%X Objectives. To evaluate the effects of ionising radiation and radiation limits, and measure radiation doses received by surgeons in theatre. Design. Thermoluminescent dosimeter measurements of accumulated dose to specific anatomical regions of a neurosurgeon, gastroenterologist and orthopaedic surgeon performing fluoroscopy on 39 patients undergoing treatment for back pain, 7 for endoscopic retrograde cholangiopancreatography procedures, and 48 for orthopaedic operations respectively. Results. Radiation dose levels with the X-ray tube above the table during back pain procedures exceeded the occupational annual recommendation to the neurosurgeon¡¯s hands. The protocol regarding the orientation of the C-arm was changed. Convincing evidence of the importance and effectiveness of lead shielding was recorded. Conclusions. Constant revision of protocols should apply the as-low-as-reasonably-achievable principle in every unique setting. The ideal is to position the image intensifier above the theatre table. The longest possible distance from the source will lower radiation risk. Full-body protection of 0.35 mm lead equivalence during fluoroscopy is mandatory.
