Current through all regulations passed and filed through March 18, 2024
Equipment used in industrial radiographic operations must meet
the following minimum criteria:
(A)
(1) Each radiographic exposure device, source
assembly or sealed source, and all associated equipment must meet the
requirements specified in american national standards 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 may be purchased from the "American National Standards Institute,
Inc., 25 West 43rd Street, New York, New York 10036, telephone (212)
642-4900."
(2) Engineering analysis
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 director may find this an acceptable alternative
to actual testing of the component pursuant to the above referenced
standard.
(B) In
addition to the requirements specified in paragraph (A) of this rule, 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 must meet the
applicable requirements of Chapter 3701:1-50 of the Administrative
Code.
(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 paragraphs (A) and (B) of this rule, 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.
(1) The coupling between the source assembly
and the control cable must 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 must 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.
(3) The outlet fittings, lock box, and drive
cable fittings on each radiographic exposure device must 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.
(4)
(a) Each sealed source or source assembly
must have attached to it or engraved on it, a
durable, legible, visible label with the words: "DANGER-RADIOACTIVE."
(b) The label may not interfere with the safe
operation of the exposure device or associated equipment.
(5) The guide tube must 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 that are likely to be
encountered during use.
(6) Guide
tubes must be used when moving the source out of the device.
(7) An exposure head or similar device
designed to prevent the source assembly from passing out of the end of the
guide tube must be attached to the outermost end of the guide tube during
industrial radiography operations.
(8) The guide tube exposure head connection
must be able to withstand the tensile test for control units specified in
american national standards 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 may be purchased from the
"American National Standards Institute, Inc., 25 West 43rd Street, New York, New York 10036,
telephone (212) 642-4900."
(9)
Source changers must 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, must comply with the
requirements of this rule.
(E)
Notwithstanding paragraph (A)(1) of this rule, equipment used in industrial
radiographic operations need not comply with the requirements of section
8.9.2(c) of the endurance test as specified in American national standards
institute, N432-1980 "Radiological Safety for the Design and Construction of
Apparatus for Gamma Radiography," (published as NBS handbook 136, issued
January 1981), 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. 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."
