Researchers measured the radiation exposure to the surgeon by utilizing digital dosimeters placed at the level of thyroid/eye, chest and dominant forearm. The average radiation exposure to the surgeon during open cases was 0.16±0.22 mR (thyroid/eye), 0.21±0.23 mR (chest) and 0.20±0.14 mR (hand).
For the minimally invasive cases, surgeons were exposed to 1.72±1.52 mR (thyroid/eye), 3.08±2.93 (chest) and 4.45±3.75 (hand). Additionally, surgeons standing in an adjacent substerile room during the open cases were exposed to 0.2 mR per case.
A surgeon can perform 1,623 minimally invasive microdiscectomies to exceed the exposure limit for whole-body radiation, 8,720 cases for the lens of the eye and 11,235 cases for the hand.
