ABSTRACT Our research project aims to clarify actual human exposure levels to radio frequency electromagnetic field (RF‐EMF) in daily life, as well as investigate risk communication methods using the RF‐EMF exposure levels. In this project, we conducted to measure the micro‐environmental RF‐EMF exposure levels across surrounding different environments which are major railway station areas, shopping streets, residential areas, public parks in urban and suburban areas because of acquiring the detailed data supporting an understanding of the micro‐environmental personal RF‐EMF exposure levels in Japan. Additionally, in order to evaluate a measurement method using a portable measuring device, we conducted measurements by traversing a designated route way and back. The results showed that RF‐EMF exposure levels in urban areas were significantly higher than those in suburban areas. Among the surrounding environments, the major railway station areas had the highest RF‐EMF exposure levels, followed by the shopping streets, the residential areas, and the parks. Furthermore, the micro‐environmental RF‐EMF exposure levels by the way‐and‐back measurement showed no significant difference between them. The results of these measurements confirm that outdoor mobile measurements using a portable measurement device are effective for assessing micro‐environmental RF‐EMF exposure levels during daily activities.
