Radon screening:

Radon definition:  Radon is a naturally occurring radioactive gas from decaying Uranium.  It is considered a "class A" carcinogen, and is soon to pass smoking for the number one position for causing lung cancer.  It claims 21,000 death victims from lung cancer per year.

Radon penetration:  is caused several natural ways on slab and especially basement homes.  The natural and mechanical negative pressure at the lower levels of the house causes the radon gas to penetrate the home.  Also, unfortunately, radioactive particles are located in the poured concrete of many homes rendering even high rise condos at risk.

Radon screening: requires a 48 hour residing time at the property; then a 24 hour analysis time to receive the results of the tests.  A $150 fee for testing includes either dropping the test canisters or picking up the test canisters at the time of the main home inspection.  Additional fees will be added if the testing is done apart from the home inspection.

Radon mitigation:  consists of an exhaust system creating a negative pressure under the slab directing air and gasses from under the slab of the basement area through the center of the house to discharge above the roof area.  Radon mitigation is suggested by the EPA when the levels of radon exceed 4.0 pCi/l (picocuries/liter).

Radon Results:  Radon varies with intensity over time.  Testing one time may not respond with true radon levels of residents exposure.  Radon testing equipment for long duration samples are available; inquire with Calibre Home inspections for correct type of testing equipment.  Elevated levels of radon have been noted just north of Buford Georgia and around the Stone Mountain area.
