Key Radon Terms Explained for Idaho Homeowners
Radon conversations often include technical language that can make decisions harder than necessary. This glossary defines the terms you are most likely to see in radon testing reports and mitigation proposals.
Core Radon Terms
- pCi/L: picocuries per liter, the standard unit for radon concentration.
- Action level: EPA threshold of 4.0 pCi/L where mitigation is recommended.
- Short-term test: testing period typically used for quick screening.
- Long-term test: extended measurement that better captures seasonal variability.
- Mitigation: system installation to reduce indoor radon levels.
- Post-mitigation verification: follow-up testing to confirm reduction performance.
System Design Terms
- Sub-slab depressurization: active fan system that lowers soil-gas pressure beneath slabs.
- Suction point: entry location where sub-slab air is drawn into mitigation piping.
- Manometer: gauge used to verify system pressure differential.
- Fan stack: vent path that discharges radon gas above occupied zones.
