Radon, Remodeling, and Ruin: Pennsylvania's Hidden Lung Threat
By Franklin Everett ShawAre you breathing easy in your Pennsylvania home? You might think so, but an invisible threat could be lurking: radon. This radioactive gas, a byproduct of uranium decay in soil and rock, is a significant health hazard, especially in older homes and areas with specific geological formations. Let’s dive into how Pennsylvania homeowners, particularly those in high-risk counties, can test for radon and take action to protect their families.
Radon is odorless, tasteless, and colorless. The only way to know if it’s present in your home is to test for it.
Pennsylvania’s geology makes it particularly susceptible to radon. The Reading Prong, a geological formation stretching across southeastern Pennsylvania, is known for high uranium concentrations.
This translates to elevated radon levels in counties like Berks, Bucks, Chester, and Montgomery. Even if you don’t live directly on the Reading Prong, fractured bedrock and soil conditions throughout the state can allow radon to seep into homes.
The EPA recommends that all homes below the third floor be tested for radon. In Pennsylvania, this is especially crucial.
Why is radon so dangerous? Prolonged exposure to radon is the second leading cause of lung cancer in the United States, after smoking.
The Surgeon General estimates that radon is responsible for about 21,000 lung cancer deaths each year. Pennsylvania, with its high radon levels, unfortunately sees a disproportionate share of these cases.
The Pennsylvania Department of Environmental Protection (DEP) provides valuable resources and information about radon testing and mitigation. They also maintain a list of certified radon testers and mitigators.
Testing for radon is relatively simple and inexpensive. You have two main options: DIY test kits or professional testing.
DIY test kits are readily available at hardware stores, home improvement centers, and online retailers. These kits typically involve placing a passive detector in your home for a specified period (usually 2-7 days) and then sending it to a lab for analysis.
The cost of a DIY kit ranges from $20 to $50, including lab fees. Follow the instructions carefully to ensure accurate results.
Professional radon testing involves hiring a certified radon tester to conduct the test. They use specialized equipment and follow strict protocols to ensure accurate and reliable results.
Professional testing typically costs between $150 and $300. This is a good option if you want a more comprehensive assessment or if you have concerns about the accuracy of DIY testing.
When choosing a professional tester, make sure they are certified by the Pennsylvania DEP. This ensures they have met the required training and experience standards.
Short-term tests are typically used for initial screening. If the results are elevated, a long-term test is recommended to get a more accurate average radon level.
Long-term tests are conducted over a period of 90 days or more. This provides a better representation of the average radon level in your home throughout the year.
The EPA recommends taking action if your radon level is 4 picocuries per liter (pCi/L) or higher. Even levels between 2 pCi/L and 4 pCi/L warrant consideration of mitigation.
If your radon test results are elevated, don’t panic. Radon mitigation systems are effective at reducing radon levels in homes.
The most common radon mitigation technique is sub-slab depressurization (SSD). This involves installing a vent pipe and fan to draw radon gas from beneath the foundation and vent it safely outside.
The cost of a radon mitigation system typically ranges from $800 to $2500. The exact cost will depend on the size and layout of your home, as well as the complexity of the installation.
DIY radon mitigation is possible, but it’s generally not recommended unless you have significant experience with home improvement projects and a thorough understanding of radon mitigation techniques. Improper installation can be ineffective or even create new problems.
Hiring a certified radon mitigator is the best way to ensure that the system is installed correctly and effectively. The Pennsylvania DEP maintains a list of certified mitigators in your area.
When choosing a mitigator, get multiple quotes and ask for references. Check their credentials and make sure they are properly insured.
Radon mitigation systems typically require minimal maintenance. The fan should be checked periodically to ensure it is operating properly.
Some mitigation systems also include a manometer, which indicates the pressure difference between the sub-slab area and the indoor air. This can help you monitor the system’s performance.
Pennsylvania offers financial assistance programs to help homeowners with the cost of radon mitigation. These programs are typically income-based and may be available through your local county or the state DEP.
Contact your local county health department or the Pennsylvania DEP for more information about financial assistance programs. Don’t let cost be a barrier to protecting your family from radon.
Real estate transactions in Pennsylvania often require radon testing. Sellers are typically required to disclose any known radon hazards to potential buyers.
If you are buying a home in Pennsylvania, it’s a good idea to have a radon test conducted as part of the home inspection. This will give you peace of mind and allow you to negotiate any necessary mitigation measures with the seller.
Even new construction homes can have elevated radon levels. Radon can enter through cracks in the foundation, gaps around pipes, and other openings.
Radon-resistant new construction (RRNC) techniques can be incorporated into the building process to minimize radon entry. These techniques include installing a vapor barrier, sealing cracks and openings, and providing a passive vent pipe.
If you are building a new home in Pennsylvania, consider incorporating RRNC techniques to protect your family from radon. This is a relatively inexpensive way to reduce your risk.
Radon is a serious health hazard, but it’s also a preventable one. By testing your home and taking action to mitigate elevated radon levels, you can protect your family from lung cancer.
Don’t wait. Test your Pennsylvania home for radon today. Your health depends on it.
