Utah Radon Information
Radon is a Cancer-Causing, Radioactive Gas
People cannot see, taste or smell radon. But it may be a problem in your home.
Radon is estimated to cause many thousands of deaths each year. That's because
when you breathe air containing radon, you can get lung cancer. In fact, the
Surgeon General has warned that radon is the second leading cause of lung cancer
in the United States today. 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 result in a high indoor radon level. But you
and your family are most likely to get your greatest exposure at home, where you
spend most of your time.
You Should Test for Radon
Testing is the only way to know if you and your family are at risk from radon.
EPA and the Surgeon General recommend testing all homes below the third floor
for radon. EPA also recommends testing in schools.
Testing is inexpensive and easy - it should only take a few minutes of your
time. Millions of Americans have already tested their homes for radon (see How
to Test Your Home).
You Can Fix a Radon Problem
Radon reduction systems work and they are not too costly. 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.
New Homes Can Be Built with Radon-Resistant Features
Radon-resistant construction techniques can be effective in preventing radon
entry. When installed properly and completely, these simple and inexpensive
techniques can help reduce indoor radon levels in homes. In addition, installing
them at the time of construction makes it easier and less expensive to reduce
radon levels further if these passive techniques don't reduce radon levels to
below 4 pCi/L. Every new home
should be tested after occupancy, even if it was built radon-resistant. If radon levels are still in
excess of 4 pCi/L, the passive system should be activated by having a
qualified mitigator install a
vent fan. For more explanation of radon resistant construction techniques, refer
to EPA publication, Building
Radon Out: A Step-by-Step Guide on How to Build Radon-Resistant Homes.
How Does Radon Get Into Your Home?
Radon is a radioactive gas. It comes from the natural decay of uranium that is
found in nearly all soils. It typically moves up through the ground to the air
above and into your home through cracks and other holes in the foundation. Your
home traps radon inside, where it can build up. Any home may have a radon
problem. This means new and old homes, well-sealed and drafty homes, and homes
with or without basements.
Radon from soil gas is the main cause of radon problems. Sometimes radon enters
the home through well water. In a small number of homes, the building materials
can give off radon, too. However, building materials rarely cause radon problems
by themselves.
