What are normal levels of radon?
The average indoor radon level is estimated to be about 1.3 pCi/L, and about 0.4 pCi/L of radon is normally found in the outside air. The U.S. Congress has set a long-term goal that indoor radon levels be no more than outdoor levels.
How much radon is too much?
Levels of 4 pCi/L or higher are considered hazardous. Radon levels less than 4 pCi/L still pose a risk and in many cases can be reduced, although it is difficult to reduce levels below 2 pCi/L.
What is radon gas map?
The Map of Radon Zones was developed in 1993 to identify areas of the U.S. with the greatest potential for elevated indoor radon levels based on indoor radon measurement data, geology, aerial radioactivity, soil parameters, and foundation types.
Does air conditioning reduce radon?
A decrease in the mean value of radon and its attached progeny was found when AC was working. The mean value of radon equilibrium factor F was also lower when AC was working (0.49) than when it was off (0.61).
Can air filters remove radon?
Air Purifiers are great for mold, dust, allergies, bacteria and viruses, and odors, but many people do not know that they can also help with toxins, gases and chemicals such as radon. The most important type of air filter to reduce radon levels is an activated carbon filter.
What does radon come from?
Radon is a radioactive noble gas that comes from the decay of radium in the soil. Radium is also a daughter or progeny nuclide of Uranium (Uranium decay). Radon is a colorless, odorless, invisible gas that can only be detected through the use of proper equipment and protocols.
Does rain make radon worse?
Certain types of weather can have a greater impact on your home’s radon levels. Wind and rain storms create the largest variables of radon levels when testing for radon gas. Rainier days tend to result in noticeably higher radon levels. This is because rainy days are often coupled with lower barometric pressure.
What states have radon problems?
Radon is only a problem in certain parts of the country. FACT: High radon levels have been found in every state. Radon problems do vary from area to area, but the only way to know if your radon level is too high; is to test your home. MYTH: A neighbor’s test result is a good indication of whether your home has a problem. FACT: It’s not. Radon
What state has highest radon levels?
Radon is present everywhere in the United States. Levels of the gas differ from state to state, but it is particularly high in North Dakota and Iowa. The U.S. Environmental Protection Agency’s Map of Radon Zones shows the potential for elevated radon levels for each county in the United States.

What areas are high in radon?
High radon areas of the U.S. have more uranium in the soil than others. Iowa, for instance, has the highest concentration in the country, because glaciers ground up granite rocks, a source of naturally-occurring radon, and deposited the mineral into the soil. This is also part of what makes farmland in the region so rich, however.
