Introduction: Recent industrial developments have led to the rapid development of electricity production successively; it leads to power grids and high voltage utilization. The effects of electromagnetic fields have been investigated on the organism by researchers. In many cases, it is not possible to conclusively comment, because of the slowness impact of fields of life-cycle processes and the long-term studies. According to the harmful effects of exposure to electromagnetic waves, this study was conducted to investigate the electric field intensity and magnetic field at high voltage substations (230 kv) in Golestan province.
Materials and Methods: This Cross-sectional study (descriptive-analytical) was performed at 230 kv substations in Golestan Province (1396). The electric field and the magnetic field density were measured by instrument model TM-190 at 5 posts in Golestan province and compared with the standards.
Results: 100 % of the measured electric field intensity and magnetic field of the 230 kv substations in Golestan Province is less than the standard.
Conclusion: The magnitude of the electric and magnetic fields is in the occupational limits.
