NIOSH recommends that employee exposure to radiofrequency and microwave radiation in the frequency range of 300 kHz to 300 GHz be controlled to protect workers from thermal heating and possible nonthermal bioeffects.

Plain English Summary

Summary written for general audiences

The document reviews scientific information on radiofrequency and microwave radiation and recommends a standard for controlling workplace hazards. The recommended limits apply to frequencies from 300 kHz to 300 GHz and are averaged over any 6-minute period during a workshift of up to 10 hours.

Why This Matters

The document estimates that up to 21 million workers in the United States may be exposed to radiofrequency and microwave radiation. Further research is needed on long-term low-level animal studies, irreversible changes, interaction mechanisms, epidemiologic investigations, human absorption studies, and pulsing variables.

Quick Questions About This Study

The recommended standard covers radiofrequency and microwave radiation from 300 kHz to 300 GHz (0.3-300,000 MHz).
For 10-400 MHz the limit is a mean squared E-field strength of 3,770 V²/m² and a mean squared H-field strength of 0.027 A²/m², corresponding to 1 mW/cm² equivalent plane-wave power density, averaged over any 6-minute period.
The document calls for long-term low-level animal studies and determination of any irreversible changes from exposure. It also identifies a need for studies of interaction mechanisms and long-term epidemiologic investigations of exposed populations. Additional needs include human absorption characteristic studies and the importance of pulsing variables in biologic effects.
