(a) Definitions. As used in this section the
				  following terms have these defined meanings:
(1) Associated equipment--equipment used in
				  conjuction with a radiographic exposure device to make radiographic exposures
				  that drives, guides or comes in contact with the source, (i.e.,guide tube,
				  control tube, crank, removable source stop, "J" tube).
(2) Collimator--a device used to limit the
				  size, shape, and direction of the primary radiation beam.
(3) Control (crank-out) device--the control
				  cable, the protective sheath and control drive mechanism used to move the
				  sealed source from its shielded position in the radiographic device or camera
				  to an unshielded position outside the device for the purpose of making a
				  radiographic exposure.
(4) Control
				  tube--protective sheath for guiding the control cable. The control tube
				  connects the control drive mechanism to the radiographic exposure
				  device.
(5) 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.)
(6) Field examination--a demonstration of
				  practical application of the principles learned in the classroom that should
				  include use of all appropriate equipment and procedures.
(7) Periodic training--a periodic review
				  conducted or provided by the licensee for its employees on radiation safety
				  aspects of radiography. The review may include, as appropriate, the results of
				  internal inspections, new procedures or equipment, accidents or errors that
				  have been observed, and opportunities for employees to ask safety
				  questions.
(8) Permanent
				  radiographic installation--an enclosed shielded room, cell, or vault in which
				  radiography is performed.
(9)
				  Projection sheath (guide tube)--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 or working position.
(10) Radiographer--any individual who has
				  successfully completed the training and testing requirements specified in this
				  section for radiographers, and who conducts or personally supervises
				  radiographic operations at a site.
(11) Radiographer's assistant--any individual
				  who has successfully completed the training and testing requirements specified
				  in this section for a radiographer's assistant, and who must use radiographic
				  exposure devices, sealed sources or related handling tools, or radiation survey
				  instruments under the personal supervision of a radiographer.
(12) Radiographic exposure device--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 radiographic exposure,
				  (i.e., a camera, or a projector).
(13) Radiography--the examination of the
				  structure of materials by nondestructive methods, utilizing sealed sources of
				  radioactive materials.
(14) Sealed
				  source--any radioactive material that is encased in a capsule designed to
				  prevent leakage or escape of the radioactive material.
(15) Shielded position--the location within
				  the radiographic exposure device or source changer where the sealed source is
				  secured and restricted from movement. (In this position the radiation exposure
				  will be at a minimum. This position incorporates maximum shielding for the
				  radioactive source.)
(16) Source
				  assembly--consists of the sealed source and a connector. May also include a
				  stop ball used to secure the source in the shielded position. The connector
				  attaches to the control cable.
(17)
				  Source changer--a device designed and used for replacement of sealed sources in
				  radiographic exposure devices, including those also used for transporting and
				  storage of sealed sources.
(18)
				  Storage area--any location, facility, 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.
(19) Storage
				  container--a device in which sealed sources are stored.
(20) Temporary jobsite--a place where
				  licensed materials are present for the purpose of performing radiography, other
				  than any permanent radiographic installation.
