Abstract

Overview

The 2020 ICNIRP guidelines introduce updated restrictions to manage exposure to radiofrequency fields, replacing parts from both the 1998 and 2010 ICNIRP guidelines. This transition includes new metrics and expands coverages such as thermal and nerve stimulation effects.

• Introduction of new restrictions to prevent excessive heating and nerve stimulation.
• Implementation of more intricate metrics and provisions for exposure measurement.

Findings

Significant changes include the introduction of restrictions for brief local exposures and different parameters used for various exposures. There are now precise limits set for both occupational and general public exposure.

• Whole-body and local specific absorption rate (SAR) guidelines have been updated.
• Power density restrictions have shifted from incident power density to absorbed power density to better reflect the interaction with the body.

Conclusion

The detailed updates in the 2020 ICNIRP guidelines enhance the protection system's complexity, which could complicate practical applications and compliance assessments. Greater emphasis on training for professionals and development of measurement tools tailored to these guidelines is crucial.
