South Tahoe Association of Realtors is hosting a class about radon on April 26 from noon-1pm.

The free talk will be at STAR’s office, 2307 James Ave. in South Lake Tahoe.

The guest speaker will be Jim Gorman of Tahoe Radon. Gorman is a licensed contractor and is certified by the National Radon Proficiency program. He will be covering radon in the Tahoe basin, the potential risks and how to mitigate them as well as create a safe environment.

Radon is a radioactive gas that comes from uranium-rich decomposing granite. Many Lake Tahoe homes have high levels of radon gas. After cigarette smoking, it is the second leading cause of lung cancer.
