According to the IEMA, radon is defined as a radioactive element that is part of the radioactive decay chain of naturally occuring uranium in soil. There is no way to see the level of this element in your home without doing the radon test because we can not smell, see or taste it. In comparison to something like Carbon Monoxide it does not have immediate effects. However, its adverse effects occur if exposed to a high rate for long periods of time.
"The USEPA action level for radon is 4.0 picocuries per liter of air (pCi/L). The risk of developing lung cancer at 4.0 pCi/L is estimated at about 7 lung cancer deaths per 1000 persons. That is why USEPA and IEMA recommends reducing your radon level if the concentration is 4.0 pCi/L or more. "
If your home has not previously been tested for this gas, it is recommended. In fact, effective this year for the sale of homes a radon disclosure is required.
