Abstract

Overview

This study addresses the ongoing debate regarding the potential health hazards of mobile phone (MP) use. Predominantly, it focuses on the lesser-studied aspect of static magnetic fields (SMF) emitted by MPs, in contrast to the extensively studied radiofrequencies (RF).

Findings

• Utilization of a tri-axis magnetometer allowed for the creation of 2D maps of the SMF at various distances from the screens of five mobile phone models produced between 2013 and 2018.
• A mathematical model was developed to fit the measurements, estimate the SMF down to the phone screens, and calculate potential exposure to the SMF on the skin of a 3D head model, with exposures ranging in the µT to mT scale.
• The study underscores the necessity for further research into the biological effects of combined SMF, Extremely Low Frequency (ELF), and RF fields, as these combined exposures reflect more realistic usage scenarios and therefore, potential risks.

Conclusion

The findings advocate for the serious consideration of static magnetic fields as a significant variable in health risk assessments, given their potential to cause adverse biological effects including the induction of reactive oxygen species (ROS). The interaction mechanisms, particularly involving magnetite nanoparticles found in the brain and its potential impact on tinnitus and other conditions, warrant deeper investigation.
