Radon Mitigation And Reduction

What exactly is Radon?

Radon, known as Radon-222, is actually a radioactive gas released through the organic decay of thorium and uranium, that are common, naturally occurring elements identified in varying amounts in rock and soil. Typical pressure differences between the foundation and also the surrounding soil can produce a "vacuum" that will draw radon gas from the soil in to the foundation. Because of a number of elements which includes lack of air, it can not be diluted and may accumulate to significant levels.

Is It Hazardous?

Yes, it really is risky. Odorless, colorless, tasteless - and present in greater than 6,000,000 (6 million) houses inside the US - it can't be detected with human senses. In accordance with the EPA, no radon level is considered "safe". The risk of developing lung cancer is straight proportional to the levels and duration of exposure to radon: the greater the radon concentration, the larger the lung cancer threat. In case your Radon is in between two pCi/L and 4 pCi/L you'll want to contemplate fixing your home. If your radon is above four pCi/L, it can be essential you repair your home. In case your residence has below 2 pCi/L, you'll find still preventative measures you are able to take to safeguard your home.

Sources of Radon

How, and how much, it enters a home is dependent upon the design, building, condition, and ventilation from the house. Radon levels are normally greater in basements and rooms that happen to be in contact with soil, on the other hand radon can enter any residence via concrete floors and walls, floor drains, sump pumps, building joints, and tiny cracks or pores in hollow-block walls. Other sources contain:

• Cracks in concrete slabs • Spaces behind brick veneer walls that rest on uncapped hollow-brick foundation • Pores and cracks in concrete blocks • Floor-wall joints • Exposed soil, as inside a sump • Weeping (drain) tile, if drained to open sump • Mortar joints • Loose fitting pipe penetrations • Open tops of block walls • Building supplies for instance some rocks • Water (from some wells)

Radon Mitigation and Reduction

How much Radon is in your basement will likely be the main issue for figuring out which Radon method is finest for you. For basements with low levels of Radon, repairing cracks and using a penetrating sealer could be enough to decrease, or get rid of, Radon. For basements with high levels of Radon, a mitigation system may have to become installed in conjunction with repairing cracks and applying a penetrating sealer.
