The radon levels in a home can be tested and mitigated by Thrasher, your local radon specialist in Nebraska, Iowa, and Missouri. Contact us today for solutions to your home's radon problems.
As a gas, radon can enter any home through cracks, holes, or any other openings. In particular, radon enters homes through a process known as the "stack effect", which practically sucks the gas right into the home.
Because the pressure in your home is lower than the pressure outside your home, a vacuum is created. As the warm air in your home rises, it makes its way out through the upper levels and attic and is replaced by air and moisture that is pulled in from the bottom levels of your home.
The air pulled in from below can contain radon gas, which will build up quickly in cooler weather when windows and other normal escape routes are kept closed. There could be only a little radon or a lot of radon, which is why every homeowner should test for radon on a regular basis.
Radon is measured in picocuries per liter (pCi/L) and the smaller the number the safer you are. However, even small amounts of radon may not be all that safe, but most homes can be mitigated and have the levels reduced.
Monitoring radon levels is a key step for ensuring your home is protected.
As a standard, the Environmental Protection Agency (EPA) has defined 4.0 pCi/L as the "action level" for any indoor environment. This means that a radon test result of 4.0 pCi/L or above needs to be mitigated to reduce radon levels as soon as possible.
The EPA estimates .4 pCi/L as the national average for the outdoor air, while 1.5 pCi/L is the national average for the indoor air. Although these averages are seemingly quite low, even this 1.5 pCi/L could be problematic. When this amount is trapped within a home, it's far more concentrated than if it were outside.
The World Health Organization (WHO) claims that radon can be dangerous in any concentration, which is why radon reduction systems are so important. These systems constantly work to lower the radon levels in your home.
"Most radon-induced lung cancers occur from low-and-medium-dose exposures in people's homes. Radon is the second most significant cause of lung cancer after smoking in many countries," said Dr. Maria Neira of the WHO.
Experts at the EPA agree: "We know that radon is a carcinogen. This research confirms that breathing low levels of radon can lead to lung cancer," said Tom Kelly, the director of the EPA's Indoor Environments Division.
As long as your home is below 4.0 pCi/L, you should have some peace of mind. However, Thrasher wants to do everything possible to get the radon levels as low as possible. Contact Thrasher today for radon testing in NE, IA, and MO.
Maybe 10 pCi/L doesn't sound all that bad, so 4.0 pCi/L can't be a problem at all. In order to understand the number, you have to understand the measuring system. Let's compare some figures.
