# Safety Code 6 uncontrolled reference level, 300–6000 MHz

> Frequency-dependent power density of 0.02619 f^0.6834 W/m² (f in MHz) — 4.56 W/m² at 1900 MHz and 5.42 W/m² at 2450 MHz, so Canada is somewhat stricter than ICNIRP across the cellular and Wi-Fi bands.

## Key values

- **Limit value:** 1,290,000–1 × 10^7 µW/m² — Guideline value — scientific recommendation — Safety Code 6 (2015) Table 5, uncontrolled environments. The range is the band edges: 1.29 W/m² at 300 MHz to 10 W/m² at 6000 MHz. Worked values inside the band: 4.56 W/m² at 1900 MHz, 5.42 W/m² at 2450 MHz, 6.92 W/m² at 3500 MHz. The equivalent electric field is 3.142 f^0.3417 V/m (41.5 V/m at 1900 MHz). [hc-safety-code-6, hc-safety-code-6-pdf]
