What is Radon Testing?

The intent of radon testing and inspection is to assess the level of radon in the home

During a radon test or radon measurement inspection, the specialist may uncover places of potential radon entry, and inform the clients of the test results and the possible need for follow-up testing and/or mitigation. Radon inspection has specific limitations. It typically includes only those areas of the building that are readily accessible and is limited to visual observations and a limited sample of the radon levels in a home. Most radon measurements are performed over a 48-hour period and therefore provide only a snapshot of the radon levels in the home.

A radon inspection is based on visual observation of the building's condition on the day of the inspection and the results of a radon test that indicate the levels of radon in the home during that particular time period. A radon inspection is not a warranty or guarantee that the home will always have the same levels of radon.

How much does a radon measurement usually cost?

The fee for a basic radon inspection/test (also referred to as a radon measurement) averages around $400

The fee for a radon test is largely dependent on the size of the house and the geographic area of the country. Radon inspections typically involve a visual inspection of the premises for any signs of possible radon entry points and a sample radon measurement test which generally takes 48 hours. In most cases an inspection is scheduled a few days to a week in advance, and a written report is normally submitted 48-72 hours following an inspection (i.e. after the results of the radon measurement test have been gathered and analyzed). Becoming a radon inspector is a great addition to home inspection services.

Health risks of radon in homes

Radon and Lung Cancer

High radon levels in a home are considered dangerous because of the link from radon exposure to lung cancer. Radon, an inert gas that is colorless and odorless, is highly radioactive. The radioactive particles produced from the decay of radon can get lodged in one's lungs, and potentially cause fatal health problems. Detecting radon has become of great importance, and the EPA recommends that EVERYONE test their home for radon. By taking this course, you will know how to measure amounts of this dangerous gas, and how much is considered hazardous. You will have the ability to help those who may be living with a fatal substance in their homes.
