The Environmental Protection Agency (EPA) encourages all homeowners to test their residences for radon gas.

If you are testing in New Jersey, there will be an additional $10 payment for the New Jersey State Radon Fee or your results will not be released (see Instructions).  Additional information must be entered online for the New Jersey DEP.

Test kit purchases from individuals outside the United States are not supported/accepted by our system due to shipping costs and time delays which can impact the analysis process of the test kits.

*As indicated on the short-term test kit instructions from Alpha Energy:  Radon test kits must reach the lab at Alpha Energy Laboratories within 10 days of concluding the test in order for test results to be accurate.  Although your kit comes with pre-paid First Class postage, slower service and severe delays in First Class mail service have been experienced due to the United States Postal Service (USPS) budget crisis and subsequent facilty closures.  We strongly encourage you to consider an alternate shipping method, as outlined in your kit's instruction sheet.
