Log on to the Internet to locate contact information for your state's radon office. Each state has an office that assists homeowners in radon detection in addition to constantly monitoring state radon levels. The EPA website explains that state offices can provide homeowners with free or inexpensive home radon test kits and provides information on how to contact them.
Purchase or obtain a home radon test kit. The time it takes to conduct the test can vary, but all doors and windows in the home should remain closed 12 hours before testing begins and not be left open for extended periods during testing. The EPA website explains that the test should be conducted in the lowest level of the home, preferably a basement.
Mail the test to the laboratory that is designated in the test packet. Once the test is sent in for analysis, results should be available within a few weeks. The EPA website explains that a radon level of 4 picocuries per liter or higher must be professionally addressed, while levels near 4 pCi/L are still a health risk.
Seek professional assistance to obtain a radon reduction system that can effectively eliminate radon in a home. The Radon Man website explains that reduction techniques can include soil suction and sealing foundation or basement cracks. The first technique removes radon from the area. The second technique is a preventive measure to stop radon's entry into the home. Additional tests can be performed to locate the exact point of radon entry.
