Radon Testing and Inspections

Radon is a radioactive gas that is colorless, odorless, and tasteless. It comes from the natural breakdown of uranium in soil, rock and water and gets into the air you breathe. Radon typically moves up through the ground to the air and into your home through cracks and holes in the foundation or through well water. The home then traps radon inside.

How radon infiltrates a home

Radon is the second leading cause of lung cancer deaths in the US, claiming about 20,000 lives annually. Radon has been found in elevated levels in homes in every state. No area of the country is free from risk. Even two homes right next to each other can have vastly different radon levels. The only way to know if your home is under the EPA action level of 4 pCi/L is to test! The U.S. Surgeon General recommends that all homes be tested for radon. Testing is easy and if the house has a radon problem, steps can be taken to fix it to protect your family. Radon presents a serious health risk, but it can be controlled easily and cost-effectively.

Why test for radon?

Unless you test for radon there is no way of telling how much is present. Radon gas decays into radioactive particles that can get trapped in your lungs when you breathe.

Any home can have a problem… old, new, well-sealed, drafty and a home with and without a basement. Local geology, construction materials and how the home was built are among the factors that can effect radon levels in homes. The EPA recommends testing for radon in all homes below the third floor. On average, one out of every fifteen US homes has a problem. The only way to know whether or not your home has a radon problem is to test for it.

How much radon is too much?

The EPA indicates that 4pCi/L or higher concentrations of radon are considered above safe level.

Do I still need to test if there is no basement?

Yes, most indoor radon comes from naturally occurring radon in the soil but high indoor levels are more likely to exist below the third floor. The EPA recommends testing all homes.

Where is the radon testing performed?

On the lowest level of the home that is suitable for occupancy. This means the lowest level that you are going to use as living space which is finished or does not require renovations prior to use. A qualified radon tester will make some of these decisions.

Our radon level exceeds 4pCi/L; now what?

The type of house and the foundation design affects the kind of radon reduction system that will work best. In many cases simple systems using underground pipes and an exhaust fan can be used and do not require major changes to your home. Sealing cracks in the floors and walls will limit the flow or radon into your home and reduces the loss of conditioned air.

What is Continuous Radon Monitoring?

Active monitors – the type used by Camelot Home Inspections – are designed to provide data on the range of variation within the test period, detect and deter interference. This type of monitor requires operation by a trained tester who participates in the national qualification program for radon professions.

How much does it cost to reduce radon levels?

The average cost to install radon-resistant features in a existing home is $500 to $2500 depending on the size and design of the house and which radon reduction methods are needed. The average cost is $1200. Lowering high radon levels requires technical knowledge and special skills so it is best to use a contractor who is trained to fix radon problems.

Testing before selling?

Where radon problems have been fixed, home sales have not been blocked or frustrated. In fact, the added protection is sometimes a good selling point.
