Radon is a naturally occurring gas that comes from the decay of uranium found in most rocks and soil.
The only way to know the radon level in your home is to test with a radon kit. Available from UGA Extension, the kits can be ordered at www.ugaradon.org or by calling 1-800-ASK-UGA1.
On average, 1 in 15 homes will test at, or above, the acceptable level of radon gas, which is 4.0 picocuries per liter (4 pCi/L).
Because radon is heavier than air, radon levels in houses are the highest at ground level. Babies, young children and pets are at a higher risk since they are closer to the ground.
Testing should be done at the lowest livable area of homes, and the test kit should be placed at the breathing level of the shortest person in the family.
Radon testing should be done every two years, even with a radon reduction system in place, to ensure safety.
If test results come back at or above 4 pCi/L, radon mitigation is necessary. If the test results are between 2 and 4 pCi/L, there is still enough risk of excess exposure that radon mitigation is recommended.
Eliminating radon in homes is relatively simple. Radon mitigation companies can reduce radon levels by up to 99 percent. Visit www.ugaradon.org for a list of certified mitigators.
