HOW RADON ENTERS YOUR HOME
Radon is a naturally occurring radioactive gas released from the decay of uranium in soil, rock, and water. Due to pressure differences between the soil and your home, radon is drawn into your house through foundation cracks and other openings. It can also be present in well water, and though it poses a smaller risk compared to soil radon, it can still contribute to indoor air contamination. While building materials may release radon in rare cases, soil-based radon is typically the primary source of elevated levels in homes.
RADON IS A CANCER-CAUSING, RADIOACTIVE GAS
Radon is responsible for tens of thousands of lung cancer deaths each year and is the second leading cause of lung cancer in the U.S., following smoking. The risk of lung cancer increases significantly for individuals who both smoke and live in homes with high radon levels.
WHAT DO YOUR RADON TEST RESULTS MEAN?
Any level of radon exposure carries some risk of lung cancer. The lower the radon level in your home, the lower the risk. Radon levels are measured in pCi/L, with the outdoor level typically around 0.4 pCi/L. The EPA recommends addressing radon levels of 4 pCi/L or higher and suggests reducing them to below 2 pCi/L. Testing can be done through short-term (2-90 days) or long-term (over 90 days) methods. For detailed testing guidance, see the EPA’s resources available on their website.
WHY HIRE A CONTRACTOR?
The EPA advises hiring a qualified radon mitigation contractor to address high radon levels, as the process requires specialized knowledge and equipment. Without the proper expertise, you might inadvertently raise radon levels or create other risks and additional costs. If you choose to handle the work yourself, be sure to seek training and certification through your state radon office.
WILL ANY CONTRACTOR DO?
The EPA recommends using a certified radon mitigation contractor to ensure effective radon problem resolution. To verify qualifications, check with your state radon office, as many states require professionals to be licensed or certified. In unregulated states, ask contractors about their certifications and adherence to industry standards, such as ASTM guidelines for radon mitigation. Some private programs also offer certification and ID cards with qualifications and expiration dates. For more details, visit your state radon office or explore private proficiency programs.
HOW TO SELECT A CONTRACTOR
When choosing a contractor to address a radon issue, it’s important to get multiple estimates, request references, and follow up with them to ensure satisfaction with the contractor’s work. Additionally, check with your state radon office or local consumer protection agency for information on contractors. This helps you make a well-informed decision and find a reliable professional for radon mitigation.
WHAT TO LOOK FOR IN A RADON
REDUCTION SYSTEM
When selecting a radon reduction method, factors to consider include the initial radon level, installation and operating costs, home size, and foundation type. Most systems cause some air loss, potentially increasing utility bills, with the extent depending on your climate, home design, and system choice. Systems with fans are more effective but may slightly raise your electric bill. It’s important to weigh these factors to choose the most suitable and cost-effective solution for your home.
RADON REDUCTION TECHNIQUES
A contractor can use various methods to reduce radon levels in your home, either by preventing radon entry or by reducing levels after it has entered. EPA recommends prevention methods, like soil suction, which draws radon from beneath the home and vents it safely. Contractors assess your home’s features through visual inspections and diagnostic tests, such as smoke testing and soil communication tests, to determine the best system. In some cases, concerns about backdrafting of appliances may also arise, requiring a professional inspection. Talk to the Atlantic Radon Mitigation Team to know more.
