It's the leading cause of lung cancer in the U.S. among people who don't smoke, and yet many people haven't heard about it or would know what to do if they had it.

That's according to Art Nash, an energy specialist with the University of Alaska Fairbanks Cooperative Extension Service.

Nash is working with state officials on a recommendation to have every Alaskan home tested for radon, a radioactive gas that, under the right circumstances, can seep from the ground and, in high levels, and with a long exposure, can cause serious illness like lung cancer.

The good news, according to Nash, is that radon is easy to test for and, if found in high levels, is often easy to fix. Sometimes it's as simple as sealing up cracks near the foundation of a house.

Nash said kits are available from the local Cooperative Extension Service, as well as most big box stores, and should sell between $20 and $40. For more information, click here.

The Cooperative Extension Service is also offering two free seminars on radon this week in Anchorage. The seminars will be held at the Atwood Building, 550 W. 7th Avenue on Wednesday, February 14, and Thursday, February 15, from 8 to 8:30 p.m.
