This month is National Radon Action Month. At Image Design we are alway watching out for you and your loved ones. Did you know that Radon is actually deadlier than carbon monoxide. List below are some interesting fact you might not know.

  • Breathing home indoor radon causes nearly one hundred times more deaths each year than carbon monoxide poisoning.

  • Radon is the second leading cause of lung cancer.

  • Some 20,000 people will die this year due to breathing too much radon without even knowing it.

  • Radon is estimated to be a health risk in as many as one in fifteen homes throughout the country.
  • According to Governor Granholm's Proclamation, one in eight homes in Michigan (EPA's map of Michigan radon zones) have elevated levels of radon

Radon is a colorless, odorless, tasteless, invisible radioactive gas that seeps into homes undetected through cracks or openings in the foundation, floor or walls, and can reach harmful levels if trapped indoors. It travels up from underground sources and uranium in the earth’s crust. And can be found in all the county in the state of Michigan see our Radon Map for our state below.

My goal this month is to raise your awareness of Radon and to teach you how we at Image Design take extra steps in our plans to reduce your risks of Radon.

At Image Design we include all these Radon prevention techniques in our sets of plans:

  1. Gas Permeable Layer. This layer is placed beneath the slab or flooring system to allow the soil gas to move freely underneath the house. In many cases, the material used is a 4-inch layer of clean gravel.

  2. Plastic Sheeting. Plastic sheeting is placed on top of the gas permeable layer and under the slab to help prevent the soil gas from entering the home. In crawlspaces, the sheeting is placed over the crawlspace floor.

  3. Sealing and Caulking. All openings in the concrete foundation floor are sealed to reduce soil gas entry into the home.

  4. Vent Pipe. A 3- or 4-inch gas-tight or PVC pipe (commonly used for plumbing) runs from the gas permeable layer through the house to the roof to safely vent radon and other soil gases above the house this system is called Passive Radon Mitigation. If , after your house is complete, a test determines that levels are still too high, you may have to convert to an Active Radon Mitigation System by installing a fan than runs continuously which creates low pressure under the slab and increases the rate of gas evacuation..

  5. Junction Box. An electrical junction box is installed in case an electric venting fan is needed later.

As our nations builders start moving towards Green Building, builders shouldn’t forget that they can’t truly be green without being safe places for people to live.“It’s remarkably easy to protect our loved ones by testing for radon and building new homes with radon–resistant features that allow everyone to breathe freely and safely.” “It’s simple and cost–effective to build new homes with radon–resistant features“It makes sense to do it right from the start.” The radon threat is preventable with the simple steps above. When building new homes, builders can easily and economically include radon–resistant features during construction. The EPA also recommends that new built homes still be test for radon gas before they move in to make sure the radon–resistant features are working.
