Is radon high in Kansas?
In Kansas we have high levels of radon in our soils. The average observed residential radon test in Kansas is currently 5.4 pCi/L, which is in excess of the EPA’s action level of 4.0 pCi/L. The maximum reported radon value in Kansas to date is 1121.6 pCi/L.
How do you know if you are in a radon area?
Take a look at our radon maps and if you live in an area likely to be affected by higher levels of Radon, you can get your property tested. Testing is easy. You place a plastic detector about the size of a biscuit in your living room, another in your bedroom and leave them for three months.
Where are you most likely to encounter radon in a house?
Radon gas enters houses from the ground through cracks in concrete floors and walls, through gaps between floor and slab, and around drains and pipes, and small pores of hollow-block walls (fig. 2). Consequently, radon levels are usually higher in basements, cellars and ground floors.
Where is radon most common?
It sometimes gets concentrated in homes built on soil with natural uranium deposits. It can enter buildings through cracks in floors or walls, construction joints, or gaps in foundations around pipes, wires or pumps. Radon levels are usually highest in the basement or crawl space.
How common is radon in Kansas?
More than 112,000 radon measurements have been reported in Kansas, according to the Kansas Department of Health and Environment. The agency indicates that the statewide average indoor radon level in Kansas is 4.9 picocuries of radon per liter (pCi/L), which is above the EPA threshold of 4.0.
What type of soil has the most radon?
Granitic type soils
Granitic type soils present higher levels of radon gas. Non-granitic soils have traditionally been considered to have very low radon levels.
Is radon highest in basement?
Also, once the windows, doors, or vents are closed, the radon concentration returns to the previous level within hours according to EPA studies. FACT: Its concentration is usually the highest in basements, simply because it emanates out of the soil through the basement.
What is the average radon level?
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.
