Background: Radio-frequency electromagnetic fields (RF-EMFs) are utilized in communications and appliances and are indispensable in daily life. However, some people have concerns about the adverse health effects of RF-EMFs; therefore, effective risk communication (RC) is needed in this field.
Objective: In this study, we investigate public attitudes towards RF-EMFs and examine the impact of RC via a website on these attitudes and objective knowledge.
The opportunities for exposure to radiofrequency electromagnetic fields (RF-EMF) among children are increasing. Children's exposure to RF-EMF in Japan was recorded using a personal exposure meter (ExpoM-RF), and factors associated with the exposure examined. A total of 101 children, aged 10-15 years old, participated in the prospective birth cohort "Hokkaido study".

- The study aims to evaluate electromagnetic field (EMF) exposure among library workers in Japan, particularly focusing on intermediate-frequency and pulsed EMF, to develop a new research methodology for epidemiological studies.
- The assessment involved measuring short-term (E1-E3) and mid-term (D1-D3) exposure scenarios based on the proximity to electromagnetic surveillance gates and anti-theft devices, using guidelines from the International Commission on Non-Ionizing Radiation Protection (ICNIRP).
- Results showed that none of the measured exposure scenarios exceeded ICNIRP guidelines, with most participants reporting low exposure levels, though a few had significantly higher values.
Exposure to magnetic fields from the electronic article surveillance (EAS) gate was evaluated in consideration of the application to epidemiological studies of library workers who are exposed continually to intermediate frequency magnetic fields from the EAS gate. Two types of exposures were investigated. One was transient exposure due to passing through or beside the gate and another was chronic exposure in the room.

Recent progress in wireless technologies has made human exposure to electromagnetic fields (EMFs) increasingly complex. The situation can increase public concerns related to possible health effects due to EMF exposure. Monitoring EMF exposure levels and characterizing them are indispensable for risk communications of human exposure to EMFs.
