Louisiana Administrative Code › Title 33 - ENVIRONMENTAL QUALITY › Part XV - Radiation Protection › Chapter 5 - Radiation Safety Requirements for Industrial Radiographic Operations › Section XV-503 - Definitions

Current through Register Vol. 50, No. 6, June 20, 2024
A. As used in this
				Chapter, the following definitions apply.
Annual Refresher Safety Training
- a review
				  conducted or provided by the licensee for its employees on radiation safety
				  aspects of industrial radiography. The review may include, as appropriate, the
				  results of internal inspections, new procedures or equipment, new or revised
				  regulations, and accidents or errors that have been observed, and should also
				  provide opportunities for employees to ask safety questions.
Associated Equipment
- 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 it is used as an exposure head).
Cabinet Radiography
- industrial radiography
				  conducted in an enclosure or cabinet so shielded that every location on the
				  exterior meets the conditions specified in LAC 33:XV.421 for an unrestricted
				  area.
Cabinet X-Ray System
- an X-ray system with
				  the X-ray tube installed in an enclosure (hereinafter termed
Cabinet
) that, independently of existing architectural
				  structures except the floor on which it may be placed, is intended to contain
				  at least that portion of a material being irradiated, provides radiation
				  attenuation, and excludes personnel from its interior during generation of
				  X-radiation. Included are all 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.
Certified Cabinet X-Ray System
- a cabinet
				  X-ray system that has been certified in accordance with
				  21
				  CFR 1010.2 as having been manufactured,
				  assembled, and maintained pursuant to the provisions of
				  21 CFR
				  1020.40.
Certifying Entity
- an independent
				  certifying organization meeting the requirements in
				    10 CFR
				  34   Appendix A, or an agreement state meeting
				  the requirements in 10 CFR
				  34 Appendix A, Parts II and III.
Collimator
-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 (Drive) Cable
-the cable that is
				  connected to the source assembly and used to drive the source to and from the
				  exposure location.
Control Drive Mechanism
-a device that
				  enables the source assembly to be moved to and from the exposure device.
Control Tube
- a protective sheath for
				  guiding the control cable. The control tube connects the control drive
				  mechanism to the radiographic exposure device.
Enclosed Radiography
- industrial
				  radiography conducted in an enclosed cabinet or room, including cabinet
				  radiography and shielded room radiography.
Exposure Head
- 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
- a facility where licensed
				  material may be stored or used and from which equipment is dispatched.
Guide Tube (Projection Sheath)
- 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
- experience in all of
				  those areas considered to be directly involved in the radiography
				  process.
Independent Certifying Organization
-an
				  independent organization that meets all of the criteria of LAC
				  33:XV.599.Appendix A, B and C.
Industrial Radiography
-the examination of
				  the structure of materials by nondestructive methods utilizing ionizing
				  radiation to produce radiographic images.
Instructor
- any individual who has been
				  authorized by the department to provide instruction to radiographer trainees in
				  accordance with LAC 33:XV.575.A.
Lay-Barge Radiography
-industrial
				  radiography performed on any water vessel used for laying pipe.
Lixiscope
- a portable light-intensified
				  imaging device using a sealed source.
Offshore Platform Radiography
-industrial
				  radiography conducted from a platform over a body of water.
Permanent Radiographic Installation
-an
				  enclosed shielded room, cell, or vault, not located at a temporary jobsite, in
				  which radiography is performed.
Personal Supervision
- guidance and
				  instruction provided to a radiographer trainee by an instructor who is
				  physically present while sources of radiation are being used.
Practical Examination
- a demonstration
				  through practical application of the safety rules and principles in industrial
				  radiography, including use of all appropriate equipment and procedures.
Radiation Safety Officer for Industrial
				  Radiography
- an individual with the responsibility for the overall
				  radiation safety program on behalf of the licensee and who meets the
				  requirements of LAC 33:XV.573.E.
Radiographer
