SUBCHAPTER FLICENSE REGULATIONS
RULE §289.255Radiation Safety Requirements and Licensing and Registration Procedures for Industrial Radiography

  (22) Lay-barge radiography--Industrial radiography performed on any water vessel used for laying pipe.

  (23) Lock-out survey--A radiation survey performed to determine that a sealed source is in its fully shielded position before moving the radiographic exposure device or source changer to a different temporary job site or before securing the radiographic exposure device or source changer against unauthorized removal.

  (24) Offshore--Within the territorial waters of the State of Texas. The territorial waters of Texas extend to the three marine league line or nine nautical miles from the Texas coast.

  (25) On-the-job training (hands-on experience)--Experience in all of the areas considered to be directly involved in the radiography process. The hours of on-the-job training do not include safety meetings, classroom training, travel, darkroom activities, film development and interpretation, or use of a cabinet x-ray unit.

  (26) Permanent radiographic installation--A shielded room, cell, or vault, not located at a temporary jobsite, in which radiography is performed and meets the criteria of subsection (n) of this section.

  (27) Permanent storage site--Any location that is specifically named on a license or certificate of registration and that is used only for storage of sources of radiation.

  (28) Personal supervision--Guidance and instruction provided to a radiographer trainee by a radiographer trainer who is present at the site, in visual contact with the trainee while the trainee is using sources of radiation, associated equipment, and survey meters, and in such proximity that immediate assistance can be given if required.

  (29) Pipeliners--A directional beam radiographic exposure device.

  (30) Platform radiography--Industrial radiography performed on an offshore platform or other structure over a body of water.

  (31) Practical examination--A demonstration through practical application of the safety rules and principles in industrial radiography including use of all appropriate equipment and procedures.

  (32) Radiation safety officer (RSO)--An individual named by the licensee or registrant who has a knowledge of, responsibility for, and authority to enforce appropriate radiation protection rules, standards, and practices on behalf of the licensee or registrant and who meets the requirements of subsection (e)(4) of this section.

  (33) Radiographer--Any individual who has successfully completed the training, testing, and documentation requirements of subsection (e)(2)(A) of this section and who is responsible to the licensee or registrant for assuring compliance with the requirements of the agency's regulations and conditions of the license or certificate of registration. These individuals may be referred to as certified industrial radiographers or certified radiographers. The individual may also:

    (A) perform industrial radiographic operations; or

    (B) be in attendance at the site where the sources of radiation are being used.

  (34) Radiographer certification--Written approval received from a certifying entity stating that an individual has satisfactorily met certain established radiation safety, testing, and experience criteria.

  (35) Radiographer trainee--Any individual who has successfully completed the training and documentation requirements of subsection (e)(1)(A) of this section and who shall use sources of radiation and associated equipment or radiation survey instruments under the personal supervision of a radiographer trainer.

  (36) Radiographer trainer--A radiographer who instructs and supervises radiographer trainees during on-the-job training and who meets the requirements of subsection (e)(3) of this section.

  (37) 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 a radiographic exposure (e.g., camera).

  (38) Radiographic operations--All activities associated with the presence of x-ray machines or radioactive sources in a radiographic exposure device during the use of the machine or device or transport (except when being transported by a common or contract transport). Radiographic operations include surveys to confirm the adequacy of boundaries, setting up equipment, and any activity inside restricted area boundaries.

  (39) Radiographic personnel--Any radiographer, radiographer trainer, or radiographer trainee.

  (40) Residential location--Any area where structures are located in which people lodge or live, and the grounds on which these structures are located including, but not limited to, houses, apartments, condominiums, and garages.

  (41) S-tube--A tube through which the radioactive source travels when inside a radiographic exposure device.

  (42) Shielded position--The location within the radiographic exposure device or source changer where the sealed source is secured and restricted from movement.

  (43) Shielded-room radiography--Industrial radiography conducted in a room shielded so radiation levels at every location on the exterior meet the limitations specified in §289.202(n) of this title or §289.231(o) of this title, as applicable. A shielded room is also known as a bay or bunker.

  (44) Source assembly (pigtail)--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 ball stop used to secure the source in the shielded position.

  (45) Source changer--A device designed and used to replace sealed sources in radiographic exposure devices, including those used to transport and store sealed sources.

  (46) Storage area--Any location, facility, or vehicle that is used to store and secure a radiation machine, radiographic exposure device, a storage container, or a sealed source when it is not used for radiographic operations. Storage areas are locked or have a physical barrier to prevent accidental exposure, tampering, or unauthorized removal of the machine, device, container, or source.

  (47) Storage container--A device in which the sealed source is secured and stored.

  (48) Storage facility--A structure designed to house one or more sources of radiation to provide security and shielding at a permanent storage site. A storage facility is also known as a vault.

  (49) Temporary job site--Any location where industrial radiography is performed other than the specific use location(s) listed on a license or certificate of registration. If use of sources of radiation is authorized at a temporary job site, storage incident to that use is also authorized.

  (50) Trainee status card--The document issued by the agency following completion of the requirements of subsection (e)(1)(A) of this section.

  (51) Transport container--A package that is designed to provide radiation safety and security when sealed sources are transported and meets all applicable requirements of the United States Department of Transportation (DOT).

  (52) Underwater radiography--Industrial radiography performed when the radiographic exposure device and/or related equipment are beneath the surface of the water.

(d) Exemptions.

  (1) Uses of certified and certifiable cabinet x-ray systems are exempt from the requirements of this section except for the requirements of subsections (a), (b)(3), (c), and (t)(8) of this section.

  (2) Industrial uses of hand-held light intensified imaging devices are exempt from the requirements in this section if the exposure rate 18 inches from the source of radiation to any individual does not exceed 2 millirem per hour (mrem/hr) (0.02 millisievert per hour (mSv/hr)). Devices with exposure rates that exceed the 2 mrem/hr (0.02 mSv/hr) level shall meet the applicable requirements of this section and §289.252 of this title or §289.226 of this title, as applicable. This exemption will apply only to those radiation machines that do not allow a person or body part to be exposed to the radiation beam.

  (3) Radiation machines determined by the agency to constitute a minimal threat to human health and safety in accordance with §289.231(ll)(3) of this title, are exempt from the requirements in this section except for the requirements of paragraph (1) of this subsection.

  (4) Facilities that utilize radiation machines for industrial radiography only at permanent radiographic installations are exempt from the requirements of this section except for the requirements of subsections (a), (b)(1), (b)(3) - (5), (c), (e)(1), (j), (n), (t)(1), and (t)(7).

(e) Requirements for qualifications of radiographic personnel.
