Radon Gas Inspection
The most accurate radon test is conducted by a certified individual with a properly calibrated electronic Continuous Radon Monitor. During the radon gas inspection, the monitor is placed on the lowest level of the home away from walls, windows and air vents. The radon monitor is then programmed and activated. Each hour for 48 hours, the radon monitor samples the air and records the amount of radon present.
During radon gas inspection, it’s important that certain guidelines are followed by the seller or occupant. A good radon gas inspector will have a legal document the seller must sign that indicates their agreement to:
• Keep windows and doors closed during testing (normal traffic is acceptable)
• Keep attic fans or whole house fans off
• Ensure the radon monitor is not moved or tampered with.
After the radon test, the inspector will download the results from the monitor and render them in an easy to read format such as the chart pictured above. The results are then delivered in writing to the home buyer as well as the buyer’s real estate agent.
Important note: An experienced radon gas inspector will have an electronic radon monitor that has a motion and temperature sensor. This protects home buyers by automatically reporting red flags such as motion alarms when the machine is moved or temperature swings if windows or doors are opened for too long.
Radon Gas Hazards & Symptoms
Radon is the leading cause of lung cancer in non-smokers. 3,000 deaths per year are attributed to Radon gas. Radon enters the human body through inhalation or ingestion. Those who smoke and have Radon present in their home are at an even higher risk of lung cancer.
A family living in a home with a radon level of 4.0 pCi/l will be exposed to 35 times as much radiation as the Nuclear Regulatory Commission would allow if standing next to a radioactive waste site. The radioactive alpha particles emitted by radon are the same as the alpha particles in plutonium and other dangerous radioactive substances.
There are no immediate symptoms for radon exposure. The effects are long term. Symptoms of lung cancer from radon exposure include:
Shortness of breath
Coughing up blood
Frequent respiratory infections
Loss of appetite

Radon Inspection Vs. Contractor
Beware of radon mitigation contractors who offer testing. The meat of their business is in fixing the home by installing a radon mitigation system. A truly impartial Radon gas inspector is only interested in determining the amount of radon in your home, not in fixing it.
We highly recommend using two separate individuals or companies. One for Radon testing and another for radon mitigation, if needed.
We provide radon testing only and serve the following areas in Missouri. Troy, Warrenton, Wentzville, O’Fallon, Winfield, Moscow Mills, New Melle, Dardenne Prairie, Jonesburg, Hawk Point, Old Monroe and surrounding areas.
Radon Testing Frequency
We recommend radon testing your home twice per year, once at the least, under differing weather conditions. This is true whether radon levels were high or low during previous tests. Radon gas levels can change by season, temperature, atmospheric pressure, weather, aging of the home, etc.
If you have a radon mitigation system installed, it’s even more important to conduct frequent testing. A mitigation system means there’s been a problem in the past. You want to ensure it’s working properly. Conditions change and systems fail.
