What is Radon?

Radon is the second leading cause of lung cancer in the U.S., and the leading cause of cancer among non-smokers.

Radon is a radioactive, carcinogenic gas, and one of the many naturally occurring minerals that make up different types of bedrock. It has no color, taste, or odor, even at very high levels. Radon enters our homes as gas through natural foundation materials and poured concrete foundations, and in our groundwater supplied by a drilled well. Even houses built on slabs can emit dangerous levels of radon. Homes without foundations can also have high levels of radon gases present. Houses over sand and gravel most commonly test at higher levels.

Left untreated, radon exposure over the course of time is proven to be a leading cause of lung cancer.

1 in 3 homes in Maine test too high.

Your exposure could equal smoking 2 packs of cigarettes a day!

No level of radon is considered to be safe, but the Environmental Protection Agency and the State of Maine consider a test level over 4 pCi/L (picocuries per liter) in the air and 4,000 pCi/L in water as an average level to be dangerous. For context – living in a house where you are consistently exposed to this level is a higher radiation exposure than is permitted for nuclear power plant workers. More than 25% of the homes tested in Maine are above 4 pCi/L, and it is not uncommon to see a house test over 50 pCi/L which, with annual exposure, equates to smoking two packs of cigarettes each day. Just because your neighbor’s house tests high, or low, does not mean your house’s test levels would be similar.

Millions of homes have elevated radon levels, and are completely unaware of the danger.

Should I have a radon test done?

Radon air and water tests (if you have a well) can reveal what the level is in your home. If you have a radon air level of 4 pCi/L or radon water level of 4,000 pCi/L or greater, take steps to remedy the problem as soon as possible. High levels of radon can be fixed with simple and affordable systems that can be installed in the span of a day. You should retest your home every two years, and retest any time make structural changes to your home or plan to finish your basement into a living space.

You should take action if:

  • Your real estate building inspection detected high levels of radon.
  • Your home is built on bedrock.
  • You have a finished basement (home gym, playroom, entertainment rooms).
  • You are concerned for your health.

It is better to have testing done so that you know what your radon levels are. If there is an elevated level of radon in your home’s air or water, take it seriously and get it corrected.
