An operating log should be maintained by the x-ray technician. All machine operations, installation designs, etc. All personnel shall wear the required dosimeter assigned to them by the Radiation Safety Office. Any employee required to be in the room during operation of the x-ray unit shall wear a protective lead apron or stand behind a protective barrier. Irradiators shall be used in rooms such that exposure rates outside the shield room do not exceed 5 mR in any one hour, all doors with access to the room are equipped with interlocks and a visible warning light indicates when the machine is on.
Serious damage can result to eyes and skin even if the exposure time is very short.
Extreme caution must be exercised in the use of x-ray diffraction machines. The authorized PI is responsible for assuring that x-ray diffraction machines are kept in good condition, that safety systems are functioning, and that the equipment meets specifications. When required, dosimetry shall be worn whenever the machine is producing ionizing radiation. Appropriate radiation shielding shall be installed on each x-ray diffraction machine. These shields should be interlocked to prevent radiation exposure to personnel in the event the shield is removed or opened.
