Nevada Radon Education Program

Radioactive, colorless, odorless, tasteless noble gas

About the program

Extension's Radon Education Program is funded through an EPA grant to educate Nevadans about the health risk posed by elevated levels of radon in the home. The program offers literature, maps, educational presentations, and low-cost radon test kits.

About radon

Radon is a naturally occurring radioactive gas that has no odor, color, or taste and comes from the soil. Radon gas moves through the soil into the air, where it harmlessly spreads in outdoor air or enters buildings through the foundation and becomes trapped inside. When it enters a building and gets trapped inside, high levels can cause lung cancer. 

Radon is a carcinogen, a substance known to cause cancer in humans.  Radon is the number one cause of lung cancer in non-smokers. More than 21,000 Americans die of radon-related lung cancer each year.  Not everyone exposed to radon will get lung cancer, but the greater the radon level and the longer the exposure, the greater the risk of developing lung cancer. Mining studies show extended periods of exposure to low levels of radon over a long period of time caused lung cancer.

All homes, offices, schools, and preschools should be tested for radon.

Only testing shows a home's radon level

Since you can't see, smell or taste radon, testing is the only way to determine if you have a radon problem. A neighbor’s test result or results-based maps cannot determine the level in any home. Homeowners can measure radon levels in their homes themselves using inexpensive and easy-to-use test kits. 

Test kits

Radon test kits are available at your local Extension office.  Short term test kits are $11. Cash or check only unless ordering online here.  

Which test should I use?

  • The EPA recommends taking a short-term test first. 
  • If your test results come back between 4 and 8 , follow up with a long-term test to confirm your results. Long-term tests run from 91 days to a year. 
  • If the results from your initial short-term test come back over 8, perform another short-term test to confirm the results. Average the two short-term test results to determine the need for radon mitigation.
  • You should fix your home if the average of your short-term tests or the result of your long-term test is 4 or higher.

Buying a home? Know the radon level

The EPA recommends knowing the radon level of any home you are considering buying.  Many states require radon testing for real estate transactions.  For more information, visit radon information for the real estate professional.

 Many informed buyers and relocation companies have homes tested for radon before a home purchase, similar to inspecting a home for termites and building defects. If high radon levels are found, the buyer and seller should discuss the timing and cost of radon reduction. Current mitigation technology successfully reduces radon concentrations inside homes, lowering the health risk of lung cancer caused by radon. Informed sellers test their homes prior to listing, and if elevated radon levels are found, the seller should take steps to reduce the radon levels before placing the house on the market.

When testing for a real estate transaction, it is recommended that a qualified (certified) tester be used. A certified, professional radon tester may charge  $300 for the test, but results are available shortly after 48 hours. A certified tester knows the testing protocols, such as where to do the test, how to test and how long to test. A certified tester is a third party not involved in the sale or purchase of the home.

"My dad attended a meeting recently in Boulder City where you gave some information on Radon testing in your home. We very much appreciate you spreading the word of this invisible danger. We didn’t realize the seriousness of this issue until we read your literature."

-Bill Tobler

All homes, schools, and offices should be tested for radon gas

Radon test kits are available at your local Extension office. You may also order a short-term kit online. Test kits are $11.

The only way to know if you have high levels of radon in your home, office or school is to test for it. Testing is easy and only takes a few days. Results take a few weeks. If your test result is 4 or higher, the U.S. Environmental Protection Agency (EPA) recommends fixing the problem.

A cancer survivor who had exposure to radon

Heidi Nafman-Onda was diagnosed at the age of 55 with lung cancer. She was a healthy, active, non-smoker with zero respiratory symptoms before she was diagnosed. Heidi and her husband Pierre tested their home for radon and found high levels, a little above 8 .

“It’s surprising that we have requirements for safety devices like smoke detectors, seat belts and carbon monoxide detectors but people don’t regularly test for radon,” Heidi said. “In addition to screening for other environmental hazards in your home, every home should test for radon.”

Our intent in sharing Heidi's White Ribbon Project story is to underscore the importance of testing your home for radon. No discrimination is intended and no endorsement is implied.
