Calculation of Dental Exam Room X-Ray Shielding in Walls and Entrances

Abstract

The U.S. Air Force School of Aerospace Medicine, Radiation Health Consulting Branch (USAFSAM/OEC), performed an assessment of the x-ray shielding design of a newly designated dental exam room at the 113 WG/MDG. In accordance with AFI 48-148, Ionizing Radiation Protection, and NCRP-116, Limitation of Exposure to Ionizing Radiation, persons in uncontrolled areas should not receive a dose in excess of 100 mrem/yr. USAFSAM/OEC recommends using specialty shielding on all walls that includes 3.0-mm lead. The door and window should both be replaced with specialty fixtures that incorporate shielding materials equivalent to 3.0-mm lead. If these are used, the primary barrier design is sufficient to prevent personnel from exceeding the 100 mrem/yr limit (based on the supplied information and stated assumptions).
