How do you skew a radon test?
Rain during the test period can skew test results—sometimes quite dramatically. This is because rain drives radon out of the ground, which results in a high radon level reading.
How do you lower radon levels before a test?
In some cases, radon levels can be lowered by ventilating the crawlspace passively, or actively, with the use of a fan. Crawlspace ventilation may lower indoor radon levels both by reducing the home's suction on the soil and by diluting the radon beneath the home.
What should you not do during a radon test?
Turn off all air moving devices during the test. This would include ceiling fans, dehumidifiers, regular fans, HEPA or any other kind of filtering device that moves air. Do not operate fireplaces or heating stoves during the test unless they are your main source of heat.
