ICNIRP is an independent organization that develops science-based guidelines to limit non-ionizing electromagnetic exposure, including RF, UV, infrared, and ultrasound. It aims to protect public health by providing evidence-based advice on the safe use of electromagnetic fields across various technologies.
The International Commission on Non-Ionizing Radiation Protection (ICNIRP) is an independent scientific organization dedicated to providing guidance and recommendations on protection from non-ionizing radiation (NIR). NIR refers to electromagnetic radiation and mechanical waves that do not carry enough photon energy to ionize atoms or molecules. ICNIRP classifies NIR into various frequency and wavelength bands, including static magnetic and electric fields (0 Hz), low frequency (1 Hz to 100 kHz), radiofrequency electromagnetic fields (100 kHz to 300 GHz), infrared (780 nm to 1 mm), visible light (380 to 780 nm), ultraviolet (100 to 400 nm), and ultrasound (above 17.8 kHz acoustic). These classifications are used to develop exposure guidelines tailored for each band.
ICNIRP develops science-based exposure guidelines aimed at protecting human health from the potential adverse effects of NIR across frequency bands. These guidelines are independent of the source of exposure, focusing instead on the biological and physical characteristics of the radiation. The commission disseminates these guidelines via publications such as the well-known 2020 RF EMF guidelines (100 kHz to 300 GHz), which have been subject to ongoing scientific dialogue including responses to publications addressing 5G and electromagnetic field concerns.
ICNIRP also addresses identified knowledge gaps, such as those relating to radiofrequency exposure and the effects of airborne ultrasound generated by common industrial and domestic devices. Its activities include scientific research coordination, public consultations, and collaboration with global stakeholders to ensure up-to-date protection recommendations. Application areas range from medical imaging technologies and power lines to mobile communication devices, base stations, and emerging technologies such as 5G.
As a transparent and independent body, ICNIRP provides free access to its guidelines and statements on its website, alongside educational resources and annual reports. The commission acknowledges natural exposure to NIR from sources like the earth's magnetic field and solar radiation, noting that recent technological developments have significantly increased human NIR exposure. Overall, ICNIRP serves as a scientific authority on NIR protection, continually reviewing scientific evidence to update and improve safety standards worldwide.
