What the zone means for a Martinsville city home
Zone 1 means EPA predicted an average indoor screening level above 4 pCi/L for Martinsville city as a whole, the level at which EPA says to fix a home. High readings are common here, so a test is especially worthwhile, and new homes in Martinsville city are good candidates for radon-resistant construction.
A short-term test kit costs little and takes two to seven days. If your result is 4 pCi/L or higher, EPA recommends a follow-up test and, if it is confirmed, a mitigation system, which typically uses a pipe and fan to pull soil gas from under the foundation and vent it above the roof. Check a result with the level calculator and plan your next step with the follow-up planner.
