Radon is an odorless, colorless, radioactive gas. It is also the second leading cause of lung cancer in the United States. The U.S. Environmental Protection Agency (EPA) and the Surgeon General’s office estimate radon is responsible for more than 20,000 lung cancer deaths each year. Since it is difficult to identify any immediate symptoms related to radon exposure, it may take years before health problems appear. So, whether in the workplace, in homes, or in schools, understanding radon
is important. This includes learning how radon gets into buildings, its health effects, and ways to reduce its levels.
Having your home tested is the only effective way to determine whether you or your family is at risk of radon exposure. Steps you can take to reduce radon levels include
- Testing your home or office
- Sending the kit to appropriate sources to determine
radon levels - Fixing your home if radon levels are high
How Radon Enters Your Home
Radon is a gas that occurs naturally from the breakdown—or the radioactive decay—of uranium. Rocks, soil, and in some cases groundwater can all contain uranium. Because radon comes from so many sources, people are easily exposed to it. Exposure can occur through breathing outdoor air, in buildings and homes, and by eating or drinking (ingestion). Radon gas can seep through cracks in buildings and expose people to the radiation, which can lead to severe health problems. The EPA lists the following ways that radon can get into buildings:
- Cracks in solid floors and walls
- Construction joints
- Gaps in suspended floors
- Gaps around service pipes
- Cavities inside walls
- The water supply
For information about radon levels, please see the EPA Radon Risks Chart.
Protection from Radon for You and Your Family
CDC worked with EPA to produce a booklet entitled A Citizen’s Guide to Radon: The Guide to Protecting Yourself and Family from Radon. Over the years, federal, state, and local agencies have used this citizen’s guide to alert and to inform people about residential radon risks. The publication includes information about the following:
- The risks of living with radon
- Lowering radon levels in your home
- How to test your home for radon
- What your test results mean
- How to lower the radon levels in your home
- Radon Myths
- Radon: Living Green Starts from the Ground Up
