Part He-P 4034 - RADIATION SAFETY REQUIREMENTS FOR INDUSTRIAL RADIOGRAPHIC OPERATIONS
Section He-P 4034.03 - Definitions

(a) "ALARA" (acronym for "as low as is reasonably achievable") means making every reasonable effort to maintain exposures to radiation as far below the dose limits specified in He-P 4020 as is practical consistent with the purpose for which the licensed activity is undertaken, taking into account the state of technology, the economics of improvements in relation to state of technology, the economics of improvements in relation to benefits to the public health and safety, and other societal and socioeconomic considerations, and in relation to utilization of nuclear energy and licensed materials in the public interest;

(b) "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;

(c) "Associated equipment" means equipment that is used in conjunction with a radiographic exposure device to make radiographic exposures that drives, guides, or otherwise 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);

(d) "Cabinet radiography" means industrial radiography conducted in an enclosure or cabinet so shielded that every location on the exterior meets the dose limits for the individual member of the public as specified in He-P 4020;

(e) "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 and is intended to contain at least that portion of a material being irradiated, provide radiation attenuation, and exclude personnel from its interior during generation of radiation. The term includes "cabinet" and x-ray systems designed primarily for the inspection of carry-on baggage at airline, railroad, and bus terminals and in similar facilities. An x-ray tube used within a shielded part of a building, or x-ray equipment that might temporarily or occasionally incorporate portable shielding, is not a cabinet x-ray system;

(f) "Certifiable cabinet x-ray system" means an existing uncertified x-ray system that has been modified to meet the certification requirements specified in 21 CFR 1010.2;

(g) "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 pursuant to the provisions of 21 CFR 1020.40;

(h) "Certifying entity" means an independent certifying organization meeting the requirements in He-P 4034 Appendix A, Parts II and III, or the equivalent requirements of an Agreement State or in Nuclear Regulatory Commission 10 CFR 34 appendix A;

(i) "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;

(j) "Control cable" means the cable that is connected to the source assembly and used to drive the source to and from the exposure location. The term includes "drive cable";

(k) "Control drive mechanism"means a device that enables the source assembly to be moved into and out of the exposure device;

(l) "Control tube" means a protective sheath which connects the control drive mechanism to the radiographic exposure device for guiding the control cable;

(m) "Exposure head" means a device that locates the gamma radiography sealed source in the selected working position. The term includes "source stop";

(n) "Field station" means a facility from which sources of radiation may be stored or used and from which equipment is dispatched;

(o) "Guide tube" means a flexible or rigid, "J" tube, for guiding the source assembly and the attached control cable from the exposure device to the exposure head which may also include the connections necessary for attachment to the exposure device and to the exposure head. The term includes "projection sheath";

(p) "Hands-on experience" means experience in all of those areas considered to be directly involved in the radiography process, and includes taking radiographs, calibration of survey instruments, operational and performance testing of survey instruments and devices, film development, posting of radiation areas, transportation of radiography equipment, posting of records, and radiation area surveillance;

(q) "Independent certifying organization" means an independent organization that meets all of the criteria of He-P 4034 Appendix A;

(r) "Industrial radiography" means an examination of the structure of materials by nondestructive methods, utilizing ionizing radiation to make radiographic images;

(s) "Lay-barge radiography" means industrial radiography performed on any water vessel used for laying pipe;

(t) "Offshore platform radiography" means industrial radiography conducted from a platform over a body of water;

(u) "Permanent radiographic installation" means an enclosed shielded room, cell, or vault, not located at a temporary job site, in which radiography is performed;

(v) "Practical examination" means a demonstration through application of the safety rules and principles in industrial radiography including use of all appropriate procedures and equipment to be used by radiographic personnel;

(w) "Radiation safety officer for industrial radiography" means an individual with the responsibility for the overall radiation safety program on behalf of the licensee or registrant and who meets the requirements of He-P 4034.16;

(x) "Radiographer" means any individual who performs or who, in attendance at the site where the sealed sources or sources of radiation are being used, personally supervises industrial radiographic operations and who is responsible to the licensee or registrant for assuring compliance with the requirements of DHHS/RHS rules and the conditions of the license or the registration;

(y) "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;

(z) "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;

(aa) "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. The term includes "camera" or "projector";

(ab) "Radiographic operations" means all activities associated with the presence of radioactive source in a radiographic exposure device or with a radiation machine to include use, transport (except when being transported by a common or contract transport) performing surveys to confirm the adequacy of boundaries, setting up equipment, and any activity inside restricted area boundaries;

(ac) "S-tube" means a tube through which the radioactive source travels when inside a radiographic exposure device;

(ad) "Shielded position" means the location within the radiographic exposure device or source changer where the sealed source is secured and restricted from movement;

(ae) "Source assembly" means an assembly that consists of the sealed source and a connector that attaches the source to the control cable and may include a stop ball used to secure the source in the shielded position;

(af) "Source changer" means a device designed and used for replacement of sealed sources in radiographic exposure devices which may also be used for transporting and storing sealed sources;

(ag) "Storage area" means any location, facility, or vehicle which is used to store or to secure a radiographic exposure device, a storage container, a sealed source, or a radiation machine 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, source, or radiation machine;

(ah) "Storage container" means a container in which sealed sources are secured and stored;

(ai) "Temporary jobsite" means a location where radiographic operations are conducted and where licensed material may be stored other than those location(s) of use authorized on the license; and

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