Radon
What is Radon?
Radon is a naturally occurring, odorless, tasteless, colorless radioactive gas that can cause lung cancer. It is a byproduct of
naturally occurring decay of uranium in rock, soil and water. Between five and ten percent of the homes in Wisconsin have
radon levels above the US EPA guideline of 4 pCi/L average on the main floor. Every region of Wisconsin has some homes with
elevated radon levels.
Because radon is a gas it is capable of moving through the soil and structures to the water below the
ground surface and to the air above. Homes and buildings can trap air containing radon and cause a
health concern. Radon charged dust particles can be inhaled; these radioactive particles cling to lung
tissue and decay there. The lung damage caused can lead to lung cancer. Radon is the second leading
cause of lung cancer after smoking, according to a recent report from the National Academy of Sciences.
Who should test for Radon?
The United States Environmental Protection Agency and the Surgeon General strongly recommend that all homes be tested for
radon and, if a problem exists, corrective action be taken. The only way to tell if radon is present in your home is to test. Radon
test kits are available at the Health Department for $10.00 each.
Please stop in, call 715-528-3426 or email the Administrative Assistant at akrenzke@florencecountywi.gov to get your kit.
