General approach to protection against non-ionizing radiation.

This document explains the approach that ICNIRP uses in providing advice on protection against non-ionizing radiation (NIR) exposure to serve both as a guide for the understanding of ICNIRP’s documents and for its future work. The activities of ICNIRP are delineated, and the relationships with other advisory and legislative bodies are described. Furthermore, ICNIRP’s current general approach to the assessment of health risks as a basis for the development of guidelines on limiting exposure is explained. Issues dealt with by ICNIRP relate to optical radiation (ultraviolet, visible and infrared) including lasers and electromagnetic fields (microwaves, other radiofrequency fields and fields of lower frequencies down to and including static electric and magnetic fields). Ultrasound and infrasound exposures may also be considered.
