Radon is estimated to cause many thousands of deaths each year. That's because when you breathe air containing radon, it can lead to lung cancer. The Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today, second only to smoking. It’s estimated there are more than 20,000 radon-related deaths each year in the United States. If you smoke and your home has high radon levels, your risk of lung cancer is especially high. (1)

You can't see radon, but it's not hard to find out if you have a radon problem in your home. All you need to do is test for radon.

The amount of radon in the air is measured in "picoCuries per liter of air," or "pCi/L.". There are many kinds of low-cost "do-it-yourself" radon test kits you can get through the mail and in hardware stores and other retail outlets. If you prefer, you can call the Radon Hotline at 1-800458-1158 and order the test canisters from the New York State Department of Health (DOH). If you explain that you are a day care provider, the DOH will send you a test canister for $5.50 (current price as of January 2015). This is a reduced price.

The quickest way to test is with short-term tests. Short-term tests remain in your home for two days to 90 days, depending on the device. "Charcoal canisters," "alpha track," "electret ion chamber," "continuous monitors," and "charcoal liquid scintillation" detectors are most commonly used for short-term testing. Because radon levels tend to vary from day to day and season to season, a short-term test is less likely than a long-term test 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.

How to Test for Radon in Your Family or Group Family Day Care Program:

Testing is easy and should only take a few minutes to set up.

What Your Test Results Mean

Test your child day care space now and save your results. Results must be reported to OCFS if your home is located in any one of the listed New York State radon zones. If testing reveals high radon levels (4.0 pCi/L or above), remediation is required.

The average indoor radon level is estimated to be about 1.3 pCi/L, and about 0.4 pCi/L of radon is normally found in the outside air. The U.S. Congress has set a long-term goal that indoor radon levels be no more than outdoor levels. While this goal is not yet technologically achievable in all cases, most homes today can be reduced to 2 pCi/L or below.

Sometimes short-term tests are less definitive about whether or not your program is above 4 pCi/L. This can happen when your results are close to 4 pCi/L. For example, if the average of your two short-term test results is 4.1 pCi/L, there is about a 50% chance that your year-round average is somewhat below 4 pCi/L. However, EPA believes that any radon exposure carries some risk - no level of radon is safe. Even radon levels below 4 pCi/L pose some risk, and you can reduce your risk of lung cancer by lowering your radon level.

If your day care space changes, you complete major renovations to the day care space and/or you begin occupying a lower level (such as a basement) re-testing must be conducted.

Verification of Radon Testing/Re-testing

If a provider living in a radon zone has already had his or her home tested for radon and can provide the test results, no re-test is required. Re-testing is not required every licensing period. Re-testing is required if a provider has major renovations or construction work completed in the provider’s home on the provider’s property, as these actions may alter radon results.

Additional Guidance and Information

Only mobile homes with permanent foundations need to be tested for radon.

There are radon detector devices on the market that remain in place in the home and continually test for radon and sound an alarm if the radon levels higher than the acceptable indoor level are detected. Many of these units work well and meet proficiency requirements. These units may not provide a printout, so a visual inspection is needed for verification.

Testing a residence on the third floor or above is not required unless the building is built into the side of a hill. In which case, testing must be done for rooms adjacent to exterior walls on the hill side of the building.
