Enclosed beam RGD definition
Enclosed beam RGD means an RGD with all possible x-ray beam paths contained in a chamber, coupled chambers, or other beam-path-confinement devices, to prevent any part of the body from intercepting the beam during normal operations. Normal access to the primary beam path, such as a sample chamber door, shall be interlocked with the high voltage of the x-ray tube or the shutter for the beam to be considered "enclosed." An open-beam device placed in an interlocked enclosure is considered an "enclosed beam" unless there are provisions for routine bypassing of the interlocks.
Enclosed beam RGD means an RGD with all possible x-ray beam paths fully contained in a
