Radon
A naturally occurring radioactive gas produced by the decay of uranium in soil and rock. It is colorless, odorless, and tasteless.
Picocuries per Liter (pCi/L)
The unit of measurement for radon concentration in air. The EPA recommends taking action when radon levels exceed 4 pCi/L.
Sub-Slab Depressurization
The most common radon mitigation technique that involves creating a pressure difference beneath the foundation to prevent radon from entering the home.
Activated Carbon
A porous material used in radon mitigation systems to absorb radon gas from indoor air in certain types of water and air treatment systems.
Alpha Track Detector
A passive radon testing device that uses a special plastic to detect alpha particles from radon decay, typically used for long-term radon testing.
Continuous Radon Monitor
An electronic device that continuously measures radon levels in real-time, providing immediate results during radon testing.
Radon Resistant New Construction (RRNC)
Building techniques and features incorporated during new home construction designed to prevent radon entry and reduce mitigation costs.
Soil Gas
Air found in the spaces between soil particles. Radon-bearing soil gas is the primary source of radon entering homes through foundation gaps and cracks.
