicant to support the determination
				of trustworthiness and reliability.
(7) "Becquerel (Bq)" means the SI unit of
				activity. One becquerel is equal to one disintegration or transformation per
				second (s-1).
(8) "By-product material" means:
(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 using special nuclear
				material;
(b) The tailings or
				wastes 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;
(c)
(i) 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
(ii) Any material that:
(A) Has been made radioactive by use of a
				particle accelerator; and
(B) Is
				produced, extracted, or converted after extraction, before, on, or after August
				8, 2005, for use for a commercial, medical, or research activity; and
(d) Any discrete source
				of naturally occurring radioactive material, other than source material, that:
(i) The NRC, 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 radium-226 to the public health and safety or the common
				defense and security; and
(ii)
				Before, on, or after August 8, 2005, is extracted or converted after extraction
				for use in a commercial, medical, or research activity.
