4. Operating Instructions
4.1 Placement Guidelines
For optimal accuracy, place the HOUND-1011 in areas where radon levels are most likely to be present or where occupants spend significant time. Use the integrated stand for stable placement.
- Recommended Locations: Basements, ground-floor living areas, bedrooms, and other frequently occupied spaces.
- Avoid: Areas near windows, vents, fans, fireplaces, or in bathrooms with high humidity. Keep away from direct sunlight and heat sources.
- Ensure the device is placed at least 20 inches (50 cm) above the floor and 8 inches (20 cm) from walls.

5.2 Interpreting Radon Levels
Radon levels are typically measured in pCi/L (picocuries per liter) or Bq/m³ (becquerels per cubic meter). The Environmental Protection Agency (EPA) provides guidelines for interpreting these levels:
| Radon Level | Recommended Action |
|---|---|
| 0-2 pCi/L | Regular monitoring recommended. |
| 2-4 pCi/L | Consider enhancing ventilation. |
| 4+ pCi/L | Professional radon mitigation recommended. |
It is important to note that radon levels can fluctuate daily and seasonally. Long-term monitoring provides a more accurate representation of average exposure.
