Q: What is Radon?
A: Radon is an invisible, odorless radioactive gas created from natural deposits of uranium in the soil. Radon gas can be drawn into a building and accumulate to concentrations that may cause a health concern. Finding high levels of radon in a home has nothing to do with the age, quality, or upkeep of the home.
Q: How do I know if a home has elevated levels of radon?
A: The only way to know if a home has elevated levels of radon is to have the house tested. The US EPA has set the action level at 4.0 picocuries (pCi/L). If test results confirm levels higher than 4.0 picocuries you should consider taking steps to reduce the radon levels. Central Wisconsin and especially Marathon County is high in radon. Every home may test differently depending on home design and the source of excavation materials.
Q: Who Do I Call to Get a System Installed?
A: Use only certified radon mitigation professionals to ensure that your system is installed properly and meets all EPA code requirements. A trained mitigator will test to ensure a sub-slab depressurization system will reduce radon levels to below 4 pCi/L and will properly size the fan and seal required areas so that interior conditioned air is not lost. A trained mitigator will also ensure that the system is aesthetically pleasing.
Q: What are the Health Risks?
A: Radon is the number one cause of lung cancer among non-smokers, according to EPA estimates. Overall, radon is the second leading cause of lung cancer. Radon is responsible for about 21,000 lung cancer deaths every year. About 2,900 of these deaths occur among people who have never smoked.

"Indoor radon is the second leading cause of lung cancer in the United States and breathing it over prolonged periods can present a significant health risk to families all over the country. It is important to know that this threat is completely preventable. Radon can be detected with a simple test and fixed through well-established venting techniques."
