Radon is an odorless, colorless radioactive gas that can enter a home. Most of Colorado is considered a high risk area for radon, which occurs from the natural radium and uranium found in Colorado soil. Estimates of lung cancer deaths associated with Radon range as 21,000 in the United States. The combination of high concentrations of Radon coupled with tobacco smoking dramatically increases the risk of lung cancer. In the United States, the Environmental Protection Agency (EPA) has set a measurement of 4 picocuries per liter (4 pCi/l) as the maximum amount that does not pose a health hazard. Radon amounts above 4.0 pCi/l pose a health risk, and mitigation measures are advised. The higher the amount of Radon present, the greater the risk to dwelling occupants.
Home buyers have the legal opportunity to have testing performed to determine the presence of Radon and should have this test performed during the contractual inspection period. Most certified home inspectors can perform radon gas testing, using sophisticated electronic measuring devices. The cost of testing is usually $75 -$150 dollars, including a written report.
If your home tests higher then 4.0 pCi/l, mitigation should be performed, and can be relatively simple in most homes. An EPA certified mitigation contractor can install a sub-slab ventilation system, which equalizes the pressure in the house, preventing Radon gas buildup. At times, more complex measures must be taken, but seldom is the cost to mitigate prohibitive. Though the cost to mitigate can be a negotiable item, as a home seller having the migration completed can only greatly contribute to the sale of your home as most buyers will not buy a home with high levels of Radon.
