Hazard of ionizing radiation to trauma surgeons: reducing the risk.

Abstract

A study aimed to establish the level of radiation exposure to orthopaedic surgeons involved in the care of injured patients; parts of the body most at risk, and to establishing whether surgeon control of X-ray image intensification reduced the risk. This was conducted on five orthopaedic surgeons regularly involved in musculoskeletal care. Radiation dosage (in millisieverts (mSv) to the body, neck, eyes and hands, was measured by means of dosimeters applied to these areas, before and after surgeon-controlled use of X-ray image intensification. Although all doses measured were within current safety guidelines (1.25 mSv total body dose/month, 3.75 mSv eye dose/month and 12.5 mSv extremity dose/month), the hands were most at risk (maximum recorded dosage 3.95 mSv/month). Control by the surgeons of X-ray image intensification significantly reduced exposure of the hands (P < 0.05).
