Notify the occupants of the importance of proper testing conditions. Give the occupants written instructions or a copy of this Guide and explain the directions carefully.
Conduct the radon test for a minimum of 48 hours; some test devices have a minimum exposure time greater than 48 hours.
When doing a short-term test ranging from 2-4 days, it is important to maintain closed-house conditions for at least 12 hours before the beginning of the test and during the entire test period.
If you hire someone to do the test, hire only a qualified individual. I am a Certified Radon Specialist.
The test should include method(s) to prevent or detect interference with testing conditions or with the testing device itself.
If the house already has an active radon-reduction system, make sure the vent fan is operating properly. If the fan is not operating properly, have it (or ask to have it) repaired and then test.
If your home has not yet been tested for Radon have a test taken as soon as possible. If you can, test your home before putting it on the market. You should test in the lowest level of the home which is suitable for occupancy. This means testing in the lowest level that you currently live in or a lower level not currently used, but which a buyer could use for living space without renovations.
If you are thinking of selling your home and you have already tested your home for radon, review the Radon Testing Checklist to make sure that the test was done correctly. If so, provide your test results to the buyer.
No matter what kind of test you took, a potential buyer may ask for a new test especially if:
- The Radon Testing Checklist items were not met
- The last test is not recent (e.g., within two years)
- You have renovated or altered your home since you tested
- Or the buyer plans to live in a lower level of the house than was tested, such as a basement suitable for occupancy but not currently lived in.
Radon Myths and Facts
MYTH: Scientists are not sure that radon really is a problem.
FACT: Although some scientists dispute the precise number of deaths due to radon, all the major health organizations (like the Centers for Disease Control and Prevention, the American Lung Association and the American Medical Association) agree with estimates that radon causes thousands of preventable lung cancer deaths every year. This is especially true among smokers, since the risk to smokers is much greater than to non-smokers.
MYTH: Radon testing is difficult, time-consuming and expensive.
FACT: Radon testing is easy and inexpensive. Especially compared to the alternative.
MYTH: Radon testing devices are not reliable and are difficult to find.
FACT: Reliable testing devices are available from qualified radon testers and companies.
MYTH: Homes with radon problems can't be fixed.
FACT: There are simple solutions to radon problems in homes. Hundreds of thousands of homeowners have already fixed radon problems in their homes. Radon levels can be readily lowered for $800 to $2,500 (with an average cost of $1,200)..
MYTH: Radon affects only certain kinds of homes.
FACT: House construction can affect radon levels. However, radon can be a problem in homes of all types: old homes, new homes, drafty homes, insulated homes, homes with basements, and homes without basements. Local geology, construction materials, and how the home was built are among the factors that can affect radon levels in homes.
MYTH: Radon is only a problem in certain parts of the country.
FACT: High radon levels have been found in every state. Radon problems do vary from area to area, but the only way to know your radon level is to test.
MYTH: A neighbor's test result is a good indication of whether your home has a problem.
FACT: It's not. Radon levels can vary greatly from home to home. The only way to know if your home has a radon problem is to test it.
MYTH: It's difficult to sell homes where radon problems have been discovered.
FACT: Where radon problems have been fixed, home sales have not been blocked or frustrated. The added protection is some times a good selling point.
MYTH: I've lived in my home for so long, it doesn't make sense to take action now.
FACT: You will reduce your risk of lung cancer when you reduce radon levels, even if you've lived with a radon problem for a long time.
