Radon Information

We offer lab-generated radon testing.

We place our radon tests according to requirements of the South Dakota Real Estate Commission.  Our short-term testing uses 2 radon test kits which stay in the home for two to four days.  We recommend the use a long-term testing device, such as the Pro Series 3 or AirThings Wave radon detectors.

Radon results are then available usually within 1-2 business days.

Radon is a cancer-causing, radioactive gas.

You cannot see, taste, or smell radon.

Radon is estimated to cause 21,000 deaths per year in our country.  It is the second leading cause of lung cancer.  Only smoking causes more lung cancer deaths. If you smoke and your home has high radon levels, your risk of lung cancer is especially high.

Radon can be found all over the U.S.

Radon comes from the natural (radioactive) breakdown of uranium in soil, rock and water and gets into the air you breathe. Radon can be found all over the U.S. It can get into any type of building homes, offices, and schools and any type of foundation. You and your family are most likely to get your greatest exposure at home, where you spend most of your time.  The latest research shows that radon levels can now double within a 24-hour period.

You should test for radon.

Testing is the only way to know if you and your family are at risk from radon.

You can fix a radon problem.

Radon reduction systems work and they are not too costly.  The average radon mitigation system in our area ranges from $800 – $2,000.  Some radon reduction systems can reduce radon levels in your home by up to 99%. Even very high levels can be reduced to acceptable levels.
