6 Colo. Code Regs. § 1007-1-5.2
As used in this part, these terms have the definitions set forth as follows:
"Annual refresher safety training" means a review conducted or provided by the licensee or registrant for its employees on radiation safety aspects of industrial radiography. The review shall include, as a minimum, any results of internal inspections, new procedures or equipment, new or revised regulations, and accidents or errors that have been observed. The review shall also provide opportunities for employees to ask safety questions.
"Associated equipment" means equipment that is used in conjunction with a radiographic exposure device to make radiographic exposures that drives, guides, or comes in contact with the source (e.g., guide tube, control tube, control (drive) cable, removable source stop, "J" tube and collimator when used as an exposure head).
"Cabinet radiography" means industrial radiography conducted in an enclosure or cabinet so shielded that every location on the exterior meets the dose limits for individual members of the public as specified in 4.14.
"Cabinet x-ray system" means an x-ray system with the x-ray tube installed in an enclosure, hereinafter termed a cabinet that is independent of existing architectural structures except the floor. The cabinet x-ray system is intended to contain at least that portion of a material being irradiated, provide radiation attenuation, and exclude personnel from its interior during generation of radiation. This definition includes x-ray systems designed primarily for the inspection of carry on baggage at airline, railroad, and bus terminals, and in similar facilities. An x-ray tube used within a shielded part of a building, or x-ray equipment that may temporarily or occasionally incorporate portable shielding, is not considered a cabinet x-ray system.
"Camera" (see "radiographic exposure device").
Certifiable cabinet x-ray system" means an existing uncertified x-ray system that has been modified to meet the certification requirements specified in 21 CFR Part 1020.40.
"Certified cabinet x-ray system" means an x-ray system that has been certified in accordance with 21 CFR Part 1010.2 , as being manufactured and assembled pursuant to the provisions of 21 Part CFR 1020.40.
"Certifying entity" means an independent certifying organization meeting the requirements in Appendix 5A or a state regulatory program meeting the requirements in Appendix 5A, Sections 5A.2 and 5A.3.
"Collimator" means a radiation shield that is placed on the end of the guide tube or directly onto a radiographic exposure device to restrict the size of the radiation beam when the sealed source is cranked into position to make a radiographic exposure.
"Control cable" means the cable that is connected to the source assembly and used to drive the source to and from the exposure location.
"Control drive mechanism" means a device that enables the source assembly to be moved into and out of the exposure device.
"Control tube" means a protective sheath for guiding the control cable. The control tube connects the control drive mechanism to the radiographic exposure device.
"Drive cable" (see "control cable").
"Exposure head" means a device that locates the gamma radiography sealed source in the selected working position. An exposure head is also known as a source stop.
"Field station" means a facility from which sources of radiation may be stored or used and from which equipment is dispatched.
"Guide tube" means a flexible or rigid tube, or "J" tube, for guiding the source assembly and the attached control cable from the exposure device to the exposure head. The guide tube may also include the connections necessary for attachment to the exposure device and to the exposure head.
"Hands-on experience" means experience in all of those areas considered to be directly involved in the radiography process.
"Independent certifying organization" means an independent organization that meets all of the criteria of Appendix 5A.
"Industrial radiography" means an examination of the structure of materials by the nondestructive method of utilizing ionizing radiation to make radiographic images.
"Lay-barge radiography" means industrial radiography performed on any water vessel used for laying pipe.
"Offshore platform radiography" means industrial radiography conducted from a platform over a body of water.
"Permanent radiographic installation" means an enclosed shielded room, cell, or vault, not located at a temporary jobsite, in which radiography is performed.
"Pigtail" (see "source assembly").
"Pill" (see "sealed source").
"Practical examination" means a demonstration through application of the safety rules and principles in industrial radiography including use of all procedures and equipment to be used by radiographic personnel.
"Projection sheath" (see "guide tube").
"Projector" (see "radiographic exposure device").
"Radiation safety officer for industrial radiography" means an individual with the responsibility for the overall radiation safety program on behalf of the licensee or registrant and who meets the requirements of 5.16.
"Radiographer" means any individual who meets the requirements of Appendix 5C and performs industrial radiography or who, in attendance at the site where the sources of radiation are being used for industrial radiography, personally supervises industrial radiographic operations and is responsible to the licensee or registrant for assuring compliance with the requirements of the Department's regulations and the conditions of the license or registration.
"Radiographer certification" means written approval received from a certifying entity stating that an individual has satisfactorily met the radiation safety, testing, and experience criteria in 5.17.
"Radiographer's assistant" means any individual who meets the requirements of Appendix 5D and who under the direct supervision of a radiographer, uses radiographic exposure devices, sources of radiation, related handling tools, or radiation survey instruments in industrial radiography.
"Radiographic exposure device" means any instrument containing a sealed source fastened or contained therein, in which the sealed source or shielding thereof may be moved, or otherwise changed, from a shielded to unshielded position for purposes of making a radiographic exposure.
"Radiographic operations" means all activities performed with a radiographic exposure device, or with a radiation-producing machine. Such activities include: using; transporting except by common or contract carriers; storing at a temporary job site; performing surveys to confirm the adequacy of boundaries; setting up equipment; and any activity inside restricted area boundaries. Transporting a radiation machine is not considered a radiographic operation.
"Radiography" (see "industrial radiography").
"S-tube" means a tube through which the radioactive source travels when inside a radiographic exposure device.
"Shielded position" means the location within the radiographic exposure device, source changer, or storage container that, by manufacturer's design, is the proper location for storage of the sealed source.
"Source assembly" means an assembly that consists of the sealed source and a connector that attaches the source to the control cable. The source assembly may include a ballstop to secure the source in the shielded position.
"Source changer" means a device designed and used for replacement of sealed sources in radiographic exposure devices. A source changer may also be used for transporting and storing sealed sources.
"Storage area" means any location, facility, or vehicle that is used to store and secure a radiographic exposure device, a radiation machine, or a storage container when it is not used for radiographic operations. Storage areas are locked or have a physical barrier to prevent accidental exposure, tampering, or unauthorized removal of the device, machine, or container.
"Storage container" means a device in which sealed sources or radiation machines are secured and stored.
"Temporary jobsite" means a location where radiographic operations are performed and where sources of radiation may be stored other than the location(s) of use authorized on the license or registration.
"Underwater radiography" means radiographic operations performed when the radiographic exposure device or radiation machine and/or related equipment are beneath the surface of the water.
