Extremely Low Frequency Magnetic Fields in the Work Environment

In this paper we present measurements of the magnetic flux density in an office and three different welding environments. The measured values are compared with the thresholds set by the EU Directive 2013/35/EU. For the office environment, a magnetic field survey is presented at different heights with the electrical appliances operating in different modes. For the welding workshop, measurements were taken in the proximity to the welder during different welding practices. On comparing the magnetic flux density results for both environments with the low Action Levels stated in the EU Directive for occupational exposure, there is evidence that the measured values are below the safety threshold.
