216 R.I. Code R. 216-RICR-40-20-6.5

Current through October 15, 2024

Section 216-RICR-40-20-6.5 - Additional Requirements - Category A Industrial Radiation Machines

A. Safety Device. A safety device shall be provided on all open-beam configurations which prevents the entry of any portion of an individual's body into the primary X-ray beam path or which causes the beam to be shut off upon entry into its path shall be provided on all open-beam configurations.

1. A registrant may apply to the Agency for an exemption from the requirement of a safety device. Such application shall include:

a. A description of the various safety devices that have been evaluated;

b. The reason each of these devices cannot be used; and

c. A description of the alternative methods that will be employed to minimize the possibility of an accidental exposure, including procedures to assure that operators and others in the area will be informed of the absence of safety devices.

B. Warning Devices. Open-beam configurations shall be provided with a visible indication of:

1. X-ray tube status (ON - OFF) located near the radiation source housing, if the primary beam is controlled in this manner; and/or

2. Shutter status (OPEN - CLOSED) located near each port on the radiation source housing, if the primary beam is controlled in this manner.

C. Shutters. On open-beam configurations each port on the radiation source housing shall be equipped with a shutter that cannot be opened unless a collimator or a coupling has been connected to the port.

D. Surveys

1. Radiation surveys, as required by §1.10.2 of this Subchapter, of industrial radiation machines sufficient to show compliance with §6.4.1 of this Part shall be performed:

a. Upon installation of the equipment, and at least once every twelve (12) months thereafter;

b. Following any change in the initial arrangement, number, or type of local components in the system;

c. Following any maintenance requiring the disassembly or removal of a local component in the system;

d. During the performance of maintenance and alignment procedures if the procedures require the presence of a primary X-ray beam when any local component in the system is disassembled or removed; and

e. Any time a visual inspection of the local components in the system reveals an abnormal condition.

f. Whenever personnel monitoring devices show a significant increase over the previous monitoring period or the readings are approaching the radiation dose limits.

2. Radiation survey measurements shall not be required if a registrant can demonstrate, to the satisfaction of the Agency, compliance with §6.4.1 of this Part in some other manner.

E. Generator Cabinet. Each X-ray generator shall be supplied with a protective cabinet which limits leakage radiation measured at a distance of five (5) cm from its surface such that it is not capable of producing a dose in excess of one half (0.5) mrem (five (5) µSv) in any one (1) hour.
