Ariz. Admin. Code § 9-7-802
"Analytical x-ray equipment" means devices or machines used for x-ray diffraction or x-ray induced fluorescence analysis.
"Analytical x-ray system" means a group of components utilizing x-rays to determine the elemental composition or to examine the microstructure of materials.
"Enclosed beam x-ray system" means an analytical x-ray system constructed in such a way that access to the interior of the enclosure housing the x-ray source is precluded during operation except through bypassing of interlocks or other safety devices to perform maintenance or servicing.
"Fail-safe characteristic" means a design feature which causes beam port shutters to close, or otherwise prevents emergence of the primary beam, upon the failure of a safety or warning device.
"Local component" means part of an analytical x-ray system and includes each area that is struck by x-rays such as radiation source housings, port and shutter assemblies, collimators, sample holders, cameras, goniometers detectors and shielding, but does not include power sup-plies, transformers, amplifiers, readout devices, and control panels.
"Normal operating procedures" means instructions or procedures including but not limited to, sample insertion and manipulation, equipment alignment, routine maintenance by the registrant, and data recording procedures which are related to radiation safety.
"Open beam x-ray system" means an analytical x-ray system which permits an individual to place some body part in the primary beam path during normal operation.
"Primary beam" means radiation which passes through an aperture of the source housing on a direct path from the x-ray tube.
