A review conducted or provided by the licensee or registrant for its employees on radiation safety aspects of industrial radiography. The review must include, as a minimum, any results of internal inspections, new procedures, or equipment, new or revised regulations, and accidents or errors that have been observed. The review must also provide opportunities for employees to ask safety questions. 002.02 ASSOCIATED EQUIPMENT. Equipment used in conjunction with a radiographic exposure device to make radiographic exposures that drives, guides, or comes in contact with the source. Associated equipment includes, but is not limited to the guide tube, control or drive cable, removable stop, and the “J” tube and collimator when used as an exposure head. 002.03 CAMERA. Has the same meaning as radiographic exposure device. 002.04 CERTIFYING ENTITY. An independent certifying organization meeting the requirements in Appendix A of 180 NAC 5 or a state regulatory program meeting the requirements in Appendix A, Parts II and III of 180 NAC 5. 002.05 COLLIMATOR. 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. 002.06 CONTROL CABLE. A cable connected to the source assembly and used to drive the source to and from the exposure location. A control cable is also known as a drive cable. 002.07 CONTROL DRIVE MECHANISM. A device that enables the source assembly to be moved into and out of the exposure device. 002.08 CONTROL TUBE. A protective sheath for guiding the control cable. The control tube connects the control drive mechanism to the radiographic exposure device. 002.09 DRIVE CABLE. Has the same meaning as control cable. 002.10 EXPOSURE HEAD. Device that locates the gamma radiography sealed source in the selected working position. An exposure head is also known as a source stop. 002.11 FIELD STATION. A facility where sources of radiation may be stored or used and from which equipment is dispatched. 002.12 GUIDE TUBE. A flexible or rigid tube or “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. A guide tube is also known as a projection sheath. 002.13 HANDS-ON EXPERIENCE. Experience in all of those areas considered to be directly involved in the radiography process that includes, but is not limited to 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, as applicable. 002.14 INDEPENDENT CERTIFYING ORGANIZATION. An organization that meets all the criteria of Appendix A to 180 NAC 5. 002.15 INDUSTRIAL RADIOGRAPHY. An examination of the structure of materials by nondestructive methods using sources of ionizing radiation to produce radiographic images. Also known as radiography. 002.16 PERMANENT RADIOGRAPHIC INSTALLATION. An enclosed shielded room, cell, or vault, not located at a temporary jobsite, where radiography is performed. 002.17 PIGTAIL. Has the same meaning as source assembly. 002.18 PRACTICAL EXAMINATION. A demonstration through application of the safety rules and principles in industrial radiography including use of all procedures and equipment to be used by radiographic personnel. 002.19 PROJECTOR. Has the same meaning as radiographic exposure device. 002.20 RADIATION SAFETY OFFICER FOR INDUSTRIAL RADIOGRAPHY. An individual with the responsibility for the overall radiation safety protection program on behalf of the licensee or registrant and who meets the requirements of 180 NAC 5-015. 002.21 RADIOGRAPHER. Any individual who performs or who, in attendance at the site where the 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 the Department’s regulations and the conditions of the license or registration. 002.22 RADIOGRAPHER’S ASSISTANT. Any individual who under the direct supervision of a radiographer, uses radiographic exposure devices, sources of radiation, related handling tools, or radiation survey instruments in industrial radiography. 002.23 RADIOGRAPHER CERTIFICATION. Written approval received from a certifying entity stating that an individual has satisfactorily met the radiation safety, testing, and experience criteria in 180 NAC 15-016. 002.24 RADIOGRAPHIC EXPOSURE DEVICE. Any instrument containing a sealed source fastened or contained therein, where 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. A radiographic exposure device is also known as a camera or projector. 002.25 RADIOGRAPHIC OPERATIONS. All activities performed with a radiographic exposure device, or with a radiation machine. Activities include using, transporting, except by common or contract carriers, or storing a temporary job site, performing surveys to confirm the adequacy of boundaries, setting up equipment, and any activity inside restricted area boundaries. Transporting a radiation machine is not considered a radiographic operation. 002.26 RADIOGRAPHY. See Industrial radiography. 002.27 S-TUBE. A tube through which the radioactive source travels when inside a radiographic exposure device. 002.28 SEALED SOURCE. Has the same meaning as 180 NAC 1-002. 002.29 SHIELDED POSITION. A location within the radiographic exposure device, source changer or storage container that, by manufacturer's design, is the proper location for storage of the sealed source. 002.30 SOURCE ASSEMBLY. Consists of the sealed source and a connector that attaches the source to the control cable. The source assembly may include a ballstop to secure the source in the shielded position. Also known as a pigtail. 002.31 SOURCE CHANGER. A device designed and used for replacement of sealed sources in radiographic exposure devices. A source changer may also be used for transporting and storing sealed sources. 002.32 STORAGE AREA. Any location, facility, or vehicle that is used to store and secure a radiographic exposure device, a radiation machine, sealed source, or a storage container, 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 device, machine, or container. 002.33 STORAGE CONTAINER. A device in which sealed sources or radiation machines are secured or stored. 002.34 TEMPORARY JOB SITE. A location where radiographic operations are performed and where sources of radiation may be stored other than the location(s) of use authorized on the license or registration. 002.35 UNDERWATER RADIOGRAPHY. Radiographic operations performed when the radiographic exposure device or radiation machine or related equipment, or both, are beneath the surface of the water.
