Radiological Safety Training for Radiation-Producing (X-Ray) Devices

Instructor=s Guide

X-Ray Device Control Office: A team that establishes X-ray device program requirements and standards,

provides X-ray device radiation protection consultation, and serves as the central point of contact for the

management/control of X-ray devices. This function may have a facility-specific name.

X-ray device custodian: A person designated by line management as responsible for specific X-ray

devices. This individual is responsible for designating the operators of specific X-ray devices, arranging

for the operators to attend X-ray safety training, assisting in the development and maintenance of the X-ray

device SOP, familiarizing operators with the X-ray device SOP, maintaining records of operator training

and safety interlock checks, serving as the point of contact for the line organization's X-ray devices, and

coordinating surveys with the X-Ray Device Control Office. An X-ray device custodian may also be an

X-ray device operator.

X-ray device operator: An individual designated in writing by the X-ray-device custodian and qualified

by training and experience to operate a specific X-ray device.

X-ray diffraction: The scattering of X-rays by matter with accompanying variation in intensity in

different directions due to interference effects.

X-ray installation: One or more X-ray systems, the surrounding room or controlled area, and the

installation enclosure.

X-ray power supply: The portion of an X-ray device that generates the accelerating voltage and current

for the X-ray tube.

X-ray source housing: An enclosure directly surrounding an X-ray tube that provides attenuation of the

radiation emitted by the X-ray tube. The X-ray source housing typically has an aperture through which the

useful beam is transmitted.

X-ray system: An assemblage of components for the controlled generation of X-rays.

X-ray tube: An electron tube that is designed for the conversion of electrical energy to X-ray energy.
