Universal Citation: NH Admin Rules He-P 4034.06

Current through Register No. 40, October 3, 2024

Equipment used in industrial radiographic operations shall meet the following minimum criteria:

(a) Each radiographic exposure device, source assembly or sealed source, and all associated equipment shall meet the requirements specified in American National Standard Institute, N432-1980 "Radiological Safety for the Design and Construction of Apparatus for Gamma Radiography," (published as NBS Handbook 136, issued January 1981) . This publication has been approved for incorporation by reference by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR Part 51. This publication may be purchased from the American National Standards Institute, Inc., 25 West 43rd Street, New York, New York 10036; Telephone: (212) 642-4900. Copies of the document are available for inspection at the Nuclear Regulatory Commission Library, 11545 Rockville Pike, Rockville, Maryland 20852. A copy of the document is also on file at the National Archives and Records Administration (NARA) . For information on the availability of this material at NARA, call 202-741-6030, or go to: http://www.archives.gov/federal_register/code_of_federal_regulations/ibr_locations.html.

(b) In addition to the requirements specified in He-P 4034.06(a), the following requirements apply to radiographic exposure devices, source changers, source assemblies and sealed sources:

(1) The licensee shall ensure that each radiographic exposure device has 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 the date on which this activity was last measured;

c. Model or product code and serial number of the sealed source;

d. Manufacturer's identity of the sealed source; and

e. Licensee's name, address, and telephone number;

(2) Radiographic exposure devices intended for use as Type B transport containers shall meet the applicable requirements of He-P 4037; and

(3) Modification of radiographic exposure devices, source changers, and 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 design safety features of the system;

(c) In addition to the requirements specified in He-P 4034.06(a) and (b) of this section, the following requirements shall apply to radiographic exposure devices, source assemblies, source changers, and associated equipment that allow the source to be moved out of the device for radiographic operations:

(1) 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 must be such that it cannot be unintentionally disconnected under normal and reasonably foreseeable abnormal conditions;

(2) The device shall automatically secure the source assembly when it is cranked back into the fully shielded position within the device;

(3) This securing system required in He-P 4034.06(c) (2) shall only be released by means of a deliberate operation on the exposure device;

(4) The outlet fittings, lock box, and drive cable fittings on each radiographic exposure device shall be equipped with safety plugs or covers which must be installed during storage and transportation to protect the source assembly from water, mud, sand or other foreign matter;

(5) Each sealed source or source assembly shall have attached to it or engraved on it, a durable, legible, visible label with the words: "DANGER - RADIOACTIVE";

(6) The label required in He-P 4034.05(c) (5) shall not interfere with the safe operation of the exposure device or associated equipment;

(7) The guide tube shall:
a. Be able to withstand a crushing test that closely approximates the crushing forces that are likely to be encountered during use; and

b. Be able to withstand a kinking resistance test that closely approximates the kinking forces that are likely to be encountered during use;

(8) Guide tubes shall be used when moving the source out of the device;

(9) 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 industrial radiography operations;

(10) The guide tube exposure head connection shall be able to withstand the tensile test for control units specified in ANSI N432-1980; and

(11) Source changers shall provide a system for ensuring that the source will not be accidentally withdrawn from the changer when connecting or disconnecting the drive cable to or from a source assembly.

(d) All radiographic exposure devices and associated equipment in use after January 10, 1996, shall comply with the requirements of He-P 4034.06; and

(e) Notwithstanding He-P 4034.06(a), equipment used in industrial radiographic operations shall not be required to comply with "[SECTION]sect; 8.9.2(c) of the Endurance Test in American National Standards Institute N432-1980," if the prototype equipment has been tested using a torque value representative of the torque that an individual using the radiography equipment can realistically exert on the lever or crankshaft of the drive mechanism.
