#WhatisRadon and Why is it Dangerous?
Radon is a naturally occurring gas that forms from the decay of uranium in soil, rock, and water. It enters homes through cracks in the foundation, gaps in floors and walls, and openings around pipes and wires. Once inside, it can accumulate to dangerous levels, especially in areas with poor ventilation.
Exposure to high levels of radon over time increases the risk of lung cancer, particularly in non-smokers. The radioactive particles emitted by radon can damage lung tissue when inhaled, leading to mutations in cells and the development of cancerous growths.
The Importance of #RadonMitigation
Given its harmful effects, radon mitigation is crucial for protecting the health and safety of occupants in homes with elevated radon levels. Mitigation involves implementing measures to reduce radon concentrations to acceptable levels, typically below 4 picocuries per liter (pCi/L), as recommended by the Environmental Protection Agency (EPA).
#Radon Testing: The First Step
Before mitigation can begin, it's essential to conduct radon testing to determine the radon levels in your home. Short-term and long-term testing kits are available, allowing homeowners to assess radon levels over different periods. If high levels are detected, mitigation becomes necessary to reduce the health risks associated with radon exposure.
### Radon Mitigation Techniques
Several radon mitigation techniques are available, tailored to the unique characteristics of each home. Common methods include:
1. Sub-Slab Depressurization (SSD): This technique involves creating a vacuum beneath the home's foundation to prevent radon from entering. A system of pipes and fans is installed to draw radon-laden air from the soil and vent it safely outside.
2. Crawlspace Ventilation: For homes with crawlspaces, installing a ventilation system can help reduce radon levels by promoting air circulation and preventing radon buildup.
3. Sealing Cracks and Openings: By sealing cracks in floors, walls, and foundations, homeowners can minimize the entry points for radon, reducing its infiltration into living spaces.
4. Air Exchangers: Heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) exchange stale indoor air with fresh outdoor air while simultaneously removing radon gas.
Choosing a Qualified Radon Mitigation Professional
When selecting a radon mitigation contractor, it's essential to choose a qualified and certified professional with experience in radon mitigation. Look for contractors who are certified by the National Radon Proficiency Program (NRPP) or the American Association of Radon Scientists and Technologists (AARST) to ensure the effectiveness and safety of the mitigation system.
