What state has the highest level of radon?
Alaska
Alaska has the highest radon levels of 10.7 pCi/L. Homeowners in Alaska are encouraged to test for radon every two years….Here are the 10 states with the highest Radon levels:
- Alaska (10.7)
- South Dakota (9.6)
- Pennsylvania (8.6)
- Ohio (7.8)
- Washington (7.5)
- Kentucky (7.4)
- Montana (7.4)
- Idaho (7.3)
What is considered a very high level of radon?
4 pCi/L
Radon levels are measured in picocuries per liter, or pCi/L. 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.
Where are radon levels highest in a house?
Radon levels are usually higher in basements, cellars and living spaces in contact with the ground. However, considerable radon concentration can also be found above the ground floor.
Is radon common in North Carolina?
High levels of radon have been detected in homes in all 100 North Carolina counties. It is most prevalent in the Blue Ridge Mountain region and in a band of four counties in the Piedmont — Warren, Franklin, Vance and Wake, where the gas is generated in large, subterranean granite formations.
How long does it take for radon to affect you?
Radon gas can damage cells in your lungs, which can lead to cancer. Radon is responsible for about 21,000 lung cancer deaths each year in the United States, though it usually takes 5 to 25 years to develop. Early signs and symptoms of lung cancer may include: persistent cough.
Does opening windows decrease radon?
Opening windows improves air circulation and ventilation, helping move radon out of the house and mixing radon-free outside air with indoor air. Make sure all your basement windows are open. Homes tend to have lower air pressure than their surroundings, which draws radon into the basement.
How quickly can radon affect you?
Radon gas can damage cells in your lungs, which can lead to cancer. Radon is responsible for about 21,000 lung cancer deaths each year in the United States, though it usually takes 5 to 25 years to develop.
Do Ceiling fans help with radon?
Ceiling fans can reduce radon levels by 50%. If used along with positive ion generators, ceiling fans are capable of reducing radon levels by 90%. This is achieved by a phenomenon called plate-out, which neutralizes radio-active particles.
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).
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 factors can change radon test levels up or down?
The level of radon can commonly be elevated in the warmer months. The reason that radon levels can go up and down in the summer is because of a temperature change, though this one is less extreme. During the day, the sun beats down and heats up the house from the outside in, but at night, there is a rapid cooldown.
What is the average level 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. Is a radon level of 5 bad? Safe radon levels. The best radon level measurement would be zero.
What are the different levels of radon?
the local geology,for example the uranium content and permeability of the underlying rocks and soils;
