# Korea public magnetic limit at 60 Hz

> 83.3 µT (833 mG) at Korea's 60 Hz mains frequency — the ICNIRP 1998 reference level, which Korea kept rather than moving to the 200 µT figure of the 2010 revision.

## Key values

- **Limit value:** 83.3 µT — Regulatory value — legally enforceable — The general-public table gives B = 5/f µT with f in kHz for 25 Hz–0.8 kHz, which is 83.3 µT at 60 Hz; the RRA states the Korean power-frequency figure as 833 mG. Korea separately notes that 4 mG values quoted for Switzerland, the Netherlands and Denmark are installation or quality targets, not human-protection limits. [korea-emf-protection-standard]
- **Quantity:** magnetic flux density
- **Frequency band:** 60 Hz
- **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
- **Frequency-dependent formula:** 5/f µT for 25 Hz–0.8 kHz (f in kHz)
