Background and Objectives: Electric andmagnetic fields in the workplace are one ofthe detrimental factors of power plants, transmission lines, electrical wires, and electrical equipments, therefore, exposure to these fields might be harmful for human health. This study aimed to provide information about intensity of the electromagnetic fields at the high voltage electricity posts and its comparison with the threshold limit value (TLV).

Materials and Methods: The study was conducted at one of the high voltage electricity post in Zanjan City having 63,230, and 400 KV power transmission lines. After identifying stations and measuring the intensity of these fields, GIS maps were prepared and the values were compared with permissible values.

Results: The measured magnetic flux density at different parts of the high voltage post showed that the lowest and highest intensity were 1.69 and 153.7 mG respectively which were …
