How to Tell if There Is a Radon Gas Leak

Short-term Test

• 1

  Buy a certified kit from the National Environmental Health Association or from the National Radon Safety Board.

• 2

  Install it inside your basement for up to 90 days.

• 3

  Close the basement windows and doors for at least half a day before beginning the test. Ensure that the basement remains closed for at least two days.

• 4

  Remove the detector from its location and check the reading. A display of 4.0 pCi/l to 9.9 pCi/l indicates that long-term testing is needed as a follow-up.

Long-term Test

• 5

  Place the detector, ideally, halfway between floor and ceiling and away from dampness and heat.

• 6

  Leave the detector in a place where it will not be disturbed but is visible, for between three and 12 months.

• 7

  Send the detector to the manufacturer when the test period is up. You will be notified of the results when the analysis is complete.
