Section 6 CCR 1007-1-8.6 - Additional Requirements for Closed-Beam RGDs

In addition to the requirements of 8.3, 8.4, and 8.5, the following applies to all closed-beam x-ray RGDs:

8.6.1 System Enclosure.

The radiation source, sample or object, detector, and analyzing crystal (if used) shall be enclosed in a chamber or coupled chambers that cannot be entered by any part of the body during normal operation.

8.6.2 Interlocks.

All doors and panels accessing the RGDs shall be interlocked. The interlocks required by this section shall be of a fail-safe design.

8.6.3 Interlock Functions.

The system enclosure, sample chamber, etc. closure shall be interlocked with the x-ray tube high voltage supply and/or a shutter in the primary beam so that no x-ray beam can enter the sample or object chamber while it is open unless the interlock has been conspicuously and deliberately defeated. The interlock required by this section shall be of fail-safe design or adequate administrative controls shall be exercised to ensure operations will not continue without a proper functioning interlock.

8.6.4 Radiation Emission Limit.

The radiation emission for all closed beam RGDs shall not exceed a dose rate of 0.5 mrem (0.005 mSv) in one hour at five centimeters outside any accessible surface.

8.6.5 Security Screening Units.

During operation and generation of radiation, security screening units shall require operator presence at the control panel and shall permit surveillance of openings and doors.

A. During an exposure or preset succession of exposures of one-half second or longer, means shall be provided to terminate the exposure or preset succession of exposures at any time.
B. During an exposure or preset succession of exposures of less than one-half second, means shall be provided to permit completion of the exposure in progress, but shall allow the operator to prevent or terminate additional exposures.
