What are the solutions for Radon Gas?
Airborne Radon Reduction
Most airborne reduction systems require the mitigator to follow three stages to effectively reduce radon levels: diagnostic evaluation, sealing of the foundation or crawl space, and installation of the system. The radon contractor will use their knowledge and skills to design the most cost-effective and correct system for your home.
Airborne radon systems work by altering air pressure beneath your home and drawing out radon gas through one or more pipes to the exterior of the home with a specially designed radon fan. The systems are usually routed through the interior of the home, through the garage, or to the exterior, often venting above the roofline.
The most popular type of installed system was formerly called sub-slab depressurization or SSD. It has been renamed to active soil depressurization or ASD. Another emerging method involves the installation of a heat recovery ventilator designed to ensure the optimal indoor air quality.
Waterborne Radon Reduction
Experienced mitigators will require the following for waterborne radon reduction prior to recommending the best system and location: assessment of the waterborne radon level; complete water analysis, identifying the presence of other contaminants; and measurement of the water flow rate. Your preferences should be taken into consideration along with the plumbing, electrical, and venting requirements.
The two most common types of waterborne radon reduction systems are aeration and granular-activated carbon or GAC. The key factor in selecting the most appropriate system is the radon level.
The EPA does not recommend GAC for radon levels above 5,000 pCi/L. The aeration method is rated by the EPA as the best available technology or BAT. Other methods, such as GAC, may pose the threat of waste buildup. The design of aeration systems allows radon gas isolation from the well water, venting the contaminants safely above the roofline.
GAC systems require more meticulous maintenance, or problems with radioactivity or ineffectiveness may result. GAC systems use one, two, or three carbon beds or tanks where the radon is adsorbed. If the tanks are left in place too long, the carbon becomes ineffective and possibly contaminated.
When properly installed and serviced, they are effective. Therefore, it is necessary to service GAC systems by ensuring the tanks are changed in a timely manner. Usually annual replacement suffices, but may differ according to the well water quality and levels of contamination.
Radon Mitigation Services
Considering the serious health risks and difficulty in detecting radon gas, it is highly recommended that homeowners and business owners consult the services of a certified radon contractor/mitigator when radon levels have been confirmed to be elevated.
These professionals have been trained, tested, and certified in effective radon concern resolution according to the standards set by the National Radon Proficiency Program or the National Radon Safety Board. They will address radon concerns and most will provide a free estimate for the design and installation of an effective radon reduction system for your home.
Time for Action
Do not delay making a decision about assessing radon risk in your home You and your loved ones cannot afford to take any chances in ignoring the recognized health risks of radon gas!
