Abstract

Overview

High exposures to radiofrequency electromagnetic fields (RF EMF) are prevalent in various occupational environments. This systematic literature review aims to analyze these exposure levels in different sectors with sources used for diverse purposes.

Findings

• Workplaces involved include broadcasting, telecommunication, security and identification sectors, and industries focusing on remote sensing, and the heating and drying of goods.
• The review compiles data from peer-reviewed publications and grey literature, targeting the highest measured electric field strengths, magnetic flux densities, and power densities.
• Instances of maximum exposures surpassing occupational safety limits are particularly highlighted in sectors like dielectric heating and security scanners.

Conclusion

Although cases of exposure exceeding recommended limits are infrequent in areas such as microwave heating and radar, there are documented cases of thermal health effects after occupational accidents, necessitating ongoing monitoring and reassessment, especially with emerging technologies like fifth generation telecommunication systems and the energy transition.
