Radon Issues | Radon Myths and Facts | Reducing Radon Levels


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. 

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.

MYTH: Short-term tests can't be used for making a decision about whether to fix your home.

FACT: A short-term test, followed by a second short-term test* can be used to decide whether to fix your home. However, the closer the average of your two short-term tests is to 4 pCi/L, the less certain you can be about whether your year-round average is above or below that level. Keep in mind that radon levels below 4 pCi/L still pose some risk.  Radon levels can be reduced in most homes to 2 pCi/L or below.


Your chances of getting lung cancer from radon depend mostly on:


  • How much radon is in your home

  • The amount of time you spend in your home

  • Whether you are a smoker or have ever smoked


  • Radon Risk If You Smoke

    WHAT TO DO:

    20 pCi/L

    About 260 people could get lung cancer

    250 times the risk of drowning

    Fix your home

    10 pCi/L

    About 150 people could get lung cancer

    200 times the risk of dying in a home fire

    Fix your home

    8 pCi/L

    About 120 people could get lung cancer

    30 times the risk of dying in a fall

    Fix your home

    4 pCi/L

    About 62 people could get lung cancer

    5 times the risk of dying in a car crash

    Consider fixing between 3 and 5 pCi/L

    2 pCi/L

    About 32 people could get lung cancer

    6 times the risk of dying from poison

    Consider fixing between 3 and 5 pCi/L

    1.3 pCi/L

    About 20 people could get lung cancer

    (Average indoor radon level)

    (Reducing radon 
    levels below 2 pCi/L is difficult.)

    0.4 pCi/L

    About 3 people could get lung cancer

    (Average outdoor radon level)

    Note: If you are a former smoker, your risk may be lower.

    It's never too late to reduce your risk of lung cancer.  Don't wait to test and fix a radon problem.  If you are a smoker, stop smoking.

    RADON IS A COLOURLESS AND ODOURLESS GAS THAT RESULTS FROM THE RADIOACTIVE DECAY OF RADIUM.

    It is the largest source of natural background radiation and contributes more than half of the total radiation dose received by most people. Radium, in turn, is produced through the natural decay of uranium. As small amounts of uranium are found in all soils throughout the world, radon gas is constantly being produced and released from the ground. It is therefore always present in the air.
