What is Radon?

Radon is a colorless, odorless radioactive gas that is naturally produced by the decay of uranium in soil and rock and then released into air and water. Radon levels are measured in picocuries per liter (pCi/L).

Radon seeps into your home from the ground beneath it. It can also be released into your home from well water or building materials that contain radon. Because they are typically closer to the ground, basements and first floors typically have the highest radon levels.

Colorado as a whole has a much higher propensity for  elevated radon levels then the national average. Nationally, about 1 in 15 homes will have elevated radon levels ( 4 pCi/l or greater ). In Colorado however, approximately 1 in 3 homes has elevated radon levels.

Testing Process

A typical radon test is generally 48 hours in length. The test unit will be placed in the lowest liveable space, or space that can be made liveable, within the dwelling. The test machine will make hourly readings of radon levels for 48 hours after which an average level of radon, measured in picocuries per litre (pCi/L) will be obtained. The test information from the test machine is then downloaded onto a computer and a report is generated detailing the results.

Peak Property Inspections LLC uses Sun Nuclear 1028 Radon test devices exclusively for all radon testing.
