http://SwatRadonTeam.com | The presence of radon in homes and commercial buildings needs to be handled quickly with radon mitigation. Radon is a naturally occurring odorless, tasteless radioactive gas that is produced from the decay of uranium found in nearly all soil. While outdoor exposure poses very little risk to humans, it can accumulate to dangerous levels indoors. Radon exposure is one of the leading causes of lung cancer and has no immediate symptoms from exposure. Because it is undetectable without special testing, many commercial buildings contain unhealthy levels of radon gas, necessitating the use of radon mitigation systems. Elevated radon levels have been found in commercial and residential buildings across the country and no area is free from risk of exposure. A majority of radon that enters buildings originates in the soil and seeps into living and working spaces through cracks and holes in the foundation. Once inside, radon can build up, causing dangerous levels for humans, which requires radon mitigation to abate the gas. The existence of radon gas in commercial buildings poses the greatest health risks of all building types, as a higher concentration people are affected than in a single family home. Radon exposure poses a great health risk and should be handled quickly by radon mitigation specialists. According to the U.S. Environmental Protection Agency, a test result of 4.0 pCi/L or higher designates an actionable level that requires some form of radon mitigation. Radon mitigation applications are often complex and require an in-depth knowledge of construction and building techniques.
While similar principles apply as in residential settings, radon mitigation systems must deal with more complicated HVAC, multiple levels, larger inhabitable space, and varying types of building construction. It is important to ensure the right methods, equipment, and tools are used for radon mitigation by using an appropriately credentialed contractor. An improperly installed radon mitigation system can actually make radon levels worse. HVAC systems often create zones of negative pressure in comparison to the soil, which effectively mines radon from the soil and distributes it quite effectively throughout the building. Radon mitigation seeks to equalize this pressure and restore healthy air quality back to the building. Sealing foundations has some effect for radon mitigation, but is not considered a permanent solution. One method of radon mitigation that has consistently had effective results is changing the pressure of the ground rooms that touch the building’s foundation to more positive in relationship to the soil beneath the foundation slab. This type of radon mitigation is accomplished in two ways: increasing the amount of air entering the room, or removing air from the soil through a process called sub-slab depressurization. Before implementing the radon mitigation system of sub-slab depressurization, testing is conducted by a radon mitigation specialist. Finished depressurization of the radon mitigation system is simulated to determine the number suction holes necessary, and the type of radon mitigation fans and piping the must be used. Once testing is completed, radon mitigation contractors can begin work immediately to make the commercial building safe again for workers and residents.
