Section 0400-20-08-.03 - DEFINITIONS(1) "Annual refresher safety training" means a review conducted or provided by the licensee or registrant for its 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 and receive answers to their safety questions.(2) "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.(3) "Cabinet radiography" means industrial radiography using radiation machines in an enclosed interlocked cabinet in which: .(a) The radiation machine will not operate unless all openings are closed with interlocks activated.(b) The cabinet is so shielded that every location on the exterior meets the conditions for an unrestricted area as defined in Chapter 0400-20-05, and(c) The cabinet is so constructed or arranged as to exclude the entrance of any part of the body of an individual during irradiation.(d) Baggage entrance and exit openings of airport baggage systems need not be interlocked. All other openings in these systems shall be interlocked. The operator shall be present during operation to ensure no individual enters the device through the baggage entrance or exit opening(s).(4) "Certifying entity" means an independent certifying organization meeting the requirements in Appendix A to 10 CFR 34 or an Agreement State meeting the requirements in Appendix A to 10 CFR 34 (see Schedule RHS 8-35, Rule 0400-20-08-.16) .(5) "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.(6) "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.(7) "Control drive mechanism" means a device that enables the source assembly to be moved to and from the exposure device.(8) "Control tube" means a protective sheath for guiding the control cable. The control tube connects the control drive mechanism to the radiographic exposure device.(9) "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".)(10) "Field station" means a facility where licensed or registered material may be stored or used and from which equipment is dispatched.(11) "Guide tube" (or "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.(12) "Hands-on experience" means experience in all of those areas considered to be directly involved in the radiography process.(13) "Independent certifying organization" means an independent organization that meets all of the criteria of appendix A to 10 CFR 34 (see Rule 0400-20-08-.16) .(14) "Industrial Radiography" means an examination of the structure of materials by the nondestructive method of utilizing ionizing radiation to make radiographic images.(15) "Permanent radiographic installation" means an enclosed shielded room, cell or vault, not located at a temporary job-site, in which radiography is performed. .(16) "Personal supervision" means supervision with the radiographer:(a) Physically present at the site where sources of radiation and associated equipment are being used.(b) Observing the radiographer's assistant's performance; and(c) In such proximity that immediate assistance can be given if required.(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) "Radiographer" means any individual who performs or who, in attendance at the site where the radiographic exposure devices 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 Division's regulations and the conditions of the license or registration.(19) "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.(20) "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.(21) "Radiographic exposure device" (also called a 'camera' or a 'projector') means: (a) Any instrument having a sealed source 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; or(b) Any apparatus that may produce, when the associated controls are operated, one or more forms of radiation used for making a radiographic exposure.(22) "Radiographic operations" means all activities associated with the presence of sources of radiation 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.(23) "S-tube" means a tube through which the radioactive source travels when inside a radiographic exposure device.(24) "Shielded position" means the location within the radiographic exposure device or source changer where the sealed source is secured and restricted from movement.(25) "Shielded room x-ray radiography" means industrial radiography using radiation machines that is conducted in an enclosed room.(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 industrial radiography is performed and where licensed or registered material may be stored other than the location(s) of use authorized on the specific license or registration.Tenn.
