Radiofrequency Exposure Levels from Mobile Phone Base Stations in Outdoor Environments and an Underground Shopping Mall in Japan

Abstract

Overview

Recent advances in wireless technology have amplified concerns about health risks from electromagnetic fields (EMFs). Given this backdrop, a significant project was initiated in Japan in 2019 aimed at better understanding EMF exposure in day-to-day environments.

Findings

• A comprehensive study was conducted to measure electric field (E-field) strength in both 2019 and 2020, comparing these results with earlier data from 2006 and 2007 facilitated by the Ministry of Internal Affairs and Communications, Japan.
• Measurements were taken at multiple sites including outdoor urban and suburban areas, as well as an underground shopping mall, assessing the variation over time.
• Results showed that current E-field strengths are generally higher than past data, indicating a potential increase in EMF exposure in public spaces, particularly in the underground shopping mall.
• Despite these increases, the median levels remain significantly below the limits set by Japanese radio wave protection guidelines which suggest attenuation of risk; however, public health concerns persist due to ongoing exposure.

Conclusion

This study illustrates a rising trend in EMF exposure in various environments. It underscores the need for ongoing monitoring and comprehensive risk communication regarding EMF exposure to ensure public health and safety.
