How Does a Radon Mitigation System Work?



While most people never think twice about radon, it is a serious danger to households across the nation. For the fortunate few who do decide to test and discover that their air or water contains high amounts of this radioactive gas, don’t stress. There are mitigation experts who can fix the problem permanently for about the same cost as other typical household repairs.

Cleaning Up the Air

If the radon test came back showing elevated gas levels, the first thing to consider is how to rid the air of this health hazard. For those who live in an existing home, don’t worry; we don’t have to knock down walls, rip up sod, or even put a hole in the roof. Mitigating radon gas from household air is a fairly innocuous task that leaves no scar on landscaping or the home itself. In order to mitigate radon, we simply put a pipe below the home’s foundation, attach that pipe to another which runs up along the outside wall of the home, and attach that to a fan which draws the radon up, over, and out of the home.

Why It Works

The above technique is referred to as sub-slab depressurization and is extremely effective for radon mitigation in a home’s air because almost all radon seeps in from the foundation. Radon gas comes from the decay of naturally occurring radioactive elements found in the ground. By pulling this dangerous gas out from under the foundation, we can prevent it from accumulating in the home. Once installed, we leave this mitigation system in place and leave instructions with the homeowners. Cleaning the gas out from underneath a home is an ongoing project since, without mitigation efforts, it will just start accumulating to dangerous levels again.

Cleaning Up Water

Another place where people may find radon is in their water. As most people know, it is possible to mix carbon dioxide with water so as to produce “soda water.” Like carbon dioxide, radon is a gas. Just like carbon dioxide, radon can mix with a home’s water supply. There are two ways to perform water radon mitigation in NH: aerate or filter. The aeration technique works by mixing large amounts of clean air with the home’s water supply, thereby displacing the radon, and then flushing the newly cleaned water through the home’s plumbing system. Filtration usually employs the use of a carbon filter to grab the radon gas particles and remove them from the water.
