Radon is a cancer-causing radioactive gas. You can’t see, smell or taste radon gas, so if it is a problem in your home, the only way to know is by testing. Radon comes from the natural breakdown of uranium in soil, rock, and water. Radon rises up from the ground into the air, and can become trapped inside the walls of your home. According to the Environmental Protection Agency, radon is a leading cause of lung cancer in the United States, second only to smoking.
Tabor Northwest uses Sun Nuclear continuous radon monitors, which are approved by the Environmental Protection Agency for use in real estate transactions. Our monitors are very sensitive, accurate and annually calibrated. Air samples are taken at 1 hour intervals for 48 hours.
It is important that closed-home conditions be maintained during the 48 hour test, and for 12 hours prior. Any airflow in the home (open windows, doors, fans, etc.) can contribute to diminished, inaccurate radon levels.
The results are measured in picocuries per liter (pCi/L). For readings over 4.0 pCi/L, the Environmental Protection Agency strongly recommends taking action to reduce radon levels.
Radon levels can be reduced in a number of different ways. The most effective method of reduction is through the installation of a mitigation system. Mitigation systems pull radon gas out from underneath a home and expel it safely above living areas and out of breathable air.
It is estimated that nearly 1 out of every 15 homes in the United States, and 1 of every 3 homes in the Portland Metro area have elevated levels of radon (>4.0 pCi/L). Click the image below for an interactive map of radon levels in your area.
Tabor Northwest charges $150 for a 48 hour Radon Test when it is booked with a full home inspection. The results are emailed after the equipment has been retrieved from the testing location, by the end of the day.
