What is radon?
Radon is a naturally occurring radioactive gas that forms when uranium in soil and rock breaks down. It can enter homes through foundation cracks, crawl spaces, and gaps around pipes. Radon is colorless, odorless, and invisible radioactive gas making testing the only way to detect it.
Why is radon dangerous?
Radon exposure is the second leading cause of lung cancer in the United States and the leading cause among non-smokers. Long-term exposure to elevated radon levels significantly increases lung cancer risk as well as other potential health issues.
How do I test my home for radon?
You can test your home using:
-
Short-term radon test kits (2–7 days)
- Certified radon professionals for testing and analysis
Tests should be placed in the lowest level of the home, especially basements!
When is the best time to test for radon?
Radon can be tested anytime of year, but winter is ideal. Homes are sealed during colder months, making results more accurate for assessing long-term exposure.
What radon level is considered unsafe?
The U.S. Environmental Protection Agency (EPA) and the NYS Department of Health recommend taking corrective action if radon levels are 4.0 picocuries per liter (pCi/L) or higher. Even levels between 2.0 and 3.9 pCi/L may pose health risks and can be reduced.
How much does radon testing cost?
Costs may vary due to size of home, number of basements, crawlspaces etc.
What is radon mitigation?
Radon mitigation is the process of a professional designed system being installed to reducing radon levels inside a home. The most common method is sub-slab depressurization, which uses a evacuation pipe and fan assembly to safely redirect radon gas outside and effectively reduce your indoor air concentrationÂ
Does radon mitigation really work?
Yes. Properly installed radon mitigation systems can reduce radon levels by up to 99%. Most systems lower radon levels within a few days.
How much does radon mitigation cost?
Radon mitigation typically costs vary depending largely on facts like home size and layout, foundation type, initial radon levels asthestics concerns etc.
Do new homes need radon testing?
Absolutely Yes! New homes can have high radon levels, even with modern construction. All homes—new or old—should be tested for radon frequently.
Should I test for radon when buying or selling a home?
Absolutely. Radon testing is highly recommended during real estate transactions. Testing early helps avoid delays and gives buyers peace of mind.
Is radon a problem only in certain areas?
Radon can be found in every state. While some regions have higher average levels, any home can have elevated radon, regardless of location. The Hudson Valley region is considered a High Radon Area as per the EPA and the NYS Department of Health.
