ICNIRP has been working on its new high-frequency (HF) guidelines, which will cover the 100 kHz – 300 GHz range of the non-ionizing radiation (NIR) spectrum. This will replace the HF portion of the 1998 ICNIRP guidelines. A draft of the new HF guidelines was presented at ICNIRP’s 8th International NIR Workshop in Cape Town, South Africa, in May 2016. This provided an opportunity to share the direction of the ICNIRP thinking, and to obtain preliminary comments from the Workshop participants. At that time ICNIRP was planning to have a public consultation document ready by the end of 2016. However, as some of the issues that were raised regarding the HF guidelines are requiring considerable additional thought and development, this time frame is no longer feasible. ICNIRP will provide updates on the progress in due course.
