I used a radon self-test kit and the reading was high. What do I do now?
Test again. If you purchased your radon self-test kit at your local hardware store, chances are it was stored near other home safety devices such as smoke- and carbon monoxide detectors. These detectors emit a small amount of particles that cause radon gas and if stored near one another for a long period of time, could have an adverse effect on the home test kit’s reading.
If a second test reveals a high level of radon, contact a professional to ask about measures to vent the radon from your home.
