What is an acceptable level of radon?
The US EPA has established the "action level" for deciding when you need to do something about radon. In your school, home or workplace, the action level is 4 pCi/l (picocuries per liter). Most states use the same level, but NJ uses 2 pCi/l. Many other countries use a level slightly less than 4 pCi/l.
What should I do if my radon level is high?
If you find a level higher than the EPA action level (4 pCi/l) you can install a radon mitigation system. The EPA says you should consider fixing your home if your level is between 2 and 4 pCi/l. A properly working mitigation system will effectively reduce your level.
Radon Information: Where
Where are the radon hotspots?
The EPA has developed a three zone system to help federal, state, and local officials target their resources and implement radon resistant building codes. The EPA recommends all homes in all zones should be tested for radon. Testing in your specific location is the only way to know your specific level. You can have a high reading in a zone with low potential, or a low reading in a zone with a high potential. Get more radon information to find out which zone you're in. See the EPA Radon Map
Where should I test in my home?
Many people believe they only need to test in their basement (if they have one). Our radon information suggests that testing in the basement is generally a good idea. However, it is almost always a false assumption that you should only test in the basement. Generally, you should test in the lowest livable level in your home AND in rooms above basements, crawl spaces and slabs AND in rooms where you spend a significant amount of time (e.g., bedrooms). HomeRadonTest.com has developed a wizard to help you determine where you need to test. Radon testing information to see where you should test for radon in your home.

Where can I get more radon information?
If you've already checked out the radon information on HomeRadonTest.com and still need more info, the US EPA has developed a primer on radon. It's available online at A Citizen's Guide to Radon Information .
Radon Information: When
When should I test for radon?
You should test for radon when you first move into your home. Schools, institutions and workplaces should also be tested before they are occupied and regularly thereafter.
When should I retest for radon?
The EPA suggests retesting every 24 months. Radon levels change with time. Even if your home has a radon reduction or mitigation system, you should still retest each year to ensure that your system is working properly. Without this radon information, your levels could slip into high risk.
When should I do a short term vs. long term test?
Short term radon tests are an excellent screening tool to help you determine your radon level quickly. However, for accuracy, do a short term (2-7 day) test AND a long term (3-12 month) test at the same time. There are seasonal variations in radon levels. For example, your home might show a low reading during the summer, but the radon information from a long term test may identify high levels during other times of the year.
When should I test my drinking water?
If your water comes from surface water such as a lake or river, you generally don't need to test. However, if your drinking water comes from a private or municipal well, you should test for radon in water. HomeRadonTest.com offers a radon in water test kit. Get a water test kit.
Radon Information: Why

Why should I test if my neighbor's home tested low?
Levels can vary greatly from one home to the next in the same neighborhood. You need the radon information from your own test for peace of mind.
Why is radon in my home?
Radon is gaseous and moves through fissures and cracks in the soil. When reaching the surface it mixes with the air, and is diluted to such low concentrations that it's relatively harmless. However, inside a building, radon can enter through openings such as cracks, loose fitting pipes, sumps, exposed dirt or gravel floors, slab joints, or porous block walls. Depending on the type of construction and concentrations in the soil, levels can vary greatly from house to house on the same street or in the same town.
