   Operating procedures—Step-by-step instructions necessary to accomplish the analysis.

   Primary beam—Radiation which passes through an aperture of the source housing by a direct path from the X-ray tube or a radioactive source located in the radiation source housing.

   X-ray calibration systems—Radiation-producing machines and equipment used to calibrate radiation detection or measuring devices.

   X-ray gauging equipment—A machine utilizing X-rays to detect, measure, gauge or control thickness, density, level or interface location.
