Abstract
Background & objeftive: Electromagnetic field comprises electric and magnetic fields which is produced by electricity current. Long term exposures to electromagnetic fields have some adverse health effects on exposed workers. Applications of equipment which create electromagnetic field are increasingly high. Therefore, the current study was carried out to evaluate electromagnetic fields in one of the oil product distribution company in Mazandaran province.    
Materials & Methods: In this cross-sectional study a real time EMF measurement device was used to evaluate electromagnetic field in the vicinity of computers’ monitors, cases, servers, copying machines, and also in electricity posts. Measurement was carried out in 28 sites and the results were compared with national and international standards.
Results: The average of electric field for all stations was 44.4 v/m and the maximum and minimum rates of electric field were 208 and 0.5 v/m related to copying machine and the electricity generator respectively. The mean magnetic field density was 61.7×10-6 mT for all studied sites. The highest magnetic field intensity (5.0×10-4 mT) was found in high voltage fuse box and the lowest (0.2×10-6 mT) was related to electricity control room.
Conclusion: The measured electric and magnetic intensity fields were lower than national and international standards.   As the intensity of evaluated electric and magnetic fields were lower than national and international recommended levels, the workers would exposed to safe level of electromagnetic field.
