Techniques in Lowering Radon Gas Levels in Your Home

Radon is a radioactive gas that is considered to be a health hazard. It comes from natural sources and can build up inside buildings and houses, particularly in small spaces like basements and attics. This is the reason why it is important to have a property inspected for radon gas before buying it among the available Arlington homes for sale.

Radon levels can be lowered by mitigation, the process of moderating or making it less dangerous. Some of the techniques prevent this radioactive gas from going into the house, while others lessen the levels after it has entered. As recommended by the U.S. Environmental Protection Agency (EPA), mitigation methods must be used if the level of radon inside the home has reached over 4 pCi/L or 0.02 WL (working levels).

Radon Mitigation Techniques

Some of the mitigation methods commonly used to lower radon levels are the following:

1. Soil Suction – This is done by drawing radon gas from under the house and venting it away by the use of pipes.

2. Sealing Openings and Cracks – Usually, this method alone can’t lower the levels of radon; sealing simply limits the flow of the gas inside a house and reduces the loss of conditioned air. This is used to make other types of techniques more efficient.

3. House Pressurization – This utilizes a fan to make pressure differences that aid in preventing radon from going inside the home.

4. Heat Recovery Ventilator (HRV) – This system is used to increase ventilation by utilizing the cooled/heated air being used to cool/warm the air coming inside. An HRV is most efficient when used to circulate air only in the basement. Cooling and heating costs are likely to rise if this is used.

If it was detected that the source of radon gas in your home is the water supply, there are some ways to fix it. Some treatments remove the gas from the water before it even enters the home by using aeration devices or charcoal filters. Other methods use point-of-use devices that eliminate radon at the faucet, so it will not be ingested. These tools do not reduce the gas in unfiltered faucets, like showers, in laundry areas, and tubs. This may make the radon levels remain high in the air.
