Testing for Radon
There are two types of devices used for short term testing. Active devices are operated by trained testers like us and can monitor data over the entire test period. Passive devices, like the one used in the video below, use charcoal to trap radon. The tests are sent to a laboratory for analysis. Passive testing can run as little as $7.95 with a home radon test kit. Ordering information can be found here with a discount for Minnesota residents. Here is a short video on how easy it is to test your home for radon.
Here is a map of Radon zones from the EPA. Most of the southern half of Minnesota is in Zone 1. Zone 1 counties have a predicted average indoor radon screening level greater than 4 pCi/L (picocuries per liter) (red zones). The northern half is in Zone 2. Zone 2 counties have a predicted average indoor radon screening level between 2 and 4 pCi/L (orange zones).
What to do next
The EPA recommends if you have a result of 4 pCi/L or higher a follow up test to confirm whether mitigation is recommended. If levels are 10 pCi/L or higher a second short term test should be administered by a professional as soon as possible. Contact us about either testing or mitigation or both if you fear you have high levels of radon.
