Radon Testing

Radon is a colorless, odorless, radioactive gas that can lung cancer. Radon is present in the basement of many houses, particularly houses in New England and the western mountain states. Testing for high concentrations is a wise precaution.

Professional Testing

The simplest way to test for radon is to hire a professional. Professional testers can provide a full range of water and air testing. Look for one certified by an EPA approved authority.

Do It Yourself Testing

A lower cost alternative is to do it yourself with a test kit that may be purchased over the internet.

  • Water test kits sample the amount of radon gas dissolved in your home's water that may escape during showering, dishwashing, and other uses. Once you receive the kit in the mail, you fill test tubes with water samples from you home and mail them to a testing laboratory. A test report returns in the next few weeks detailing the detected levels.
  • Air test kits may also be purchased on line. They consist of one or more metallic canisters that collect the gas over a period of two to four days for short term testing or from three to twelve months for long term testing. Several canisters are better than a single one to get an impression of levels throughout your home and control for a mistaken reading. Long term testing provides a more accurate indication of your exposure because it averages out fluctuations due to weather and seasons.

You may also want to consider purchasing an electronic monitor that plugs into the wall (similar to a carbon monoxide monitor). These continuously monitor the level of
radon in the air and display the average concentration over the past week.
