Abstract: (32 Views)
Background and Objective: This study investigated the spatial distribution of electric and magnetic field intensities around 63 kV high-voltage power lines located in a public park in Qazvin, Iran. The aim was to evaluate citizens’ exposure to extremely low frequency (ELF) electromagnetic fields through experimental measurement and numerical modeling.
Materials and Methods: This descriptive-analytical research measured electric and magnetic field strengths around 63 kV pylons in four directions and various distances at typical human height (170 cm) across all seasons. Measurements were conducted using a calibrated Holaday field meter during peak power consumption periods. Three-dimensional field propagation was modeled using the COMSOL Multiphysics software and the finite element method (FEM). The obtained data were compared to Iranian national exposure standards and analyzed statistically using R software and the generalized estimating equation (GEE) model.
Results: The intensities of both electric and magnetic fields were highest near the pylons and decreased with increasing distance. The maximum electric field values occurred in spring and summer, while magnetic field maxima appeared in winter. Temperature and humidity exhibited significant effects on the field intensities (p< 0.05). Modeled values were higher than measured ones. Nevertheless, all measured values were below the permissible limits defined by Iranian national standards.
Conclusion: The exposure level of visitors to electromagnetic fields within the studied park was found to be within safe limits and below the national health thresholds. Considering seasonal variations and environmental influences, periodic monitoring throughout the year is recommended. Utilization of natural elements such as vegetation can effectively reduce local field exposure.
