  • Title: [Electromagnetic hazards from electrosurgery--assessment of occupational exposure to electromagnetic field and currents induceed in the body].

    Abstract:
    The investigation of the occupational exposure to electromagnetic fields from electrosurgery devices were done (according to the requirements of Polish Standard PN-T-06580:2002). The exposure was evaluated following the criteria established by occupational safety and health regulations. The measurements and evaluation of the currents flowing through the exposed workers body were also conducted following the method and criteria published by IEEE standard and European Directive 2004/40/EC. It was found that in the vicinity of electrosurgical devices, the area of electromagnetic fields to which only workers operating the source of field should be exposed can exist up to the distance of 70 cm from the active electrode and supplying cables. In the case when the cables are placed directly on the surgeon body or long duration of the daily exposure the overexposure of workers can appear (referring to Polish regulations). The current flowing through the arm of surgeon keeping the electrode with electric field of the maximum strength (app. 1000 V/m or higher) can exceed permissible value of 40 mA established by the Directive 2004/40/EC for contact current. The reduction of the surgeon exposure can be reached by the proper positioning of the cables supplying monopolar electrode or by the use of bipolar electrode.
