Non-Ionizing Radiation Safety (non-laser)

The modern world is full of devices which, either directly or indirectly, act as sources of non-ionizing radiation (NIR). These sources produce NIR in the electromagnetic spectrum of wavelengths/frequencies ranging from 100 nm to static fields. Many NIR sources are present on the UC Berkeley campus, either in research applications or in ancillary equipment.

In general, NIR tends to be less hazardous to humans than ionizing radiation (ionizing radiation has a wavelength less than 100 nm or a photon energy greater than 12.4 electron Volts). However, depending on the wavelength/frequency and the irradiance (or power density) value, NIR sources may present a human health hazard.

The Non-Ionizing Radiation Safety Manual is intended to provide guidance in maintaining a safe NIR work environment on the campus. Please contact Eddie Ciprazo at (510) 643-9243 if you need additional information.
