New EU changes from ICNIRP Main Help page UK Help page
Current Software Release: v0.1  ( 2021-04-23 ). Current Help Release: v0.1  ( 2021-04-23 )


2020-03-11 ICNIRP publishes revised guidelines (with detailed 1998 to 2020 differences) on limiting exposure to electromagnetic fields.
"Guidelines for limiting exposure to electromagnetic fields (100 kHz to 300 GHz)"

An existing calculator for 1998 guidelines is available, ICNIRPcalc (v1.5 ) from Thilo Kootz, DL9KCE. It is available from IARU Region 1 site (caution, link to zip file).
A version taking into account the changes for ICNIRP 2020 guidelines [Say, ICNIRPcalc2020 (v-.- )] is not available for download and any proposed update is NOT coming at this time.

I have been in touch with Thilo and his answer is:

"I am aware of the fact that ICNIRP has been changed. In the EU, we have had a Recommendation to all members states since 1999. This Recommendation still holds and is transferred to national law in most of the EU states. ICNIRPcalc is based on those limits and until the EU changes their recommendation, most of the member states will not either".

What does this mean for amateur radio? A lot, because it's the first time that radio amateurs don't have special exceptions or exemptions in some way. They existed because of the almost infinite number of situations and supposed 'solutions' in most amateur configurations. The use of a truly online calculator (or one that says it's "online" but is downloaded and run locally in a spreadsheet or as a local executable) simply CANNOT in any way model anything but the simplest of situations. Parodoxically, it means nothing except for a "warm fuzzy feeling" that the FCC, Ofcom, etc. have done something to address an oddity in the use of parts of the radio spectrum. So, go through the motions to the best of your ability, stash away your results and get on with things. Just hope that they don't tighten things further in the forseeable future. Field modelling is sophisticated and expensive in time and money. It's sad that 5G is what triggered these changes because of exposure on 'social media' and bad press. Before this, few people thought of RF Exposure except for cell towers being placed at or near schools, which was mostly 'folly'.
