We recommend testing in the lowest livable level of your house (usually the basement), but it could be a bit up to your preference! Here’s why we recommend the basement:

  • Radon sits a little heavier than the air, so the highest concentration of radon is usually found in the lowest level of the building. By testing in the basement area you are basically testing for the “worst case scenario” of your home’s radon levels. It’s very rare that a house with low radon levels in the basement has high radon levels in the above floors!
  • Radon naturally occurs in the soil, so by testing the lowest level you are also testing closer to the most likely entry point of radon gas.
  • Most real estate transactions require that the lowest livable level is tested. This includes a level that could be lived in or modified to live in, so even an unfinished basement. Tests done for legal transactions or other legal reasons usually require specific testing directions; make sure to follow whatever procedures are set forth for your particular situation.
