Louisiana Administrative Code › Title 33 - ENVIRONMENTAL QUALITY › Part XV - Radiation Protection › Chapter 5 - Radiation Safety Requirements for Industrial Radiographic Operations › Subchapter A - Equipment Control › Section XV-550 - Performance Requirements for Radiography Equipment

Current through Register Vol. 50, No. 6, June 20, 2024
A. Equipment serviced, maintained, or
				  repaired by a licensee or registrant or used in industrial radiographic
				  operations shall meet the following minimum criteria:
1. each radiographic exposure device, source
				  assembly, or sealed source, and all associated equipment shall meet the
				  requirements specified in American National Standard Institute (ANSI) 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:

.
				  Engineering analyses may be submitted by an applicant or licensee to
				  demonstrate the applicability of previously performed testing on similar
				  individual radiography equipment components. Upon review, the department may
				  find this an acceptable alternative to actual testing of the component in
				  accordance with the referenced standard;
2. in addition to the requirements specified
				  in Paragraph A.1 of this Section, the following requirements apply to
				  radiographic exposure devices, source changers, source assemblies, associated
				  equipment, and sealed sources:
a. the
				  licensee shall ensure that each radiographic exposure device has attached to
				  it, a durable, legible, clearly visible label bearing the following:
i. chemical symbol and mass number of the
				  radionuclide in the device;
ii.
				  activity and the date on which this activity was last measured;
iii. model number (or product code) and
				  serial number of the sealed source;
iv. manufacturers identity of the sealed
				  source; and
v. the licensee's name,
				  address, and telephone number;
b. radiographic exposure devices intended for
				  use as Type B transport containers shall meet the applicable requirements of
				  LAC 33:XV.Chapter 15; and
c.
				  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 design safety features of the
				  system;
3. in addition
				  to the requirements specified in Paragraphs A.1 and 2 of this Section, the
				  following requirements apply to radiographic exposure devices, source
				  assemblies, and associated equipment that allow the source to be moved out of
				  the device for radiographic operations or to source changers:
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 extended 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 retracted 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 drive
				  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 on 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 must have passed the crushing tests for the control tube as specified in
				  ANSI N432 and shall be able to withstand a crushing test that closely
				  approximates the crushing forces that are likely to be encountered during use,
				  and be able to withstand 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 industrial radiographic operations;
h. the guide tube exposure head connection
				  shall be able to withstand the tensile test for control units specified in ANSI
				  N432-1980;
i. 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;
j.
				  malfunction of any exposure device or associated equipment shall be reported to
				  the Office of Environmental Compliance by telephone at (225) 765-0160 in
				  accordance with the requirements of LAC 33:XV.341; and
k. notwithstanding Paragraphs A.1, 4, and 5
				  of this Section, equipment used in industrial radiographic operations need not
				  comply with Section 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;
4. all
				  newly manufactured radiographic exposure devices and associated equipment
				  acquired by licensees or registrants after the effective date of these
				  regulations shall comply with the requirements of LAC 33:XV.550; and
5. all radiographic exposure devices and
				  associated equipment in use after January 10, 1996, shall comply with the
				  requirements of LAC 33:XV.550.
