How to access your long-term radon test kit results:

If you have completed a long-term test, you can access your results by registering your test kit and then going to www.radonline.com.

To register your kit, you will need your device's serial number as well as the unique commission number and password included on the instruction sheet with your test kit.

If you no longer have this instruction sheet, you can obtain a new commission number and password by contacting Radonova, Inc. directly at (331) 814-2200.
