Testing Types Explained
- Short-Term Tests
- Purpose: Quick results to detect high radon levels.
- Methods: Charcoal canisters, electret ion detectors.
-
Limitations: Prone to false negatives due to environmental factors (e.g., humidity).
-
Long-Term Tests
- Purpose: Accurate radon level tracking over time.
- Methods: Alpha Track Detection (measures alpha particles from radon decay).
-
Benefit: Reliable, with less susceptibility to external influences.
-
Continuous Radon Monitors (CRMs)
- Features: Battery-powered or plug-in devices with mobile app tracking.
-
Best for: Monitoring radon fluctuations over time.
-
Water Testing
- Usage: Ideal for homes using well water, as radon can seep into water supplies.
- Note: Boiling water removes radon from liquid but releases it into the air.
DIY vs. Professional Testing
| DIY | Professional |
|-----------------------------------|----------------------------------|
| Inexpensive ($100–$200) | More expensive ($700–$1,200) |
| Lower accuracy | High accuracy and reliability |
| Not accepted for official records | Suitable for real estate or legal purposes |
| Best for preliminary checks | Ideal for definitive results |
When to Test for Radon
- After Home Renovations
- E.g., basement refinishing, new insulation installation.
- Before Selling or Buying a Home
- Ensures compliance with legal or insurance requirements.
- Living in High-Risk Areas
- Radon levels vary regionally, especially in areas with high uranium content in soil.
Tips to Save Money
- Bundle Services: Combine radon testing with other home inspections for discounts.
- Use Continuous Monitors: Reusable and cost-effective for long-term tracking.
- Limit DIY: Only use as a temporary solution if professional help is unavailable.
- Assist Professionals: Offer to help with setup (e.g., clearing furniture) to reduce labor costs.
Why Radon Testing Matters
- Radon is the second leading cause of lung cancer in the U.S.
- Found in basements and well water, radon often requires mitigation to ensure safety.
Testing is a small price to pay for peace of mind and health protection.
