Of the more than 4000 chemicals present in cigarette smoke, more than 60 have been identified as cancer causing chemicals, 11 of which are known to cause cancer in humans and 8 that have been associated with causing cancer in humans.
1 Ground water wells can also be tested for radon, then, if needed, can get a water radon mitigation system installed. 2  Installing a water radon mitigation system runs from $1,000-$4,500, and maintenance runs $0 to $150 annually. 3  To find out about radon content in a city water system, call the local water provider. It's wise to retest a home's radon level every year or two after a mitigation system is installed. 2  Most radon mitigation systems include a fan, which will need to be replaced about every 5 years. 3  Expect to pay $250-$300 to have this necessary maintenance done.
If this is the case, the situation can be remedied by a radon mitigation system, which can cost anywhere from approximately $1,000 â $2,000 (at least this has been my experience) depending of the type of system and the specific characteristics of the home. The cost of the actual radon test itself is not expensive. Some home inspectors will provide an AccuStar kit to test the radon for which they charge their clients $65âish (give or take), while others bring a machine for which they charge $125âish (give or take).
