Testing for Radon

Testing for Radon

How to Test Your Home

It is simple to test. First, perform a short term test. The majority of short term tests take between 2-7 days. A Radon Testing in Terrell should take at least 48 hours.

Each of the lowest structural parts of your home should be tested for radon. A test should be done in each of the foundation areas if your home has more than one type. If a basement is part of a house, it should be tested if the basement is used for more than 7 hours per week. Install a radon detector above the crawl space if the home has one. Install a radon detector in every room if the cement floor is present. Avoid testing the laundry room, kitchen, and bathroom. All three types of foundations should be tested for Radon if a house is constructed.

Where to Find Test Kits

There are many types of short-term Radon detectors. There are many types of short-term radon detectors. Some come in bags, others in vials, and some come in round canisters. Here is a guide that covers several types of detectors. Follow the instructions on the packaging of the detector you select. You can purchase radon detectors at hardware stores and radon measurement labs. A licensed Illinois radon measurement professional is also available to test your home for radon.

Conducting the Test

These are only guidelines. Follow the instructions provided with your detector.

Twelve hours before and during the test

  • All windows and doors should be kept closed, except for normal entry or exit.
  • Fans or any other machine that brings in air from the outside should not be operated (except those that are part of a Radon Reduction System or small exhaust fans that only operate for a short time).

Where can I place the detector?

  • The detector will remain in its place
  • Three feet from the doors and windows that lead to the outside
  • From twenty inches to six feet above floor
  • All other objects are four inches away

How can I keep the detector from being placed?

The humidity can affect the performance of some detectors, so don’t put the radon detector in your bathroom, kitchen, laundry or laundry room. Avoid crawl spaces, cracks in walls, and areas near the sump pump. These places could lead to false highs. [See the image below.]

After the test is completed, make sure the time, start date, and stop date are all listed. Send the package with the detector and any other paperwork to the laboratory. Send the package to the laboratory for radon measurement. The results can usually be obtained within ten days to two week.

Interpreting the Results

If results are less than 4 pCi/L USEPA’s Action Level is used. No action is required. Retest in two years.

You may want to conduct a long-term test if your results are closer to 4 pCi/L to get a better idea of your year-round average.

Get Active If You See Results of 4 pCi/L Or More

If the results exceed 4 pCi/L, it is recommended to do a second test. Perform a short-term, or long-term test if the results are below 10 pCi/L. Perform another short-term test if the results are less than 10 pCi/L.

To reduce radon levels below 4 pCi/L, contact licensed mitigation contractors if the average or second results exceed 4 pCi/L.
