From May 5: http://www.arrl.org/news/arrl-helps-radio-amateurs-comply-with-new-rf-exposure-evaluation-rules:
The National Association for Amateur Radio® provides free, comprehensive resources to help radio amateurs ensure they are compliant with the new RF exposure rules.
On May 3, 2021, new FCC rules governing RF exposure evaluations went into effect. While the exposure limits were not changed, the requirement to conduct an evaluation was made more broadly applicable to amateur licensees. A 2-year transition period was implemented to allow existing amateur licensees to conduct evaluations and make any changes necessary to ensure that their station complies with the exposure rules. On May 3, 2023, the transition period ended. All licensees must now conduct evaluations of their current station and reassess compliance when making changes to their stations that would affect exposure going forward.
As detailed in a May 2023 QST article by Greg Lapin, N9GL, the rules now require amateur radio operators to perform station evaluations. The Amateur Radio Service is no longer categorically excluded from certain aspects of the RF exposure rules, and licensees can no longer avoid performing an exposure assessment simply because they are transmitting below a given power level.
The ARRL website features an RF Exposure landing page with resources, such as an RF exposure calculator, the entire RF Safety section from the 100th Edition of the ARRL The Handbook, a video explaining the topic, FAQs about the subject, and more. These tools and resources are available to the public without an ARRL membership or website account.
For further assistance with technical matters, ARRL members enjoy the additional resources of the ARRL Technical Information Service, and access to the experts within the ARRL Lab.
