ICNIRP at WHO IAC on NIR 2025

Every June, the World Health Organization’s International Advisory Committee (IAC) holds its annual Meeting on Non-Ionizing Radiation. This year, the meeting took place online from 17–19 June. 

Dr. Akimasa Hirata provided a comprehensive update on ICNIRP’s ongoing activities in both electromagnetic fields (EMF) and optical radiation.

He first reported on the progress of one Standing Committee and five Project Groups (PGs) for EMF. The newly established Standing Committee on Communication focuses on enhancing stakeholder engagement and transparency. Its initial work clarifies ICNIRP's activities in the context of the United Nations Sustainable Development Goals.

The revision of the low-frequency guidelines (0–100 kHz) is progressing through three systematic reviews—human experimental, human observational, and in vitro/in vivo/in silico studies—to ensure a robust scientific basis. In parallel, a dosimetry review addresses key technical aspects needed for the guideline update.

The Radiation Protection System project, partly in collaboration with WHO and ICRP, examines conceptual differences between ionizing and non-ionizing radiation protection frameworks. A related workshop is scheduled for 2025 (ICRP). The Sub-THz Gap project investigates discrepancies around 300 GHz across RF, laser, and incoherent light guidelines, aiming to identify data needs for future revisions. The Environment and EMFs project evaluates whether current human exposure limits adequately protect wildlife and ecosystems.

Finally, Dr. Hirata introduced three optical radiation projects: a review on long-term UV exposure effects on skin and eyes, and revisions of both the Laser Guidelines and the ICNIRP Laser Pointers Statement.

ICNIRP is grateful for the valuable opportunity provided by the WHO team lead by Emilie van Deventer to share insights on its work and contribute to the advancement of NIR protection alongside WHO and experts from around the world.
