Is your house on rock? Have you measured your radon levels lately? The Lincoln Library has radon meters to borrow from their Library of Things. If you haven’t seen the Library of Things, look for the DVD cases across from the circulation librarian.
The Airthings meter is put in a location, ideally a basement, and allowed to sit for at least 24 hours. If your radon does measure near or above the recommended levels, you can also obtain a one use kit from the state. Radon level should be under 4 pico curies per liter. Levels will be higher with windows closed and in the winter. Weather will also effect your reading so the electric meters at the library are handy for taking multiple measurements in various locations. Radon is an odorless gas that is created from the decay of uranium and other materials and is found in all soil with higher levels from granite, so even countertops emit radon. It is known to cause lung cancer from breathing in high levels over time.
