Abstract

Overview

This study investigates the exposure of children aged five to fourteen to a 50 Hz homogenous magnetic field of uncertain orientation. It utilizes stochastic dosimetry to assess the effects.

Findings

  • Surrogate models were employed to determine how varying orientations of the magnetic field affect the electric fields induced in both the central nervous system (CNS) and peripheral nervous system (PNS) among these children.
  • The electric fields induced were found to be within the International Commission on Non-Ionizing Radiation Protection (ICNIRP) basic restrictions for the general public.
  • Analysis confirmed that there was no significant difference in exposure levels among children of different ages across 10,000 potential magnetic field orientations.

Conclusion

A “mean stochastic model” was developed to estimate exposure levels in each tissue of a representative child within this age range. Ultimately, the study enhances understanding of extremely low frequency magnetic fields (ELF-MF) exposures under variable and uncertain conditions, aiding in more realistic characterizations of EMF exposure risks.
