2023 Colorado Revised Statutes › Title 25 - PUBLIC HEALTH AND ENVIRONMENT (§§ 25-1-101 — 25-59-106) › ENVIRONMENTAL CONTROL (§§ 25-6.5-101 — 25-18.9-105) › Article 11 - RADIATION CONTROL (§§ 25-11-101 — 25-11-305) › Part 1 - GENERAL PROVISIONS (§§ 25-11-101 — 25-11-114) › Section 25-11-101 - Definitions

As used in this part 1, unless the context otherwise requires:
(1)
"Byproduct 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 are not "byproduct material".
(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 United States 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 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.
(1.5)
"Civil penalty" means a monetary penalty levied against a licensee or registrant because of a violation of a statute, rule, license, or registration certificate. "Civil penalty" does not include any criminal penalty levied under section
25-1-114
or
25-11-107 (3)
.
(2)
"Department" means the department of public health and environment.
(2.5)
"Mammographer" means a person who operates a machine source of radiation, commonly known as an "X-ray machine", in the conduct of a mammography exam.
(2.7)
"Naturally occurring radioactive material" means any nuclide that is radioactive in its natural physical state and is not manufactured. "Naturally occurring radioactive material" does not include source material, special nuclear material, byproduct material, or by-products of fossil fuel combustion, including bottom ash, fly ash, and flue-gas emission by-products.
(3)
"Radiation" means ionizing radiation, which includes gamma rays, X rays, alpha particles, beta particles, high-speed electrons, high-speed neutrons, high-speed protons, and other high-speed nuclear particles.
(4)
"Radiation machine" means a device capable of producing radiation; except that "radiation machine" does not include a device with radioactive material as its only source of radiation.
(5)
"Radioactive" means emitting radiation.
(6)
"Radioactive material" means any material, whether solid, liquid, or gas, that emits radiation spontaneously.
(6.4)
(a)
"Source material" means uranium, thorium, or any combination of uranium and thorium in any physical or chemical form, including ores that contain, by weight, one-twentieth of one percent or more of uranium, thorium, or any combination of uranium and thorium.
(b)
"Source material" does not include special nuclear material.
(6.7)
(a)
"Special nuclear material" means:
(I)
Plutonium, uranium-233, uranium enriched in the isotope 233 or in the isotope 235, and any other material that the United States nuclear regulatory commission, pursuant to section 51 of the federal "Atomic Energy Act of 1954", as amended,
42 U.S.C. sec. 2071
, determines to be special nuclear material; or
(II)
Any material artificially enriched by any of the material specified in subparagraph (I) of this paragraph (a).
(b)
Notwithstanding any other provision of this subsection (6.7), "special nuclear material" does not include source material.
(7)
"Specific license" means a license issued to a person to use, manufacture, produce, transfer, receive, acquire, own, or possess quantities of, or devices or equipment utilizing, radioactive materials occurring naturally or produced artificially.
(8)
"State board" means the state board of health created in section
25-1-103
.
