- Limit value
- 2,000,000–1 × 10^7 µW/m²Regulatory value — legally enforceable — Brazil does not set an independent numerical value: Lei 11.934/2009 adopts the limits recommended by the WHO, and Ato 17.865/2023 puts the ICNIRP values in force in Anatel's technical requirements. The range is the band edges, 2 W/m² at 400 MHz to 10 W/m² at 2000 MHz.sources: brazil-anatel-ato-17865, brazil-lei-11934
