Radon in Homes: What New York Homebuyers Should Know
Radon in Homes: What New York Homebuyers Should Know
Radon is a naturally occurring radioactive gas that can seep into homes and buildings from the ground. It's colorless, odorless, and tasteless, making it a silent threat. In New York, radon is the second leading cause of lung cancer, so understanding the risks and what you can do about it is crucial, especially if you're a homebuyer.
What is Radon and Why is it a Concern?
Radon forms from the breakdown of uranium in soil and rock. It can enter homes through cracks in foundations, walls, and gaps around pipes. Because it's a gas, it can accumulate in indoor air. The EPA (Environmental Protection Agency) and the New York State Department of Health have established action levels for radon. Elevated levels pose a significant health risk, increasing the chance of developing lung cancer.
Radon Testing: A Must for New York Homebuyers
Testing for radon is the only way to know if a home has a problem. It's a simple and inexpensive process. Here's what you should know:
- Hire a certified radon professional: While DIY kits are available, a certified professional ensures accurate testing and interpretation of results. They can also advise on mitigation if needed.
- Timing: Testing should ideally be done before finalizing a home purchase. This allows you to negotiate repairs or reassess your decision.
- Types of tests: Short-term tests provide results within a few days, while long-term tests offer a more accurate average over several months. A short-term test is often sufficient for real estate transactions.
Radon Mitigation: What if a Home Tests High?
If a home's radon levels are at or above the action level (4 picocuries per liter (pCi/L) in the US), mitigation is necessary. Common mitigation systems involve:
- Sub-slab depressurization: This is the most common method. It involves installing a pipe and fan to draw radon gas from beneath the foundation and vent it outside.
- Sealing: Sealing cracks and other entry points can help reduce radon levels, but it's usually not enough on its own.
Mitigation systems are typically effective in reducing radon levels significantly. It's important to have a certified professional install the system and conduct post-mitigation testing to ensure its effectiveness.
Protecting Your Family
Radon is a serious health concern, but it's one that can be addressed. As a New York homebuyer, taking the necessary steps to test for radon and mitigate if necessary is a crucial part of protecting your family's health.
