Purpose: The study aims to provide basic data to enhance the health of paramedics responsible for patient transport and treatment by analyzing the exposure level of paramedics to electromagnetic waves generated by electric devices used in ambulances.
Methods: The study measured electromagnetic waves in ambulances in N region from July to December 2018. ME3030B produced by German Gigahertz Solutions was used to measure these waves and the maximum value was selected by moving it slowly in various directions. Each measurement part was selected and the mean value was calculated by repeatedly measuring at 10-minute intervals three times in total: 1st, 2nd, and 3rd phase.
Results: Among the electrical devices installed in the patient room of the ambulance measured at distances of 1 cm or 30 cm, results showed a high level of electric waves at the inverter (26.25±39 V/m) and high level of electromagnetic waves (564.00±31.75 nT) at the ozone sterilizer. According to measurements toward the front near the driver’s seat, results indicated high levels of electric waves (3.67±1.15 V/m) and electromagnetic waves (450.00±19.52 nT) at the black box hard drive.
Conclusion: Electromagnetic waves within the ambulance were stable and not beyond the range that might impact human health. However, in the case of the black box hard drive (3.67±1.15 V/m, 450.00±19.52 nT) located under the passenger seat, it may have a direct effect on the human body and, thus it is necessary to move it to a storage area further away from the paramedics to minimized the impact.
