Exploring Radiation Safety in Commercial mmWave Radar Systems: Insights from Novelic
Radiation Safety in Commercial mmWave Radar Systems
Key Highlights:
Ionizing Radiation: mmWave radar operates at 20-80 GHz, with energy levels (~0.1 meV) that are 6 orders of magnitude below ionization thresholds, making them non-ionizing and safe from atom disruption.
Thermal Effects: mmWave signals cause heating due to energy absorption, but modern radars emit power levels far below hazardous thresholds:
- Industry limits: 10 W/m² (general public) and 50 W/m² (occupational exposure).
mmWave devices typically operate at 100 mW peak transmission, well below these levels.
Skin Absorption: Up to 90% of mmWave energy is absorbed by the skin’s outer layers, causing localized heating (~1°C at 60 GHz and 50 W/m²). Energy diminishes significantly with depth and clothing layers.
Eye Absorption Studies: Research on nonhuman primates and rabbits confirms:
- Exposure exceeding regulated limits can cause transient corneal effects, typically reversible within hours or days.
- Low-power radar systems are unlikely to pose significant risks.
Insights: Adhering to established standards ensures mmWave radar systems are safe for human use, with radiation impacts negligible compared to everyday sunlight exposure. Modern radars are designed as low-power, energy-efficient devices well within safety guidelines.
