Radon gas is odorless, colorless and radioactive. It comes from the breakdown of uranium, which is present in the soil, water and natural gas in many areas of the country. According to the EPA, radon gas is the second leading cause of lung cancer. Due to the health risks that exposure to radon can cause, all homes should be tested, and if the gas is found, it needs to be removed. Before radon testing and mitigation, there are a few things you should know about this serious health hazard.

The Average Cost for Radon Mitigation
The first step in radon mitigation is testing for the presence of the gas. There are different types of radon tests. Only a licensed radon tester can perform such a test, and a homeowner can expect to pay around $200. The average cost of testing and installation of a radon mitigation system is $758, explains the Home Advisor website. Most homeowners spent between $644 and $872 for radon testing and mitigation of the gas.
How Radon Enters a Home
Radon gas can get into a home through water and natural gas supply lines. Most commonly, radon gas enters a home through the foundation. The foundation is in direct contact with the soil. The gas can seep into the home through openings like drains or a sump pump. It can also get in through small cracks in the foundation footer or walls.
Why Radon Needs to Be Removed
The radioactivity of radon gas can trigger the progression of cancer. After years of exposure to radon gas, lung cancer can develop. In people who smoke and are also exposed to radon gas, the risk of lung cancer is much higher than in those who only smoke.
Factors to Consider When Testing for or Removing Radon Gas
There are several types of radon mitigation systems, including suction, sub-slab, ventilation and sealing. In most cases, a combination of these methods will be used to prevent the infiltration of radon gas into the home. Sealing the foundation prevents radon from getting in while the ventilation, suction, and sub-slab depressurization removes the gas that does get in and ventilates it to the outdoor environment.
