ICNIRP aims to protect people and the environment against adverse effects of non-ionizing radiation (NIR). To this end, ICNIRP develops and disseminates science-based advice on limiting exposure to non-ionizing radiation. Experts from different countries and disciplines such as biology, epidemiology, medicine, physics, and chemistry, work together with and within ICNIRP to assess the risk of NIR exposure and provide exposure guidance. ICNIRP experts base their advice on scientific publications about biological effects and action mechanisms of radiation, for the whole NIR frequency range. ICNIRP’s protection advice is formulated in its Guidelines, Reviews and Statements, which are publicly and freely available online. ICNIRP also organizes workshops to inform about current scientific knowledge and to provide an opportunity to advance the dialogue on NIR protection.
