In this study, we measured the time variation of electric fields leaked from a heating device in the ion cyclotron range of high-frequency in an experimental fusion facility, and analyzed their statistical characteristics. As a result, we found that the electric field variation with time is very small and the maximum electric field level is only 1/30 of the ICNIRP safety guideline. However, the instantaneous field variation is very violent so that it may reach 140,000 times in one second to cross some field level. In addition, we also evaluated the possibility of electromagnetic inference to an implanted cardiac pacemaker in the measured electromagnetic environment. It is found that even in the worst case the interference voltage induced in the output of the pacemaker sensing circuit does still not exceed the threshold for a malfunction. |
