Section 144-220-E-A-3 - Definitions

As used in this Part, the following definitions apply:

Annual refresher safety training means a review conducted or provided by the licensee for it 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, accidents or errors that have been observed, and should also provide opportunities for employees to ask safety questions.

Associated equipment means 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 x-ray system means an x-ray system with the x-ray tube installed in an enclosure independent of existing architectural structures except the floor on which it may be placed. 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. The cabinet x-ray system is intended to:

(a) Contain at least that portion of a material being irradiated;
(b) Provide radiation attenuation; and
(c) Exclude personnel from its interior during generation of radiation.

Certifiable cabinet x-ray system means an existing uncertified x-ray system that has been modified to meet the certification requirements specified in 21 Code of Federal Regulations (CFR).

Certification identification (ID) card means the document issued by the Agency to individuals who have completed the requirements stated in E.16.B.

Certified cabinet x-ray system means an x-ray system that has been certified in accordance with 21 CFR 1010.2 as being manufactured and assembled on or after April 10, 1975, according to the provisions of 21 CFR 1020.40.

Certifying entity means an independent certifying organization whose certification program has been reviewed and found to meet the requirements in Appendix A of 10 CFR Part 34 for radioactive materials and/or equivalent requirements for x-ray, or an Agreement State meeting the same requirements.

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.

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 to return it to the shielded position.

Control drive mechanism - see crank out device.

Control tube means a protective sheath for guiding the control cable. The control tube connects the control drive mechanism to the radiographic exposure device.

Crank-out device means the drive cable, control tube, and drive mechanism used to move the sealed source to and from the shielded position to make an industrial radiographic exposure.

Enclosed radiography means industrial radiography conducted in an enclosed cabinet or room. Enclosed radiography includes shielded-room radiography.

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).

Fluoroscopic imaging assembly means a subsystem in which x-ray photons produce a fluoroscopic image. It includes the image receptors such as the image intensifier and spot-film device, electrical interlocks, if any, and structural material providing linkage between the image receptor and source assembly.

Guide tube (Projection sheath) means a flexible or rigid tube (e.g. 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 experiencemean experience in all of those areas considered to be directly involved in the radiography process. This is also known as on-the-job training. 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.

Independent certifying organization means an independent organization that meets all of the criteria of Appendix A of 10 CFR Part 34 for radioactive materials, or comparable standards for x-ray.

Industrial radiography means an examination of the structure of materials by nondestructive methods, utilizing ionizing radiation to produce radiographic images.

Lay-barge radiography means industrial radiography performed on any water vessel used for laying pipe.

Lock-out survey means 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.

Offshore platform radiography means industrial radiography conducted from a platform over a body of water.

Permanent radiographic installation means an enclosed shielded room, cell, or vault, not located at a temporary jobsite, in which radiography is performed and meets the criteria of E.12.

Personal supervision means supervision in which the radiographer trainer is physically present at the site where sources of radiation, associated equipment, and survey meters are being used, watching the performance of the radiographer assistant and in such proximity that immediate assistance can be given if required.

Pipeliner means a directional beam radiographic exposure device.

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.

Radiation safety officer (RSO) for industrial radiography means an individual with responsibility for the overall radiation safety program on behalf of the licensee or registrant and who meets the requirements of E.15.A of this section.

Radiographer means any individual who performs or who, in attendance at the site where a sealed source or sources are being used, personally supervises industrial radiographic operations 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.

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.

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.

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.

Radiographic operations means 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.

Radiographic personnel means any radiographer or radiographer assistant.

Residential location means any area where structures in which people lodge or live are located, and the grounds on which such structures are located including, but not limited to, houses, apartments, condominiums, and garages.

S-tube means a tube through which the radioactive source travels when inside a radiographic exposure device.

Shielded position means the location within the radiographic exposure device or source changer where the sealed source is secured and restricted from movement.

Shielded-room radiography means industrial radiography conducted in a room so shielded that radiation levels at every location on the exterior meet the limitations specified in Part D of this rule. A shielded room is also known as a bay or bunker.

Source assembly (pigtail) 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.

Source changer means a device designed and used for replacement of the sealed sources in radiographic exposure devices, including those also used for transporting and storage of sealed sources.

Underwater radiography means industrial radiography performed when the radiographic exposure device and/or related equipment are beneath the surface of the water.
