Collimator means a small radiation shield of lead or other heavy metal which is placed on the end of a 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 Cable (Drive Cable) means the cable that is connected to the source assembly and used to drive the source from and return it to the shielded position. Control Mechanism (Drive Mechanism) means a device that enables the source assembly to be moved from and returned to the shielded position. A drive mechanism is also known as a crank assembly. Control Tube means a protective sheath for guiding the drive cable. The control tube connects the drive mechanism to the radiographic exposure device. Crank-out Device means the cable, protective sheath, and hand crank used to move the sealed source from the shielded to the unshielded position to make an industrial radiographic exposure. Enclosed Radiography means industrial radiography conducted in an enclosed cabinet or room and includes cabinet radiography and shielded room radiography. Exposure Head (Source Stop) 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. Guide Tube means a flexible or rigid tube, such as a "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. Independent Certifying Organization means an independent organization that meets all of the applicable parts of Appendix A of 10 CFR Part 34 for radioactive materials, and/or comparable criteria for x-ray/combination established by CRCPD. Industrial Radiography means the examination of the macroscopic structure of materials by nondestructive methods using sources of radiation derived from radioactive materials or radiation machines. For purposes of 105 CMR 120.300, industrial radiography does not include radiography performed with Lixiscopes or cabinet x-ray systems, nor does it include computed tomography or computer-based digital radiography in which the useful beam of radiation is collimated to detectors. Industrial Radiography -Radiation Machines means the process of performing industrial radiography using radiation producing machines. Industrial Radiography -Radioactive Materials means the process of performing industrial radiography using radioactive materials. Lay-barge Radiography means industrial radiography performed on any water vessel used for laying pipe. Lixiscope means a portable light-intensified imaging device using iodine-125 as a sealed source. Lock-out Survey means a radiation survey performed to determine that a sealed source is in its shielded position. The lock-out survey is performed before moving the radiographic exposure device or source changer to a new location or securing the radiographic exposure device or source changer. Offshore Platform Radiography means industrial radiography conducted from a platform over a body of water. Permanent Radiographic Installation means an installation or structure designed or intended for radiography and in which radiography is regularly performed and meets all the requirements of 105 CMR 120.319 Personnel Monitoring Badge means a whole body individual monitoring device that meets the requirements of 105 CMR 120.323(B). Personal Supervision means supervision provided by a Certified Industrial Radiographer who is physically present at the site where sources of radiation and associated equipment are being used, visually evaluating the Radiographer Trainee and in such proximity that immediate assistance can be given if required. Radiation Machine means any device capable of producing ionizing radiation except those which produce radiation only from radioactive material. Radiation Safety Officer means 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 and/or registrant and who meets the requirements of 105 CMR 120.380 and 120.005. Radiographer means any individual who has successfully completed the training, testing and documentation requirements of 105 CMR 120.320(B), and who performs or personally supervises industrial radiographic operations and who is responsible to the licensee or registrant for assuring compliance with the requirements of 105 CMR 120.000 and all license and/or certificate of registration conditions.
