  2. Warning signs must be affixed on the outside of the room, on the door that provides access to the equipment. The sign must be clearly legible and visible at a distance of 2 meters to personnel approaching the room door. Warning labels must be affixed to the equipment;
  3. The operation of an X-ray tube should be controlled from the control panel located outside the radiography room or behind a protective barrier;

  5. Warning light and/or sound must be provided when the X-ray tube is energized;
  6. A room must not be used at the same time for more than one radiological investigation. The equipment should be located in a locked room that can be entered only by authorized users. If equipment must be located in unrestricted areas, appropriate barriers should be installed and a key control switch must be installed to prevent unauthorized use;
  7. All operators must wear personal dosimeters and keep as far away from the X-ray beam as is practicable at all times. Direct radiation exposure to an individual for training purposes must never be allowed. Radiation exposure report must be kept for at least three years;
  8. Lead shielding, such as a lead apron and collar, must be provided for all exposures on patients;
