## Key values

- **Limit value:** 2,000,000–1 × 10^7 µW/m² — Regulatory value — legally enforceable — The range is the band edges: 2 W/m² at 400 MHz to 10 W/m² at 2000 MHz. At 900 MHz the limit is 4.5 W/m², equivalently 41.25 V/m. [korea-emf-protection-standard]
- **Quantity:** power density
- **Frequency band:** 400–2000 MHz
- **Population:** general public
- **Set by:** Korea EMF human protection standard (전자파 인체보호기준) (MSIT Notice No. 2019-4 under Radio Waves Act art. 47-2)
- **Kind:** Regulatory — legally enforceable
- **Averaging time:** 6 minutes — A measurement must use the same averaging before it can be compared with this value.
