# Building Biology SBM-2024 RF band: no anomaly

> Below 0.1 µW/m² peak per RF source in a sleeping area is graded 'no anomaly' — a precautionary target eight orders of magnitude below the FCC limit.

## Key values

- **Limit value:** 0–0.1 µW/m² — Precautionary value — not law anywhere — SBM bands per single source, peak measurement: <0.1 no anomaly, 0.1–10 weak, 10–1000 strong, >1000 extreme anomaly. These are assessment grades, not exposure limits. [sbm-2024]
- **Quantity:** power density
- **Frequency band:** per single RF source, peak
- **Population:** sensitive
- **Set by:** Building Biology SBM-2024 evaluation guidelines (2024)
