Brazil's national amateur radio society LABRE reports the communications regulator ANATEL has published regulations on human exposure to electric, magnetic and electromagnetic fields

Published on 30th January 2019, Normative Act No. 458, dated 24th January 2019, establishing the technical requirements complementary to the Regulation on the evaluation of human exposure to electric, magnetic and electromagnetic fields associated to the operation of radio communication transmitting stations (CEMRF), approved by Resolution No. 700 of 28th September 2018.

As a matter of great concern to all amateurs, ANATEL's original proposal considered the criterion of simplified theoretical calculation of the minimum distances of amateur radio antennas to be exempt from the compliance report, but with formulas that practically tripled the distances.

Among the proposals accepted during the public consultation phase is the one sent by LABRE for the maintenance of the formulas of Resolution 303 for the specific conditions for amateurs, reinforcing that they already corresponded to conservative criteria, with expressions recognized by the International Telecommunication Union, among other arguments.

Thus, radio amateurs will continue to follow the same distance calculations applied by the former Resolution 303, republished in Act 458 (Table D.1).
