Radon Measurement

What is Radon?

Radon is an odorless, invisible gas. It cannot be detected by the senses and can be confirmed only by sophisticated instruments and laboratory tests. The gas enters a house through pores and cracks in the concrete or through floorboards of poorly ventilated crawlspaces, especially when wet ground allows the gas to escape easily through the soil and disperse in the atmosphere. Radon is a lung carcinogen: the National Academy of Sciences estimates radon causes some 15,000 to 22,000 lung cancer deaths annually.

The U.S. Surgeon General and the EPA recommend all houses be tested for radon. Learn more about Radon.

Radon Measurement

The first step in protecting your family or employees from this cancer-causing gas is to have your home or property's radon level measured. Comfort Systems USA employs certified Radon Measurement Specialists, licensed by National Radon Defense. We use a Continuous Radon Monitor test, the most accurate and short-term radon test available. This test typically provides a precise radon level reading in about 48 hours.

 Radon Measurement Specialists go through extensive training, certification, and continuing education with the EPA in order to provide the most up-to-date, accurate results to our customers. If you are selling or buying a home, using a licensed Radon Measurement Specialists to perform the test is typically required.

Radon Mitigation

The Environmental Protection Agency (EPA) has established recommended concentration levels that minimize exposure and health risks. The EPA recommends that home or property owners implement a mitigation system if the results of one long-term test or the average of two short-term tests show radon levels of 4 pCi/L (or 0.02 WL) or higher.

Don't worry if your radon test reveals a high concentration of radon gas in your interior air. No matter how high your radon levels are, you can be confident that an experienced Radon Mitigation Specialist will be able to reduce radon levels effectively and affordably. In fact, most home radon reduction systems can be installed in less than 1 day.

There are several methods or systems available from preventing radon gas from entering the home while and reducing radon levels after it has entered the building. The EPA generally recommends methods that prevent radon from entering, such as soil suction, that draws the radon from below the basement or crawl space floor pushes it out into the outside air. Other radon reduction techniques that can be used in any type of house include: sealing, house/room pressurization, heat recovery ventilation, and natural ventilation.
