What is Radon?

Accutech Home Inspections is the best Radon Testing in Southwest Ohio. Radon is a naturally-occurring radioactive gas that is produced as the uranium present in soil, rock, and water breaks down over time. Radon gas is found throughout the United States and can seep into homes through air and water posing a health risk. Specifically, the US EPA estimates that exposure to radon gas in the home is responsible for 20,000 lung cancer deaths each year.
Radon commonly enters a structure through:

  • Cracks in floors and walls
  • Gaps around service pipes and gaps in suspended floors
  • Cavities inside walls
  • Construction joints

More on radon testing Southwest Ohio

Radon is a colorless, odorless radioactive gas which comes from the natural breakdown (radioactive decay) of radium, which is a decay product of uranium. Uranium and radium are both common elements in the soil. The Surgeon General has warned that radon is the second leading cause of lung cancer in the U.S. today. Only smoking causes more lung cancer deaths. If you smoke and your home has high radon, your risk of lung cancer is especially high.

Where is radon found?

The major source of high levels of radon in homes is soil surrounding and under the house, particularly soil containing uranium. Radon is found all over the U.S. and the world. Some areas have more radon problems than others because of varying concentrations of radon-producing minerals in the soil, variation of soil types from one place to another, and different characteristics found in individual homes. Radon problems have been identified in every state. EPA estimates that as many as 1 in 15 homes have elevated annual radon levels.

How does radon get into homes?

house

Radon is a soil gas that typically moves up through the ground to the air above. Air pressure inside a home is usually lower than the pressure in the soil around the home’s foundation. Because of the pressure difference, a house acts like a vacuum, drawing radon in through dirt floors, hollow-block walls, cracks in the foundation floor and walls, and openings around floor drains, pipes, and sump pumps.
Any home may have a radon problem. This includes new, old, well-sealed, or drafty homes and homes with or without basements. adon is generally more concentrated at lower levels, like basements, ground floors, and first floors.

What levels are too high?

Radon is measured in picoCuries per liter (pCi/L) of air. A picoCurie is a measure of the amount of radioactivity of a particular substance. A liter is about equal to a quart. The level of radon in outdoor air is about 0.4 pCi/L. The average indoor radon level is about 1.3 pCi/L. EPA has established 4.0 pCi/L as the action level for radon in homes, schools and workplaces. This is a technology-based number, not a health-based level. Current mitigation technology can generally reduce radon levels to 3.9 pCi/L or less. Since radon is a carcinogen, no level is completely risk-free. However, since it is a natural part of the environment there is no such thing as a “0” level.

If my radon testing level is only 4.2 pCi/L, will it help to seal cracks in the floor? If so, with what?

However, if your home’s actual radon concentration is 4.2 pCi/L, sealing cracks in the floor and wall joints is a good first step in solving the problem. A gun-grade polyurethane caulk should be used. This should be considered a first phase, to be followed by another short-term test, and possibly other solutions.
