				employees on radiation safety aspects of industrial radiography. The review may
				include, as appropriate, the results of internal inspections, new procedures or

				observed, and should also provide opportunities for employees to ask safety
				questions.
(2)
"Associated
				equipment"
means equipment that is used in conjunction with a
				radiographic exposure device to make radiographic exposures which drives,
				guides, or comes in contact with the source, for example guide tube, control
				tube, control (drive) cable, removable source stop, "J" tube and collimator
				when it is used as an exposure head.
(3)
"Certifying entity"
means an
				independent certifying organization meeting the requirements in WAC
				246-243-250 Appendix C or an
				agreement state meeting the requirements in WAC
				246-243-250 Appendix C,
				subsections (2) and (3).
(4)
"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.
(5)
"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.
(6)
"Control drive
				mechanism"
means a device that enables the source assembly to be moved
				to and from the exposure device.
(7)
"Control tube"
means a
				protective sheath for guiding the control cable. The control tube connects the
				control drive mechanism to the radiographic exposure device.
(8)
"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.)
(9)
"Field station"
means a
				facility where licensed material may be stored or used and from which equipment
				is dispatched.
(10)
"Guide
				tube (projection sheath)"
means a flexible or rigid 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.
(11)
"Hands-on experience"
means
				experience in all of those areas considered to be directly involved in the
				radiography process.
(12)
"Independent certifying organization"
means an independent
				organization that meets all of the criteria of WAC
				246-243-250 Appendix C.
(13)
"Industrial radiography"
means the examination of the macroscopic structure of materials by
				nondestructive methods utilizing sources of radiation to make radiographic
				images. Industrial radiography as used in this chapter does not include well
				logging operations.
(14)
"Lay-barge radiography"
means industrial radiography performed on
				any water vessel used for laying pipe.
(15)
"Offshore platform
				radiography"
means industrial radiography conducted from a platform over
				a body of water.
(16)
"Permanent radiographic installation"
means an enclosed shielded
				room, cell or vault, not located at a temporary job site, in which radiography
				is performed, regardless of ownership.
(17)
"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.
(18)
"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 WAC
				246-243-047.
(19)
"Radiographer"
means any
				individual who performs or who, in attendance at the site where sources of
				radiation are being used, personally supervises industrial radio-graphic
				operations and who is responsible to the licensee for assuring compliance with
				the requirements of these regulations and all license conditions.
(20)
"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.
(21)
"Radiographer's assistant"
means any individual who, under the personal supervision of a radiographer,
				uses sources of radiation, related handling tools, or radiation survey
				instruments in industrial radiography.
(22)
"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.
(23)
"Radiographic operations"
means all activities associated with the presence of radioactive sources in a
				radio-graphic exposure device during use of the device or transport (except
				when being transported by a common or contract carrier), to include surveys to
				confirm the adequacy of boundaries, setting up equipment and any activity
				inside restricted area boundaries.
(24)
"S-tube"
means a tube
				through which the radioactive source travels when inside a radiographic
				exposure device.
(25)
"Shielded position"
means the location within the radiographic
				exposure device or source changer where the sealed source is secured and
				restricted from movement.
(26)
"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.
(27)
"Source changer"
means 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.
(28)
"Storage area"
means 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.
(29)
"Storage container"
means a container in which sealed sources are
				secured and stored.
(30)
"Temporary job site"
means a location where radiographic
				operations are conducted and where licensed material may be stored other than
				those locations of use authorized on the license.
(31)
"Underwater radiography"
means industrial radiography performed when the radiographic exposure device or
				related equipment are beneath the surface of the water.
