Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(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.
