How do I test for radon?

The U.S. Surgeon General and EPA recommend that all homes be tested:

Option 1: The least costly method is to contact your county or city health department. They give away free test kits. After the test period you will need to send the test kit to a radon laboratory and wait for the results.  Note: Users should pay particular attention to the set up instructions because if done incorrectly another test may be required, plus the time for the results to be mailed and returned.  Please pay particular attention to placing the test kit instructions below.

Option 2: The second method is to go to your local building supply store, such as Lowe’s, Lumber King, etc., and purchase a short term test kit. This is acceptable to many; however, these are not free.  Again Note: Users should pay particular attention to the set up instructions because if done incorrectly, another test may be required taking more time for the results to be mailed and returned.  Please pay particular attention to placing the test kit instructions below.

Option 3: Use Advanced Radon Services, Inc.   We know how and where to properly set up the tester to give you true radon gas results. Our testing period is two days (minimum of 48 hours) and we have immediate results for you. However, we do cost more than the first two options.  Call us for pricing in your area.

Self Testing Instructions:  EPA Protocols
1. Do not conduct short-term tests lasting less than four days during severe storms or periods of high winds.

2. Close all windows and doors at least 12 hours before beginning the test and keep them closed except for normal entry and exit to the property.

3. Follow the testing instructions and record the start time and date.

4. Placing the test kit: Some test kit instructions suggest hanging the test from the hook provided at your normal breathing level.  Many people think this is at 5- 6 feet.  EPA protocol states:  Place the test device at least 20 inches above the floor in a location where it will not be disturbed and where it will be away from drafts, high heat, high humidity, and exterior walls.  Since radon is approximately 8 times heavier than air, doesn’t it make sense to place the test closer to the 20 inches above the floor number rather than 5-6 feet.
5. Leave the test kit in place for as long as the test instructions say; and once you have finished the test, record the stop time and date, reseal the package and return it immediately to the lab specified on the package for analysis. You should receive your test results within a few weeks.

If you need results quickly, you should find out how long results will take and, if necessary, request expedited service.
