				Part 34 or an Agreement State meeting the requirements in appendix A, Parts II and
				III of 10 CFR Part 34.
5.3.6 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

				means the cable that is connected to the source assembly and used to drive the
				source to and from the exposure location.
5.3.8 Control drive mechanism means a device that
				enables the source assembly to be moved to and from the exposure device.
5.3.9 Control tube means a protective sheath for
				guiding the control cable. The control tube connects the control drive mechanism to
				the radiographic exposure device.
5.3.10
				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.)
5.3.11 Field station means a
				facility where licensed material may be stored or used and from which equipment is
				dispatched.
5.3.12 Gray means the SI
				unit of absorbed dose. One gray is equal to an absorbed dose of 1 Joule/kilogram. It
				is also equal to 100 rads.
5.3.13 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.
5.3.14 Hands-on experience means experience in all
				of those areas considered to be directly involved in the radiography
				process.
5.3.15 Independent certifying
				organization means an independent organization that meets all of the criteria of
				Appendix A, 10 CFR Part 34.
5.3.16
				Industrial radiography (radiography) means an examination of the structure of
				materials by nondestructive methods, utilizing ionizing radiation to make
				radiographic images.
5.3.17 Lay-barge
				radiography means industrial radiography performed on any water vessel used for
				laying pipe.
5.3.18 Offshore platform
				radiography means industrial radiography conducted from a platform over a body of
				water.
5.3.19 Permanent radiographic
				installation means an enclosed shielded room, cell, or vault, not located at a
				temporary jobsite, in which radiography is performed.
5.3.20 Practical Examination means a demonstration
				through practical application of the safety rules and principles in industrial
				radiography including use of all appropriate equipment and procedures.
5.3.21 Radiation Safety Officer for industrial
				radiography means an individual with the responsibility for the overall radiation
				safety program on behalf of the licensee and who meets the requirements of
				RHA 5.22.
5.3.22 Radiographer means any individual who
				performs or who, in attendance at the site where the sealed source or sources are
				being used, personally supervises industrial radiographic operations and who is
				responsible to the licensee for assuring compliance with the requirements of the
				Department's regulations and the conditions of the license.
5.3.23 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.
5.3.24 Radiographer's
				assistant means any individual who under the direct supervision of a radiographer,
				uses radiographic exposure devices, sealed sources or related handling tools, or
				radiation survey instruments in industrial radiography.
5.3.25 Radiographic exposure device (also called a
				camera, or a projector) 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.
5.3.26
				Radiographic operations means all activities associated with the presence of
				radioactive sources in a radiographic exposure device during use of the device or
				transport (except when being transported by a common or contract transport), to
				include surveys to confirm the adequacy of boundaries, setting up equipment and any
				activity inside restricted area boundaries.
5.3.27 S-tube means a tube through which the
				radioactive source travels when inside a radiographic exposure device.
5.3.28 Sealed source means any radioactive
				material that is encased in a capsule designed to prevent leakage or escape of the
				radioactive material.
5.3.29 Shielded
				position means the location within the radiographic exposure device or source
				changer where the sealed source is secured and restricted from movement.
5.3.30 Sievert means the SI unit of any of the
				quantities expressed as dose equivalent. The dose equivalent in sieverts is equal to
				the absorbed dose in grays multiplied by the quality factor (1 Sv = 100
				rems).
5.3.31 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 also include a stop ball used to
				secure the source in the shielded position.

				used for replacement of sealed sources in radiographic exposure devices, including
				those also used for transporting and storage of sealed sources.

				or vehicle which is used to store or to secure a radiographic exposure device, a
				storage container, or a sealed source when it is not in use and which is locked or
				has a physical barrier to prevent accidental exposure, tampering with, or
				unauthorized removal of the device, container, or source.
5.3.34 Storage container means a container in
