People are exposed to NIR in naturally occurring situations, for example to the magnetic field of the earth and to radiation from the sun. Within the last century individual’s NIR exposure has increased through the use of a wide array of technological applications that utilise NIR, such as electric appliances and communication devices.
ICNIRP expresses its protection recommendation primarily through the ICNIRP guidelines related to a specific frequency or wavelength band independently from the source. Read here how these recommendations translate for some common NIR applications.
