RADON TESTING

Testing is simple and only takes 48 hours for a short-term computerized test. This test is ideal if you want an idea of what the radon level in the house is, or for a real estate transaction.

The radon test should be performed on the lowest floor of the house that is lived or is considered habitable space. In most cases testing is not be done in a cellar or crawl space.

Where testing has revealed an average of 3.9pCi/L or higher, reduction will be recommended as beneficial.
A level of 3pCi/L can be found in many homes and should not be considered a problem.

Before testing can begin all the windows and exterior doors in the house must be kept closed for 24 hours. During the testing period exterior doors can be used normally, but must be closed as soon as entered.

Windows must not be opened.
Doors to the basement must be kept closed.
Exterior doors to basement will be sealed, and cannot be used.
Whole house fans may not be operated.
The heat or A/C should be operated normally.

The testing computer is very small and self contained. Any tampering with, covering or moving of the testing computer is detected and recorded by the computer. Excessive opening of doors and windows, or ventilating by other means in an effort to reduce the radon level reading is also recorded by the computer.

Should the test results indicate that the results are questionable, the test will need to be done again using stricter monitoring methods and security seals on doors, windows and heating and air conditioning controls.
