a) Equipment used
in industrial radiographic operations involving the use of radiographic
exposure devices shall meet the following minimum criteria:
1) Each radiographic exposure device, source
assembly, or sealed source and all associated equipment:
A) Manufactured on or before July 1, 1994,
and used after January 10, 1996, shall meet the requirements specified in
American National Standards Institute (ANSI) N432-1980, "Radiological Safety
for the Design and Construction of Apparatus for Gamma Radiography", published
January 1981, as NBS Handbook 136, exclusive of subsequent amendments or
editions. This publication may be purchased from the American National
Standards Institute, Inc., 25 West 43rd Street, New
York NY 10036; Telephone: (212) 642-4900. However, equipment used in industrial
radiographic operations need not comply with section 8.9.2(c) of the Endurance
Test in ANSI 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; and/or
B)
Manufactured after July 1, 1994, and used after January 10, 1996, shall meet
the requirements specified in ANSI N43.9 -1991, "American National Standard for
Gamma Radiography - Specifications for Design and Testing of Apparatus",
published 1991, exclusive of subsequent amendments or editions.
2) Each radiographic exposure
device shall have attached to it one or more durable, legible, clearly visible
labels bearing the:
A) Chemical symbol and
mass number of the radionuclide in the device;
B) Activity of the sealed source and the date
this activity was last measured;
C)
Model and serial number of the sealed source;
D) Manufacturer of the sealed source;
and
E) Licensee's name, address and
telephone number.
3)
Each radiographic exposure device intended for use as a Type B transport
container shall meet the applicable requirements of 32 Ill. Adm. Code
341.
4) Radiographic exposure
devices, source assemblies, source changers and associated equipment that allow
the source to be moved out of the device for routine operation shall meet the
following additional requirements:
A) The
coupling between the source assembly and the control cable shall be designed in
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 conditions.
B) The device shall automatically secure the
source assembly when it is cranked back into the shielded position within the
device. This securing system shall only be released by means of a deliberate
operation of 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 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, if manufactured on or before July 1, 1994, and used after January 10,
1996, shall have passed a kinking test that closely approximates the kinking
forces likely to be encountered during use and the crushing tests for the
control units specified in ANSI N432-1980, "Radiological Safety for the Design
and Construction of Apparatus for Gamma Radiography", published January 1981,
as NBS Handbook 136, exclusive of subsequent amendments or editions. Guide
tubes manufactured after July 1, 1994, and used after January 10, 1996, shall
have passed a kinking test that closely approximates the kinking forces likely
to be encountered during use and the crushing tests for the control units
specified in ANSI N43.9-1991, "American National Standard for Gamma Radiography
- Specifications for Design and Testing of Apparatus", published 1991,
exclusive of subsequent amendments or editions.
F) Use of a guide tube shall be necessary to
move the source out of the device.
G) An exposure head, endcap or similar device
designed to prevent the source assembly from extending beyond 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, if these parts were manufactured on or
before July 1, 1994, and used after January 10, 1996, shall be able to
withstand the tensile test for control units specified in ANSI N432-1980,
"Radiological Safety for the Design and Construction of Apparatus for Gamma
Radiography", published January 1981, as NBS Handbook 136, exclusive of
subsequent amendments or editions If these parts were manufactured after July
1, 1994, and used after January 10, 1996, the guide tube exposure head
connection shall be able to withstand the tensile test for control units
specified in ANSI N43.9-1991, "American National Standard for Gamma Radiography
- Specifications for Design and Testing of Apparatus", published 1991,
exclusive of subsequent amendments or editions.
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 drive cable to or from a source
assembly.
