(A)
Conformance with ANSI
Standards. Equipment used in industrial radiographic operations
shall meet the following minimum criteria:
(1) Each radiographic exposure device, source
assembly, sealed source, and associated equipment shall meet the criteria set
forth by 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 may be purchased from the
American National Standards Institute, Inc., 25 West 43rd Street, New York, New
York 10036; Telephone: (212) 642-4900.
(2) Radiation machines manufactured after
January 10, 1992 used in industrial radiographic operations shall be certified
at the time of manufacture to meet the criteria set forth by ANSI N537- 1976,
except accelerators used in industrial radiography.
(3) All radiographic exposure devices and
associated equipment in use after January 10, 1996, must comply with the
requirements of 105 CMR 120.315.
(4) In lieu of 105 CMR
120.315(A)(1), equipment used in industrial radiographic operations need not
comply with § 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.
(5) Engineering analysis may be submitted by
a licensee to demonstrate the applicability of previously performed testing on
similar individual radiography equipment components. Upon review, the agency
may find this an acceptable alternative to actual testing of the component in
accordance with 105 CMR 120.315(A)(1).
(6) In addition to the requirements specified
in 105 CMR 120.315(A)(1), the following requirements apply to radiographic
exposure devices, source changers, source assemblies, sealed sources and
associated equipment.
(a) The licensee shall
ensure that each radiographic exposure device has attached to it a durable,
legible, clearly visible label bearing the:
1.
Chemical symbol and mass number of the radionuclide in the device;
2. Activity and the date on which this
activity was last measured;
3.
Model or product code and serial number of the sealed source;
4. Name of the manufacturer of the sealed
source; and,
5. Licensee's name,
address, and telephone number.
(b) Radiographic exposure devices intended
for use as Type B packages must meet the applicable transportation requirements
of 10 CFR part 71.
(c) Opening,
repair or modification of radiographic exposure devices, source changers, and
source assemblies and associated equipment is prohibited, unless approved by
the Agency, the U.S. Nuclear Regulatory Commission (NRC) or Agreement
State.
(7) Modification
of any exposure devices 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.
(B)
Labeling Storage, and Transportation
(1) The licensee may not use a radiographic
exposure device source changer or a container to store radioactive material
unless the radiographic exposure device source changer or the storage container
has securely attached to it a durable, legible, and clearly visible label
bearing the standard trefoil radiation caution symbol conventional colors,
i.e., magenta, purple or black on a yellow background, having
a minimum diameter of 25 mm, and the wording:
" CAUTION. RADIOACTIVE MATERIAL. NOTIFY CIVIL AUTHORITIES (OR
NAME OF COMPANY)" or "DANGER. RADIOACTIVE MATERIAL. NOTIFY CIVIL AUTHORITIES
(OR NAME OF COMPANY)."
(2)
The licensee may not transport radioactive material unless the material is
packaged, and the package is labeled, marked, and accompanied with appropriate
shipping papers in accordance with
105 CMR
120.770
(3) Radiographic exposure devices, source
changers, storage containers, and radiation machines, must be physically
secured to prevent tampering or removal by unauthorized personnel. The licensee
shall store radioactive material in a manner that will minimize danger from
explosion or fire.
(4) The licensee
shall lock and physically secure the transport package containing radioactive
material in the transporting vehicle to prevent accidental loss, tampering, or
unauthorized removal.
(5) The
licensee's or registrant's name and city or town where the main business office
is located shall be prominently displayed with a durable, clearly visible
label(s) on both sides of all vehicles used to transport radioactive material
or radiation machines for temporary job site use.
(C)
Performance
Requirements. In addition to the requirements specified in 105 CMR
120.315(A) and (B), 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 routine operations or to source
changers:
