Radon Detection and Reduction questions, answered by experts

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

Results from radon testing usually take a week to process after the test period ends, with expedited services sometimes available for urgent cases.

Yes, DIY kits are available, but professional testing provides more accurate results and comprehensive reports.

A radon test has no effect on humans—only the radon in the air does. The test does not redistribute the radon that is already present so yes, it’s safe to be around the testing kit even if it isn’t safe to be in the room itself. The test absorbs and measures the radon, but doesn't absorb enough of it to make the room any safer.
