North Carolina Administrative Code › Title 10A - HEALTH AND HUMAN SERVICES › Chapter 15 - RADIATION PROTECTION › Section .0800 - REQUIREMENTS FOR NON-HUMAN USE OF RADIATION GENERATING DEVICES › Section 15 .0802 - DEFINITIONS

Current through Register Vol. 39, No. 2, July 15, 2024
In addition to terms found in Rule.0104 of this Chapter the
				  following definitions shall apply to this Section:
(1) "Accredited bomb squad" means a law
				enforcement agency utilizing certified bomb technicians.
(2) "Analytical RGD equipment" means
				equipment that uses electronic means to generate ionizing radiation for the
				purpose of examining the microstructure of materials, i.e. x-ray diffraction
				and x-ray spectroscopy.
(3)
				"Analytical RGD system" means a group of local and remote components utilizing
				x-rays to determine the elemental composition or to examine the microstructure
				of materials.
(4) "Bomb detection
				RGDs" means RGDs used for the sole purpose of remotely detecting explosive
				devices.
(5) "Certified bomb
				technician" means a member of an accredited bomb squad who has completed the
				FBI Hazardous Devices School. Information pertaining to this program can be
				found on the school website at
http://www.fbi.gov/about-us/cirg/hazardous-devices
.
(6) "Certifiable cabinet x-ray
				system" means an existing uncertified RGD that has been modified to meet the
				certification requirements specified in
				21 CFR
				1020.40 as incorporated by reference in Rule
				.0117 of this Chapter.
(7)
				"Certified cabinet x-ray system" means an RGD utilized in an enclosed,
				interlocked cabinet, such that the radiation machine will not operate unless
				all openings are securely closed. These systems shall be certified in
				accordance with 21 CFR
				1010.2 as incorporated by reference in
				Rule.0117 of this Chapter, as being manufactured and assembled pursuant to the
				provisions of 21 CFR
				1020.40 as incorporated by reference in
				Rule.0117 of this Chapter.
(8)
				"Collimator" means a device or mechanism by which the x-ray beam is restricted
				in size.
(9) "Control panel" means
				that part of the x-ray control upon which are mounted the switches, knobs,
				pushbuttons, and other hardware necessary for manually setting the technique
				factors.
(10) "Electron Beam
				Device" means any device using electrons below 1MeV to heat, join, or otherwise
				irradiate materials.
(11) "Enclosed
				beam RGD" means an RGD with all possible x-ray beam paths contained in a
				chamber, coupled chambers, or other beam-path-confinement devices to prevent
				any part of the body from intercepting the beam during normal operations.
				Normal access to the primary beam path, such as a sample chamber door, shall be
				interlocked with the high voltage of the x-ray tube or the shutter for the beam
				to be considered "enclosed." An open-beam device placed in an interlocked
				enclosure is considered an "enclosed beam" unless there are provisions for
				routine bypassing of the interlocks.
(12) "Fail-safe characteristics" means a
				design feature that causes the radiation beam to terminate, port shutters to
				close, or otherwise prevents emergence of the primary beam, upon the failure of
				a safety or warning device. For example, if an "X-ray On" light indicator or
				shutter indicator or interlock fails, the radiation beam shall
				terminate.
(13) "Hand-held x-ray
				system" means any device or equipment that is portable and used for similar
				purposes as analytical RGD equipment.
(14) "Hybrid gauge" means an x-ray gauge
				device utilizing both x-ray and radioactive sources.
(15) "Industrial radiography" means RGDs used
				to make radiographic images to examine the structure of materials by
				nondestructive methods. These RGDs shall not be contained in a cabinet and are
				not permanent installations.
(16)
				"Ion implantation equipment, low-energy" means any closed device operating
				below 1MeV used to accelerate elemental ions and implant them in other
				materials.
(17) "Leakage radiation"
				means radiation emanating from the source assembly housing except for:
(A) the primary beam;
(B) scatter radiation emanating from other
				components (e.g., shutter or collimator); and
(C) radiation produced when the beam on
				switch or timer is not activated.
