How does radon enter your home?
Public Health | Monroe County, NYBecause radon is a gas, it can leak into your house through the basement or crawl space –via adjacent or exposed soil and rock- or through well water. In a small number of homes, the building materials can give off radon. Radon enters homes through dirt floors, cracks in concrete walls and floors, floor drains, and sumps. When radon becomes trapped in buildings and concentrations build up indoors, exposure to radon becomes a concern.
Related QuestionsFAQs about Radon Mitigation, Concrete Sealing, and Basement ...The foundation is the most likely place for radon to enter the home. Concrete is porous by nature and by itself cannot block radon transmission. Radon is also water-soluble and attaches itself to the water molecules. As the water migrates through the wall or up from the floor it evaporates and the radon gas remains. If the basement has cracks in the floor or walls it creates another avenue for radon to enter your home.Related Questions

How Does Radon Enter A Property And How Can You Get Rid Of It?
Frequently Asked Questions on Radon - Radon FAQ - Craven Dis...It is best to stop radon entering a house or, if that is not practical, to try to remove it if it gets in. The aim in both cases should be to reduce indoor radon levels to significantly below the Action Level.
Related QuestionsWhy should I test my home for radon?
RADON QUESTIONS AND ANSWERSRadon is widely believed to be the second leading cause of lung cancer. Therefore, EPA and the Surgeon General recommend testing for radon in all homes below the third floor. Radon has been found in homes all over the United States. Any home can have a radon problem. On average, one out of every fifteen U.S. homes have a problem. The only way to know whether or not your home has a radon problem is to test for it.
Related QuestionsWhat can be done to reduce radon in a home?
RADON QUESTIONS AND ANSWERSYour house type will affect the kind of radon reduction system that will work best. Houses are generally categorized according to their foundation design. For example: basement, slab-on-grade (concrete poured at ground level), or crawlspace (a shallow unfinished space under the first floor). Some houses have more than one foundation design feature. For instance, it is common to have a basement under part of the house and to have a slab-on-grade or crawlspace under the rest of the house.
Related QuestionsHow does radon get into your home?
FAQRadon is a radioactive gas. It comes from the natural decay of uranium that is found in nearly all soils. It typically moves up through the ground to the air above and into your home through cracks and other openings in the foundation. Your home traps radon inside, where it can build up. Any home may have a radon problem. This means new and old homes, well-sealed and drafty homes, and homes with or without basements.
Related QuestionsHow does radon enter my building?
Radon FAQGenerally, radon is drawn into a building based on air pressure differentials. The ground beneath you building is generally under higher pressure than the basement or foundation. Air and gas move from high-pressure areas to low-pressure areas. Cracks in the foundation, plumbing openings, electrical openings, sump openings, etc..., can all serve as pathways for radon to enter the building.
Related QuestionsHow does radon get into a building?
RADON QUESTIONS AND ANSWERSMost indoor radon comes into the building from the soil or rock beneath it. Radon and other gases rise through the soil and get trapped under the building. The trapped gases build up pressure. Air pressure inside homes is usually lower than the pressure in the soil. Therefore, the higher pressure under the building forces gases though floors and walls and into the building. Most of the gas moves through cracks and other openings. Once inside, the radon can become trapped and concentrated.
Related QuestionsHow does radon get in water?
RADON QUESTIONS AND ANSWERSWhen the ground produces radon, it can dissolve and accumulate in water from underground sources (called ground water), such as wells. When water that contains radon is run for showering, washing dishes, cooking, and other uses, radon gas escapes from the water and goes into the air. Some radon also stays in the water. Radon can be a concern if your drinking water comes from a well that draws from an underground source, though not all water from underground sources contains radon.
Related QuestionsHow does radon move around?
Radon FAQIn most soils radon travels only a few feet before decaying. Thus, the radon that gets into your home comes from the soil immediately around and underneath your house. In water, rocks, or other dense materials radon doesn't even travel a few inches. Radon can move by diffusion ( concentration differences) or by advection (pressure driven). Radon travels into houses generally by a combination of diffusion and advection. Radon escapes from the ground into the atmosphere by diffusion. TOP
Related QuestionsShould a home built with radon-resistant features be tested?
RADON QUESTIONS AND ANSWERSYes. Every new home should be tested for radon after occupancy. Test your home even if it has the radon resistant features. Test kits are inexpensive and may be purchased at your local hardware store, or call the National Safety Council's Radon Hotline (800-767-7236) to order a test kit.
Related QuestionsHow do I know if my home has significant concentrations of radon?
Frequently Asked Questions (FAQ) | Monroe County, NYThe only way to know is to have your home tested. Radon detection kits are inexpensive and easy to use. You can purchase a kit at your local hardware store or other retail outlet, the local office of the American Lung Association ($20 per kit containing 2 tests) or we have a form to order a kit (single test) costing $6.25 from the New York State Department of Health (or you can call them at 1-800-458-1158).
Related QuestionsShould I get radon "check ups" for my home? Does the radon level vary?
Radon - FAQIf you have a home in which radon work has been done, I suggest an annual do it yourself test at New Year's. If your home has had modifications to the heating or air conditioning system, or if you have had renovation work done, I recommend that you radon test upon completion of such work. And, you bet, radon levels will vary by time of day, season, air temperature, precipitation, open or closed interior doors, wind, and more.
Related QuestionsWhat is radon?
RADON QUESTIONS AND ANSWERSRadon is a radioactive gas. It is colorless, odorless, tasteless, and chemically inert. Unless you test for it, there is no way of telling how much is present. Radon is formed by the natural radioactive decay of uranium in rock, soil, and water. Naturally existing, low levels of uranium occur widely in Earth's crust. It can be found in all 50 states. Once produced, radon moves through the ground to the air above.

Related QuestionsWhere Does Radon Come From?
Frequently Asked Questions on Radon - Radon FAQ - Craven Dis...When uranium decays, it becomes radium, and when radium decays, it becomes radon. Uranium is found in small quantities in all soil and rocks, but amounts vary from place to place. There can be marked variations even over small areas, and may be different levels of radon even between neighbouring buildings. Granite contains small amounts of uranium, which is why the South West has slightly higher levels than other parts of the UK.
Related QuestionsRadon FAQRadon is constantly being generated by the radium in rocks, soil, water and materials derived from rocks and soils. Radium is present at about 0.5 to 5 parts per million (PPM) in common rocks and soils. The radon generated in rocks or water usually stays trapped in that material unless the rocks are highly fractured or the water is mixed with the air. Radon generated in soil has about a 40% chance of escaping into the soil gas. TOPRelated Questions
