Evaluation of ELF-MF Exposure Levels for Elementary School Students in Indoor and Outdoor Environments

Abstract

Abstract This research investigation is focused on evaluating the possible health concerns that may arise for elementary school students due to their proximity to transmission and underground lines near their school. The primary goal of this research is to measure extremely low-frequency magnetic field (ELF-MF) levels during school hours and various other times of the day to ensure that these levels are in accordance with established safety standards, thereby safeguarding the well-being of both students and the school community. A total of 32 personal exposure measurements were collected from elementary students in the Gyeonggi-do region. These measurements encompassed a continuous 24-hour period, covering time spent at school, at home, during extracurricular activities, and in daily life. Some students displayed noticeable spikes in ELF-MF values, particularly during non-school hours, with levels reaching as high as 13.96 µT. This study underscores the significance of acknowledging the possible health risks associated with ELF-MF exposure stemming from common household devices. It emphasizes the importance of consistently maintaining and responsibly using microwave ovens and other electronic appliances to mitigate such risks. Furthermore, the research underscores the necessity for proactive measures aimed at minimizing children's exposure to ELF-MF within the school environment.
