Radon Testing

radalink_monitorMaster Spec offers radon testing using state-of-the-art Radalink TeleMonitors. These high-tech units are accurate, using sophisticated technology that eliminates the high or low bias of most passive type measuring devices - the kind you purchase at the hardware store, home center, etc. Hourly readings and tamper deterrents eliminate false accusations of human interference that can easily occur with other test devices. A personalized, informative report is emailed to you and Master Spec within one hour after the data is transmitted to Radalink's central analysis facility. No delayed test results!

Illinois Radon Map

radonThere is no reason to fear radon... simply have a test performed to find out if radon is present in your home. It the test reveals an elevated level of radon, a mitigation system can easily be installed and will reduce the radon to a harmless level.

Champaign County residents, please see the Illinois Emergency Management Agency's (IEMA) map of radon measurements for Champaign County.




  • Radon exposure is the leading cause of lung cancer in non-smokers; radon caused lung cancer in smokers as well.
  • There has been more epidemiological investigation exploring the association between radon (and its decay products) and lung cancer than any other environmental carcinogen. Experimental exposure in animals, occupational studies of radon-exposed minors, and direct observation from individuals exposed to radon in their homes provides a firm scientific foundation that documents radon is a major environmental carcinogen.
  • According to the Science Advisory Board, “radon inhalation is the largest source of collective radiation exposure (and presumably, radiation risk) to the U.S. population as a whole.”
  • Recently, the EPA and the Science Advisory Board increased their radon risk assessment by more than 50% and now estimate 21,000 Americans die of radon-induced lung cancer annually.
  • The World Health Organization (WHO) says radon causes up to 15% of all lung cancers worldwide.
  • Although lung cancer can be treated, the survival rate is one of the lowest for those with cancer. From the time of diagnosis, only 11-15% of those afflicted will live beyond five years, depending upon demographic factors.
  • Residential pooling studies from both North America and Europe provide direct evidence linking residential radon exposure to lung cancer; “These findings effectively end any doubts about the risks to Americans of having radon in their homes,” said Tom Kelly, Director of EPA’s Indoor Environments Division. “The research confirms that breathing low levels of radon can lead to lung cancer.”
  • Because radon is a Class A carcinogen, the EPA and the Surgeon General recommend ALL HOME OWNERS and ALL HOME BUYERS test for indoor radon.
  • In 2005, the U.S. Surgeon General issued a Health Safety Advisory warning Americans about the health risk from exposure to radon in the air.
  • Radon-induced lung cancer can easily be prevented by testing your home and reducing concentrations that are at or above EPA’s 4pCi/l Action Level.
  • Homes with elevated radon concentration can easily be fixed with the installation of an Active Soil Depressurization (ASD) System by a State of Illinois licensed radon mitigation contractor.
  • ASD systems also decrease moisture and other soil gases entering the home, reducing molds, mildews, methane, pesticide gases, volatile organic compounds and other indoor air quality problems.
