Important Radon Facts About Testing and Mitigation
Radon exposure poses serious health risks, yet many people are still unaware of the facts surrounding this dangerous gas. Understanding the risks and taking the proper steps can protect your family and home. Below are some essential radon facts to help you stay informed.
What is Radon?
Radon is an odorless gas formed from the decay of uranium in soil, rock, and water. As radon rises from the ground, it can become trapped inside buildings, including homes, schools, and workplaces.
In the United States, this gas is measured in (pCi/L). Despite being invisible and scentless, radon can pose a serious threat when concentrated indoors.
The Dangers of Radon Exposure
There are connections to lung cancer and radon gas. This is usually among non-smokers and the second-leading cause for smokers. It is estimated that radon gas contributes to roughly 21,000 lung cancer deaths in the U.S. annually.
According to the U.S. Environmental Protection Agency (EPA), four pCi/L or more radon levels are dangerous and require mitigation. However, even levels below this threshold can increase cancer risk, with the World Health Organization suggesting that radon levels should be mitigated if they exceed 2.7 pCi/L.
There is no safe level of radon gas, as any exposure carries a degree of risk. Radon exposure at a level of 1 pCi/L is equivalent to smoking 2.5 cigarettes a day.
How Common is Radon Gas?
Radon gas entering a property is more common than many people realize. The E.P.A. estimates that approximately one in 15 homes in the U.S. have elevated radon levels.
Certain geographic regions may experience higher radon concentrations due to the underlying rock and soil composition. Testing is the only way to know if radon is present, making it a crucial step for homeowners.
How Do You Test for Radon?
Testing for radon gas is straightforward and the first step in protecting your home. You can use a D.I.Y. test kit or hire a professional radon contractor to conduct the test.
It is essential to test if you live in an area known for high radon levels or if it has been a while since your last test.
When Should You Test for Radon?
Routine radon testing is recommended every two years to ensure levels remain safe. Specific circumstances that may call for more frequent testing include:
- Real Estate Transactions: Many states require radon testing as part of the home-buying process. Testing usually occurs during the home inspection phase.
- Post-Mitigation Checks: Once a radon mitigation system is installed, retesting every two years helps ensure its effectiveness.
- After Home Renovations: Major renovations can change the airflow in your home, potentially affecting radon levels. If your home’s HVAC system has been updated, it is wise to test again after making structural changes.
What is Radon Mitigation?
Mitigation typically involves installing a radon mitigation system that uses pipes and fans to vent the gas out of the home. Certified radon professionals design these systems based on your home’s unique structure and foundation.
Factors Affecting Radon Mitigation
Several factors can influence how radon mitigation is carried out:
- Foundation Type: Homes with porous foundations (like gravel) may allow for easier radon extraction than those built on solid ground or rock.
- Building Structure: Your home’s design and layout can impact how the mitigation system is installed. Pipes are often routed through walls and floors to carry radon safely to the roof. Depending on your home’s structure, the pipes may need bends and joints, which must be adequately sealed to prevent leaks.
- Multiple Systems: Homes with complex layouts or additions may require more than one mitigation system to reduce radon levels effectively.
Can Sealing Foundation Cracks Help?
Sealing cracks can help reduce radon entry, but it is not a standalone solution. While caulking and patching can limit some radon infiltration, they cannot eliminate the gas due to other potential entry points.
For this reason, sealing should always be combined with a properly installed radon mitigation system.
Radon Mitigation Costs and Considerations
The cost of installing a radon mitigation system is based on factors such as home size, foundation type, and the system’s complexity. However, the expense is comparable to other common home repairs, and the benefits to your health are invaluable.
Additionally, the system’s fan may increase your energy bill slightly, but this is a minor cost compared to the peace of mind that comes with reducing radon levels.
Finding a Qualified Radon Contractor
Choose a qualified radon contractor who meets state and local certification requirements to ensure the best results. A reputable professional will include the following in their services:
- Radon testing before installation to determine the extent of the issue
- A warning device to alert you if the mitigation system fails
- Post-installation testing to confirm reduced radon levels
- State certification, bonding, and insurance
Protect Your Home from Radon Exposure
Radon exposure’s effects are cumulative, meaning the longer you are exposed, the greater the risk. Since the gas is odorless and invisible, regular testing is crucial for detection and prevention. Take the first step by scheduling a radon test today.
