Radiation Safety
X-ray machines are used on campus for research and diagnosis.
An X-ray machine produces a beam of ionizing radiation when operating. These machines present no hazard when the power is off. All X-ray machines have a light that indicates when the X-ray is ON as shown below. Ask an operator for direction if questions arise.
Analytical X-ray machines used for research are surrounded by an enclosure (like the one shown below) to prevent personnel exposure and unauthorized entry. Areas around enclosed X-ray devices may be accessed safely.
X-ray machines and labs are posted with a sign or label like the one shown at left.
Most X-ray machines have an interlocking device that prevents entry of limbs, fingers, hands, etc. into the primary beam path or causes the beam to be shut off upon entry into its path.
If you must enter an X-ray room and an operator is not present, stay outside of the X-ray enclosure. Do not disturb any settings.
