Abstract

Overview

This study focuses on the evaluation of electromagnetic field (EMF) exposure levels among library workers in Japan, particularly considering simultaneous exposure to intermediate-frequency EMF (IF-EMF) and pulsed EMF.

Methods

  • Assessment of multiple EMF sources such as electronic article surveillance gates and book check units at libraries.
  • Exposure scenarios include whole-body and local exposures with evaluations based on international safety guidelines.
  • Longitudinal data collection through web-based questionnaires.

Findings

Most of the exposure levels were found to be within international guideline limits, with only occasional instances exceeding these levels.

Conclusion

The study proposes a structured method for assessing EMF exposure relevant to epidemiological research, indicating mostly compliant levels but highlighting potential areas of concern for continuous and repeated transient exposures.
