Why Test Your Home For Radon?

Real estate transactions: If you have decided to conduct a radon home test as part of a real estate transaction, you may only have time for a short-term radon test.  Short-term radon tests provide a measure of the radon level in your home only during the brief test period.  The US EPA guidelines for radon tests of 2-7 days call for "closed house conditions" which necessitate sealing the house by closing all windows and using doors as little as possible.  The US EPA recommends running two short-term radon tests either side-by-side or sequentially.  Order Air Chek Short-Term Radon Test Kits

Verifying short-term radon results: Before spending money on a radon mitigation system, conduct a long-term test.  Radon levels vary in daily and seasonal cycles and in response to weather conditions and ventilation patterns.  Short-term radon tests may accurately report radon levels during the few days of their test period, but still not properly represent the long-term average radon level to which you are exposed.  The US EPA recommends a verification test with a long-term test kit if a short-term testing result showed radon levels higher than 4.0 pCi/L.

Long-term accuracy: Long-term radon tests provide you with the most accurate estimate of your health risk.  By averaging daily and seasonal radon fluctuations, testing for a full year will provide the most complete picture of the average radon level in your home.  RSSI alpha-track detectors can also provide excellent results in the 8-90 day test periods.  Homes do not need to be sealed for alpha-track tests, as is required for short-term tests.  Order Alpha Track Radon Gas Test Kits

Underlying geology: Radon levels fluctuate widely in regions of the country that have karst geology: fractured limestone, caves, or underground streams.  In a karst region or in a building over a mine, yearlong testing is recommended to account for these fluctuations.  If you have further questions, contact your state radon office.
