The first step in mitigation is testing to see if the indoor-air and/or domestic water radon concentrations should be reduced. Radon mitigation training in Florida does not include problems associated with mechanical ventilation systems, such as high indoor humidity, mold, moldy odors, property damage or health consequences of human occupation in high humidity of moldy environments[citation needed]. Occasionally, passive sumps without a fan may reduce radon levels. This brochure is for people who tested their home indoor air for radon and have elevated radon levels of 4 picocuries per liter (pCi/L) or higher. The earth floor in crawl spaces should be covered with a high-density plastic sheet, then use a vent pipe and fan to draw the radon from under the sheet and vent it outside.

If the presence of radon is detected in a property, and the levels are higher than what is considered safe, then radon mitigation efforts will be recommended. Radon contractors use other methods that may also work in your home. The accuracy of the residential radon test depends upon the lack of ventilation in the house when the sample is being obtained.
