What is Radon? Radon is a Cancer-Causing, Radioactive gas.

 

 You can’t see, smell, or taste radon. But it still may be a problem in your home. When you breathe air containing radon, you increase your risk of getting lung cancer. In fact, the surgeon General of the United States has warned that radon is the second leading cause of lung cancer in the United States today. If you smoke and your home has high radon levels, your risk of lung cancer is especially high.

 

In February 1998, the National Academy of Sciences (NAS) released a report on radon and lung cancer. NAS is an independent, non-governmental scientific organization.

The NAS estimates that radon causes between 15,000 and 22,000 lung cancer deaths each year in the United States and that 12 percent of all lung cancer deaths are linked to radon. The report concluded that after smoking, radon is the second leading cause of death due to lung cancer in the United States.

 

You Should Test for Radon

Testing is the only way to find out your home’s radon levels. EPA and the Surgeon General recommend testing all homes below the third floor level for radon.

 

You Can Fix a Radon Problem

EPA recommends that you take action to reduce your home’s indoor radon levels if your radon test is 4 pCi/L (picocuries per liter of air) or higher. It is better to correct a radon problem before placing your home on the market because than you have more times to address a radon problem.

 

If elevated levels are found during the real estate transaction, the buyer and sellers should discuss the timing and costs of radon reduction. The cost of making repairs to reduce radon levels depends on how your home was built and other factors. The average cost for a contractor to lower radon levels is a home range from $1200-$2800.

 

Types of Radon systems

A variety of methods can be used to reduce radon in homes. Sealing cracks and other openings in the foundation is a basic part of most approaches to radon reduction. EPA does not recommend the use of sealing alone to limit radon entry. Sealing alone has not been shown to lower radon levels significantly or consistently.

 

 

“Sub-slab depressurization-

Air is drawn from under the basement floor through a drilled hole. System is than vented to the exterior of the home with an inline fan mounted according to EPA protocols.

 

 

 

 

 

 

Sub-membrane depressurization-

When a crawl space is in the home it must be sealed with a puncture resistant membrane. The membrane than is sealed to the perimeter walls.

Under the sealed membrane a perforated pipe is installed and than venting of the area is run to the exterior of the home according to EPA protocols.

 

 

Sump Pump Depressurization

When a sump pit is in the home and has tile running into it from a perforated drain tile around the perimeter of the home, it is sealed and than used as a collection point. The pit is sealed with a radon resistant cover. Once sealed the pit area is than used to draw air from under the basement floor.

 

 

 

 

Three types of fan installation according to EPA protocols.

Garage fan installation

Exterior fan installation 

Attic fan installation

 

 The venting of the system is than to the exterior of the home on the outside, Garage, or Attic all according to EPA protocols either. No fans are to be mounted in the interior of the home.
