The International Commission for Non Ionizing Radiation Protection (ICNIRP) has provided an update on the revision of the HF guidelines advising

ICNIRP’s current guidelines for the high-frequency (100 kHz – 300 GHz) portion of the electromagnetic spectrum were published in 1998. Given the large body of relevant research that has been generated since those 1998 guidelines, ICNIRP is now revising the guidelines to incorporate this literature.

The revision of the guidelines has been underway since 2014, and a public consultation version of the updated guidelines is expected within the first half of 2018.

More information on the revision is available on the ICNIRP web site https://www.icnirp.org/en/activities/news/news-article/revision-of-hf-guidelines-2017.html
