The purpose of the present study was to reduce absorbed dose rates in air by means of the X-ray tube protector in the X-ray fluoroscopy room. We measured absorbed dose rates in air using an ionization chamber type survey meter, made the scatter radiation maps and worked out the reduction rate of absorbed dose rates in air. Absorbed dose rate in air reduced 75-90% with use of the X-ray tube protector. Especially, absorbed dose rate in air reduced 85-90% at the height of crystalline lens and thyroid gland of the X-ray technician near the patient. It was suggested X-ray protector could reduce the risk of radiation exposure of radiologists effectively.
