[Objectivized evaluation of surgeons exposure to radiofrequency electromagnetic fields -- in the context of exposure duration and Polish and new international requirements regarding workers protection].
This occupational exposure assessment monitored surgeons during 11 surgeries using monopolar electro surgery units and measured electric and magnetic field strengths during cutting and coagulating modes. Electric fields near the cable at 10 cm were reported in the hundreds of V/m, while magnetic fields were <0.2 A/m. ESU active time during surgeries was shorter than workers declared, and the authors state that maintaining at least 15 cm distance from cables meets Polish exposure limits, while localized hand exposure needs further study.
Key points
- Surgeons' ESU exposure was monitored in real time across 11 surgeries using a monopolar ESU activity recorder.
- Electric field strength at 10 cm from the active-electrode cable ranged from 147β675 V/m (cutting) and 297β558 V/m (coagulating).
- Magnetic field strength was reported as <0.2 A/m in both cutting and coagulating modes.
- ESU operation time varied widely, with 5β66% over the first 3 minutes and 3β40% over the first 6 minutes of surgery.
- Across any 6-minute periods, ESU use was reported as 0β12% (median) and 7β43% (maximum).
- The authors conclude that a β₯15 cm distance between cables and workers meets Polish permissible exposure limits.
- The paper notes that localized hand exposure assessment requires detailed SAR distribution analysis and further studies.
