How to Prepare for a Radon Test

Raise Your Radon IQ

Closed House Conditions

First, congratulations on taking the first step towards making sure your home’s radon levels are in an acceptable range. Your upcoming Radon Test will require you to abide by the EPA testing standard called “Closed House Conditions.”

In this article, we will cover what Closed House Conditions mean and how Radon Testing might impact you and your family.

Steps to Take Before & During a Radon Test

The following steps need to be taken to ensure a smooth testing process with accurate results:
  • Notify the occupants of the importance of proper testing conditions. If possible, share this guide and explain the directions carefully.
  • Conduct the radon test for a minimum of 48 hours.
  • Maintain closed-house conditions (keeping doors and windows closed) for a minimum of 12 hours before the 48-hour test begins and throughout the duration of the test.
  • If the house has an active radon-reduction system, make sure the vent fan is operating properly. If the fan is not operating properly, have it (or ask to have it) repaired and then test.
  • Operate heating and cooling systems normally during the test. For tests lasting less than one week, operate only air-conditioning units which re-circulate interior air.
  • Do not disturb the test devices at any time during the test.
After testing, the devices will be picked up and data will be recorded, with results delivered within 1 business day via email.
