The modern world is full of devices that, 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 of less than 100 nm or a photon energy greater than 12.4 electron Volts). However, depending on the wavelength/frequency and...
