Here's a handy widget with frequently asked questions and answers about
radon. To view an answer, just click on its "Answer" to see more. The questions
and answers on this page were collected from research and public information
resources by the federal, state and county governments, plus health organizations
whose goal it is to increase awareness of the importance of reducing your
exposure to radon.
Only a radon test can tell. That's because you can not
smell or see radon. Test for radon in the lowest level of your home where
people spend time. You may be able to get a free test kit from your county
government, or buy a radon test kit online, or at home improvement stores.
Exposure to radon can lead to lung cancer. That's because
the tiny radioactive particles in radon can lodge in the lining of the lungs,
and the radiation can damage lung cells, causing lung cancer.
Radon is natural. This colorless, odorless, radioactive
gas forms naturally from radioactive elements, such as uranium, which are
found in soil and rock everywhere in the world. Then, radon gas can move
into the air and water, and seep into our basements and living spaces.
Although radon can build up in any home, not all houses
have high radon levels. However, the EPA estimates that 1 in 3 homes have
high enough radon levels to pose a health risk.
Any style of home, with or without basement, can have a
radon problem, including old or new, drafty or insulated homes, and all
homes with or without basements. That's because any home can draw radon
in, even through concrete slab or blocks.
Even though the EPA has set an action level of 4 pCi/L,
recommending you take immediate measures to reduce your exposure to radon
gas, the EPA says that no level of radon can be considered acceptable (BEIR
Yes. Radon levels change seasonally and also daily. For
example, during cold weather, when the ground is covered with snow, the
air can't escape the ground outside, so levels above the snow outside may
go down; however, at the same time more radon can enter your home through
cracks in a basement floor or crawl space. The EPA recommends testing your
home on a yearly basis.
Rather than being afraid of radon, it's better to learn
more and take action to reduce your exposure to it. If you find out that
your home has unsafe levels, radon reduction systems are effective and inexpensive.
For those who can't afford it, there are government programs by EPA, HUD,
counties and others, to help fund radon reduction in homes. The cost of
fixing a home ranges from $800 to $2,500 ($1,200 is the national average) and less if you
do it yourself.
