Abstract:

This study evaluates the electromagnetic exposure safety of staff and passengers on subway platforms. Specifically, to identify electromagnetic exposure at typical waiting areas on elevated and underground subway platforms in operation, this study employed electric field-strength and spectrum analyzers to measure the signal power and e-field strength at typical waiting areas on subway platforms, and representative sources of radiation were selected. The results revealed that the peak measuring frequency from the main electromagnetic radiation source of subway platforms was in the range of 869~2 613 MHz. In addition, the e-field strength of the underground and elevated platforms was 0.010~0.044 and 0.009~0.098 V/m, respectively, which were far less than the reference levels defined by the International Commission on Non-Ionizing Radiation Protection guidelines for occupational and general public exposure. Thus, this study shows that the electromagnetic environment of a subway platform is not harmful to the health of subway staff and passengers.
