Radon Level Measurement


Check Master Home Inspections can check for radon at the time of inspection if requested. Our home inspectors do a short-term radon tests. We place a Canister for a minimum of 48 Hours and then we pick it up, seal it, and then send for lab testing. The results are received with in 4 days usually.   We then send the client the documented radon level and report with our recommendations in our radon level measurement report. 


Radon is a naturally occurring radioactive gas that can cause lung cancer. It is the second leading cause of cancer after smoking. You can’t see or smell radon. Testing is the only way to know the level of exposure. Radon can have a big impact on indoor air quality. 

How Rason Enters the home:   Radon levels are very low outdoors, but can accumulate to high concentrations in the home. This depends on radon levels in the soil, pathways for radon to enter the home, and the driving force. Air pressure differences between outside air and the inside air act to drive radon into the home. Some homes pull more radon into the home than others due to greater pressure differences available pathways.

  • Pathways – Routes the gas takes to enter the home, usually through openings between the soil and the home. These may include cracks in the concrete slabs or basements, floor-wall joints, an open sump pit or untreated crawl space, etc.
  • Air pressure – Differences in air pressure between the home’s interior and the soil can pull radon gas into the home through the pathways.
