The International Commission on Non-Ionising Radiation (ICNIRP) is based in Germany. Its mission is to disseminate information and provide advice on the potential health hazards of exposure to non-ionising radiation.
ICNIRP guidelines cover frequency ranges from 1 Hz to 300 GHz. Guideline releases in 2009 and 2010 cover frequency ranges from 1 Hz to 100 kHz.
ICNIRP distinguish multi-point central nervous system (CNS) effects for the head – and for the peripheral nervous system (PNS) being the rest of the body and give different basic restrictions for each. They also set different values for public exposure from occupational exposure and need to be monitored in multi-layer format.
Reference levels are based on both CNS and PNS effects, with bias towards whichever is the more onerous at the frequency concerned. These are not maximum limits, they are guidance figures for when it is necessary to investigate the basic restriction in further detail.
Maximum levels are also set as “Exposure Limits” which must not be exceeded. At these levels employers must take imminent action without delay. This may result in machine equipment being revoked or replaced.
