Radiofrequency and Microwaves: Environmental Health Criteria 16

Microwave and radiofrequency (RE) radiation constitute part of the whole electromagnetic spectrum. This document is concerned with frequencies lying between 105 and 3 × 1011 Hz (100 kHz and 300 GHz). The term radiofrequency refers to the range 100 kHz- 300 MHz (3 km to 1 m wavelength in air) and microwaves to the frequency range of 300 MHz-300 GHz (1 m to 1 mm wavelength in air).
