There is no Safe Radon Level! A half of American homes have a radon level above 0.67 pCi/L (the median level). The average (mean) radon level in US homes is 1.25 pCi/L, or three times higher than the average level outdoors. Nearly 8 million US homes, or 1 out of every 15, have radon levels above the EPA's 4 pCi/L action limit and nearly 1 out of 6 exceed the EPA's 2 pCi/L consider action limit.

"Radon ""Questions and Misconceptions"" Section" Answer: Radon levels vary from home to home. There are many instances of a house with over 100 pCi/L being right next to a house with less than 4 pCi/L.

Testing for Radon Test for radon in each of the lowest structural areas of the home. If your house has one or more foundation types, a test should be placed in or above each area. For example, if a home has a basement, test in the basement if anyone spends at least 7 hours a week in the basement. If the home has a crawl space, place a radon detector in the room above the crawl space. If the house has a cement floor, (slab-on-grade) place a radon detector in any room. Avoid testing in the kitchen, bathroom and laundry room. If a house has all three foundation types, all three areas should be tested for radon.

Radon in Minnesota Homes While radon is present everywhere, and there is no known, safe level, your greatest exposure is where it can concentrate-indoors. And where you spend most time-at home. Your home can have radon whether it be old or new, well-sealed or drafty, and with or without a basement.

It's Elemental For these reasons, there is some concern as to the amount of radon present within homes. Radon seeps into houses as a result of the decay of radium, thorium or uranium ores underground and varies greatly from location to location. On average, the earth's atmosphere is 0.0000000000000000001% radon. When cooled to its solid state, radon glows yellow.

Wipe Out Radon - Radon Mitigation Services Radon is an invisible, tasteless gas that can enter your home through cracks and holes in the basement walls and floor. When radon decays, the tiny, ratio-active particles are released into the air you breathe. Breathing in air containing radon may increase your risk of lung cancer.he results of a radon test will give you the level of your home’s indoor radon level. EPA recommends that action is taken to reduce the radon level in your home if the test results are 4pCi/L or higher.

Lesson 4: Background radiation How much radon there is in your house depends on how easily radon can come up through cracks in the floor and how easily it can escape. Some rocks produce more radon than others. Granite produces lots of radon. So some parts of the country have naturally higher radon levels than others.

- You can measure radon levels in your home in two ways: short-term testing and long-term testing. Short-term radon test kits stay in your home for 2 to 90 days. A short-term test will give you quicker results, but it won’t tell you what your radon levels are throughout the year because radon levels change over the course of the day, with seasons, and with weather changes.

Safe Radon Levels This is the simpler of the two questions. A safe level of radon gas is no radon gas. Radon gas is a carcinogen which causes lung cancer. The US EPA has put it plainly, stating, Any radon exposure has some risk of causing lung cancer.The lower the radon level in your home, the lower your family's risk of lung cancer..hile no level of radon gas is completely safe, as with most things in life we must balance the benefits and costs to find our own acceptable levels.

Radon (A Citizen's Guide to Radon) Radon is a naturally occurring radioactive gas that is colorless, odorless, and tasteless. It is formed by the natural breakdown of uranium in rock, soil and water.Radon gas moves up through the soil and can be drawn into our homes by slight pressure differences.ortunately, radon levels in homes, schools and buildings can be measured with a simple test. Testing for radon is easy, inexpensive and effective. If high radon levels are found, they can be reduced by using proven mitigation techniques.

Electronic Radon Detector Step 1: Test your home using a short-term test. If your result is 4 pCi/L or higher, take a follow-up test (Step 2) to be sure. Step 2: Follow up with either a long-term test or a second short-term test: For a better understanding of your year-round average radon level, take a long-term test. If you need results quickly, take a second short-term test.

Radon Fact Sheet Should you test for radon? Testing is the only way to know your home’s radon levels. There are no immediate symptoms that will alert you to the presence of radon. It typically takes years of exposure before any problems surface. The US EPA, Surgeon General, American Lung Association, American Medical Association, and National Safety Council recommend testing your home for radon because testing is the only way to know your home’s radon levels. Radon is a national environmental health problem. Elevated radon levels have been discovered in every state. The US EPA estimates that as many as 8 million homes throughout the country have elevated levels of radon. Current state surveys show that 1 home in 5 has elevated radon levels.

Unlike radon levels in homes, occupational radon limits are governed by law and regulations.utdoor radon levels in the U.S. range from 0.02 to 0.75 pCi/L (picoCuries per liter), averaging 0.4 pCi/L. But homes draw concentrated radon gas from the ground. Because radon is nine times heavier than air, elevated radon levels build up in basements and on lower floors.
