Code of Massachusetts Regulations › 105 CMR - DEPARTMENT OF PUBLIC HEALTH › Title 105 CMR 120.000 - The Control of Radiation › REPORTS › Section 120.315 - Performance Requirements for Industrial Radiography Equipment

Current through Register 1525, July 5, 2024
(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.
