Radon Testing Fundamentals: Things You Should Know
Posted on: 18 August 2021
Radon is a naturally occurring radioactive gas. When rocks and soil break down, the uranium present in those elements will break down as well, creating radon gas. That gas works its way out of the soil and can pass into homes through all sorts of vulnerabilities in the basement or foundation. Since prolonged or significant exposure to radon can be carcinogenic, it's important that you test for its presence regularly in your home. However, common mistakes can lead to inaccurate test results. Here's a look at some of the things to keep in mind when you're testing your home's radon levels.
Position The Testing Unit Properly
In most cases, radon testing is done by professionals, so you can be confident that your test unit is positioned correctly. If you're doing the tests yourself, though, you need to be attentive to how and where you place the test unit.
If you want the most accurate results, your test unit should be placed in an area with airflow around it, so it should be free of boxes, structural posts, appliances, or any other obstructions.
It should also be placed a foot or more away from all of the walls in the testing area. Keep the testing unit free of any kind of drafts or direct sun exposure, and make sure that it's at least a couple of feet off the ground.
Don't Touch The Testing Unit
Once your radon testing unit has been installed, you need to leave it where it is for the duration of the test. Moving the testing device could disrupt the readings and result in an inaccurate final assessment. Make sure that, wherever you place it, it can stay undisturbed for the entirety of the testing time.
Keep Your Home Closed Up
In order for a radon test to be accurate, you need to eliminate any incoming fresh air or drafts from your home. That means closing all of your windows and doors and keeping them closed throughout the testing period. Your testing technician will tell you that you can go in and out one door, but choose one and only leave it open for as long as absolutely necessary when you come in and out. This keeps fresh air from diluting the test results.
Choose The Right Time For Testing
If you want to get the most accurate results for your radon test, you need to choose the right time of year to conduct the test. In many cases, spring and summer are not the best times for radon testing. Between the rain and humidity disrupting the test results and the open doors and windows that often accompany these seasons, you're likely to get an inaccurate test if you do it during these seasons.
Instead, opt for a late fall or winter radon test. Your home will already be closed up for the cold weather, and it will give you an idea of the highest possible levels of radon in your home.
