Radon Tesing Checklist

For reliable test results, follow this Radon Testing Checklist carefully. Testing for radon is not complicated. Improper testing may yield inaccurate results and require another test. Disturbing or interfering with the test device, or with closed-house conditions, may invalidate the test results and is illegal in some states. If the seller or qualified tester cannot confirm that all items have been completed, take another test.

Before Conducting a Radon Test:


Notify the occupants of the importance of proper testing conditions. Give the occupants written instructions or a copy of this Guide and explain the directions carefully.


When doing a short-term test ranging from 2-4 days, it is important to maintain closed-house conditions for at least 12 hours before the beginning of the test and during the entire test period.


When doing a short-term test ranging from 4-7 days, EPA recommends that closed-house conditions be maintained.


If you conduct the test yourself, use a qualified radon measurement device and follow the laboratory's instructions. Your state or county extension office may be able to provide you with a list of do-it-yourself test devices available from qualified laboratories.


If you hire someone to do the test, hire only a qualified individual. Some states issue photo identification (ID) cards; ask to see it. The tester's ID number, if available, should be included or noted in the test report. NEHA-NRPP provides laminated ID cards to its certified individuals.


The test should include method(s) to prevent or detect interference with testing conditions or with the testing device itself.


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.

Closed-house conditions means keeping all windows closed, keeping doors closed except for normal entry and exit, and not operating fans or other machines which bring in air from outside. Fans that are part of a radon-reduction system or small exhaust fans operating for only short periods of time may run during the test.


During a Radon Test:


Maintain closed-house conditions during he entire time of a short term test, especially for tests shorter than one week in length.


Operate the home's heating and cooling systems normally during the test. For tests lasting less than one week, operate only air-conditioning units which recirculate interior air.


Do not disturb the test device at any time during the test.


If a radon-reduction system is in place, make sure the system is working properly and will be in operation during the entire radon test.

After a Radon Test:


If you conduct the test yourself, be sure to promptly return the test device to the laboratory. Be sure to complete the required information, including start and stop times, test location, etc.


If an elevated level is found, fix the home. Contact a qualified radon-reduction contractor about lowering the radon level. EPA recommends that you fix the home when the radon level is 4 pCi/L or more.


Be sure that you or the radon tester can demonstrate or provide information to ensure that the testing conditions were not violated during the testing period.

The EPA’s Consumer’s Guide to Radon Reduction
(www.epa.gov/radon/pubs/consguid.html) provides the following guidelines for radon mitigation:

Radon mitigation systems reduces moisture.

Radon Mitigation systems, properly installed, will also have the added benefit of reducing the moisture in a basement. Some to the point of not having to use a dehumidifier at all, saving on electricity & having to empty the unit.
The radon system removes the moist air under the slab & the vents it above the roof line into air. No more damp musty basements.

Radon is a cancer-causing, radioactive gas.
You can’t see radon. And you can’t smell it or taste it. But it may be a problem in your home.
Radon is estimated to cause many thousands of deaths each year. That’s because when you breathe air containing radon, you can get lung cancer. In fact, the Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today. Only smoking causes more lung cancer deaths. If you smoke and your home has high radon levels, your risk of lung cancer is especially high.
Radon can be found all over the U.S.
Radon comes from the natural (radioactive) breakdown of uranium in soil, rock and water and gets into the air you breathe. Radon can be found all over the U.S. It can get into any type of building—homes, offices, and schools—and result in a high indoor radon level. But you and your family are most likely to get your great­est exposure at home, where you spend most of your time.
Testing is the only way to know if you and your family are at risk from radon. EPA and the Surgeon General recommend testing all homes below the third floor for radon. EPA also recommends testing in schools.
Testing is inexpensive and easy—it should only take a few minutes of your time. Millions of Americans have already tested their homes for radon.
Radon reduction systems work and they are not too costly. Some radon reduction systems can reduce radon levels in your home by up to 99%. Even very high levels can be reduced to acceptable levels.
Radon-resistant construction techniques can be effective in preventing radon entry. When installed properly and completely, these simple and inexpensive techniques can help reduce indoor radon levels in homes. In addition, installing them at the time of construction makes it easier and less expensive to reduce radon levels further if these passive techniques don’t reduce radon levels to below 4 pCi/L. Every new home should be tested after occupancy, even if it was built radon-resistant. If radon levels are still in excess of 4 pCi/L, the passive system should be activated by having a qualified mitigator install a vent fan.
