Purchase a test kit
The Environmental Protection Agency (EPA) encourages all homeowners to test their residences for radon gas concentrations.
The National Radon Program Services at Kansas State University (K-State) has test kits available to purchase online. To be able to order a kit online, you will first need to create an account with the K-State Global Campus. Once your account has been created, log into the account and select the type of radon test kit you would like to order, and complete the steps for checkout and payment.
If you are a New Jersey resident, you MUST order short-term kits using this site:
New Jersey Resident Test Kits. Long-term kits are not available for New Jersey.
Test kits 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.
Short term test kits (3-4 days) are $15, which includes all costs. Just follow the instructions on the package and return the kit to the manufacturer for analysis at no extra charge. If you have completed a short term test obtained from this site, you can use the test's serial number to access your results at www.radon.com.
*Please note as indicated on the short-term test kit instructions from AirChek: Radon test kits must reach the lab at AirChek within 7 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.
Long term test kits (3-12 months) are $25, which includes all costs. Just follow the instructions on the package and return the kit to the manufacturer for analysis at no extra charge. If you have completed a long term test obtained from this site, you can use the test's serial number to access your results by calling Landauer Radon®, the manufacturer's, customer service line at (800) 528-8327.
