§ 30332. Performance Requirements for Radiographic Exposure Devices, Storage Containers, and Source Changers.
Currentness
(a) All radiographic exposure devices and associated equipment shall comply with the following:
(1) Except as provided in subsection (b), each radiographic exposure device, source assembly or sealed source and all associated equipment shall meet the requirements specified in American National Standard N432-1980 “Radiological Safety for the Design and Construction of Apparatus for Gamma Radiography,” published as NBS Handbook 136, issued January 1981 (ANSI N432) [FN*];
(2) Each radiographic exposure device shall have attached to it a durable, legible, clearly visible label bearing the:
(A) Chemical symbol and mass number of the radionuclide in the device;
(B) Activity and date on which this activity was last measured;
(C) Model number and serial number of the sealed source;
(D) Manufacturer of the sealed source; and
(E) Licensee's name, address and telephone number;
(3) Radiographic exposure devices intended for use as Type B transport containers shall meet the applicable requirements of section 30373;
(4) Modification of radiographic exposure devices, source changers, source assemblies and associated equipment is prohibited, unless the design of any replacement component, including source holder, source assembly, controls or guide tubes would not compromise the safety design features of the system;
(5) For radiographic exposure devices and associated equipment that allow the source to be moved out of the device for routine operation:
(A) The coupling between the source assembly and the control cable shall be designed in such a manner that the source assembly will not become disconnected if cranked outside the guide tube. The coupling shall be such that it cannot be unintentionally disconnected under normal and reasonably foreseeable abnormal conditions;
(B) The device shall automatically secure the source assembly when it is cranked back into the fully shielded position within the device. This securing system may only be released by means of a deliberate operation on the exposure device;
(C) The outlet fittings, lock box, and control cable fittings on each radiographic exposure device shall be equipped with safety plugs or covers which shall be installed during storage and transportation to protect the source assembly from water, mud, sand or other foreign matter;
(D) Each sealed source or source assembly shall have attached to it or engraved in it, a durable, legible, visible label with the words “Danger-- Radioactive.” The label shall not interfere with the safe operation of the exposure device or associated equipment;
(E) The guide tube shall have passed the crushing tests for the control tube as specified in ANSI N432 and a kinking resistance test that closely approximates the kinking forces likely to be encountered during use;
(F) Guide tubes shall be used when moving the source out of the device.
(G) An exposure head or similar device designed to prevent the source assembly from passing out of the end of the guide tube shall be attached to the outermost end of the guide tube during radiographic operations;
(H) The guide tube exposure head connection shall be able to withstand the tensile test for control units specified in ANSI N432; and
(I) Source changers shall provide a system for assuring that the source will not be accidentally withdrawn from the changer when connecting or disconnecting the control cable to or from a source assembly.
(b) Equipment used in radiographic operations need not comply with section 8.9.2(c) of the Endurance Test in ANSI N432, if the prototype equipment has been tested using a torque value representative of the torque that an individual using the industrial radiography equipment can realistically exert on the lever or crankshaft of the control mechanism.
(c) Storage containers and source changers shall not exceed a radiation exposure rate of 200 millirems per hour (mrem/hr) at any exterior surface and 10 mrem/hr at one meter from any exterior surface with the sealed source in the shielded position.
