Short Term Radon Test Kit
Charcoal Radon Test Kits
The quickest way to test for radon is with a short term charcoal radon testing kit. A short term radon test kit remains in your home for three to seven days. Because radon levels tend to vary from day to day and season to season, a short term radon gas test is less likely than a long term alpha track test kit to tell you your year-round average radon level. If you need results quickly, however, a short term test followed by a second short term test may be used to decide whether to fix your home.
These short term radon testing kits use a container that contains a quantity of granular activated charcoal. The charcoal absorbs the radon gas entering the canister from the surrounding air. At the end of the radon gas test period, the canister is sealed and sent to the laboratory in the pre-paid mailer for analysis.
DO NOT test areas of high humidity, such as bathrooms, kitchens, laundry rooms, closets, or damp basements. If you must test a damp or humid room (over 55% RH), then test only for the shortest recommended period. As an option, our Long Term Test Kits are not affected by humidity.
Note: If buying/selling a home, the EPA generally recommends taking two short term tests at the same time/same place to measure radon, taking the average of the two.

The EPA Recommends the Following Testing Steps:
The amount of radon in the air is measured in "picoCuries per liter of air," or "pCi/L." Sometimes test results are expressed in Working Levels (WL) rather than picoCuries per liter (pCi/L) (4 pCi/L equals to 0.016 WL).
Using a short term charcoal radon test kit, if your result is 4 pCi/L or higher (0.02 Working Levels [WL] or higher) take a follow-up test (Step 2) to be sure.
Follow-up with either a long term test or a second short term test:
The higher the result of your initial short term radon test kit, the more certain you can be that you should take another short term test rather than a long term follow-up test.
If your first short term test result is several times the action level - for example, about 10 pCi/L or higher - you should take a second short term test immediately.
If you followed up with a long term alpha track test kit: Fix your home if your long term test result is 4 pCi/L or more (0.02 Working Levels [WL] or higher).
If you followed up with a second short term radon test kit: The higher your short term results, the more certain you can be that you should fix your home. Consider fixing your home if the average of your first and second test is 4 pCi/L or higher (0.02 Working Levels [WL] or higher).
