Arizona Administrative Code › Title 9 - HEALTH SERVICES › Chapter 7 - DEPARTMENT OF HEALTH SERVICES - RADIATION CONTROL › Article 5 - SEALED SOURCE INDUSTRIAL RADIOGRAPHY › Section R9-7-501 - Definitions

Current through Register Vol. 30, No. 28, July 12, 2024
"Access panel" means any panel that is designed to be removed
				  or opened for maintenance or service purposes, opened using tools, and used to
				  provide access to the interior of the cabinet x-ray unit.
"Annual refresher safety training" means a review conducted
				  or provided by the licensee for its employees on radiation safety aspects of
				  industrial radiography. The review shall include, as applicable, the results of
				  internal inspections, new procedures or equipment, new or revised state rules,
				  accidents or errors that have occurred, and provide opportunities for employees
				  to ask safety questions.
"Aperture" means any opening in the outside surface of the
				  cabinet x-ray unit, other than a port, which remains open during generation of
				  x-radiation.
"Associated equipment" means equipment used in conjunction
				  with a radiographic exposure device that drives, guides, or comes in contact
				  with the source.
"Certifying entity" means an independent certifying
				  organization that complies with the requirements in Appendix A of this Article,
				  or requirements of the NRC or another Agreement State, that are equivalent to
				  the requirements in parts II and III of Appendix A.
"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 positioned to
				  make a radiographic exposure.
"Control (drive) 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 to and from 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.
"Door" means any barrier that is designed to be movable or
				  opened for routine operation purposes, not opened using tools, and used to
				  provide access to the interior of the cabinet x-ray unit.
"Exposure head" means a device that places the gamma
				  radiography sealed source in a selected working position.
"Ground fault" means an accidental electrical grounding of an
				  electrical conductor.
"Guide tube (projection sheath)" means a flexible or rigid
				  tube (i.e., "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 accumulation of knowledge or
				  skill in any area relevant to radiography.
"Independent certifying organization" means an independent
				  organization that meets all of the requirements in Appendix A.
"Lay-barge radiography" means industrial radiography
				  performed on any water vessel used for laying pipe.
"Port" means any opening in the outside surface of the
				  cabinet x-ray unit that is designed to remain open, during generation of
				  x-rays, for conveying material being irradiated into and out of the cabinet, or
				  for partial insertion of an object for irradiation whose dimensions do not
				  permit complete insertion into the cabinet x-ray unit.
"Practical examination" means a demonstration, through
				  practical application of safety rules and principles of industrial radiography,
				  including use of all radiography equipment and knowledge of radiography
				  procedures.
"Radiographer certification" means written approval received
				  from a certifying entity stating that an individual has satisfactorily met
				  certain established radiation safety, testing, and experience criteria.
"Radiographic exposure device" means any x-ray machine used
				  for purposes of making an industrial radiographic exposure or a device that
				  contains a sealed source, and the sealed source or its shielding may be moved
				  or otherwise changed from a shielded to an unshielded position for purposes of
				  making an industrial radiographic exposure.
"Radiographic operations" means all activities associated
				  with the presence of radiation sources in a radiographic exposure device during
				  use of the device or transport (except when the device is being transported by
				  a common or contract carrier). This includes performing surveys to confirm the
				  adequacy of boundaries, setting up equipment, and conducting any activity
				  inside restricted area boundaries.
"S-tube" means a tube through which a radioactive source
				  travels when the source is inside a radiographic exposure device.
"Source assembly" means an assembly that consists of a sealed
				  source and a connector that attaches the source to a control cable. The source
				  assembly may also include a stop ball used to secure the source in the shielded
				  position.
"Underwater radiography" means industrial radiography
				  performed when a radiographic exposure device is beneath the surface of
				  water.
