Somewhere between $20 and $125.
The $20 test is a DIY at-home version consisting of two charcoal canisters, which you hang side-by-side from the ceiling of the lowest livable space in your home and leave for one year.
Then, you send it to the lab, and they will email you the results.
$125 is for an electronic 48-hour radon test for real estate transactions. They’re equipped with internal sensors that prevent tampering by measuring conditions like:
- Temperature
- Humidity
- Barometric Pressure
- Tilt
If the monitor is tampered with, the results become null and void, and the area must be re-tested.
