It’s a naturally occurring radioactive gas from the natural breakdown of uranium (radioactive decay). Radon is typically found in soil and igneous rock, and sometimes in water as well. It can be found across the U.S., especially in central Kentucky. Radon quickly dilutes when it releases into the air. As a result, it seeps into buildings through gaps, cracks, and holes.
Natural Sources of Radon
There are multiple natural sources of Radon; some of them are as follow;
- Uranium Ores: It’s found in many soil deposits globally.
- Shales: It’s a sedimentary rock that is formed from clay and mud.
- Igneous Rocks: Rocks that are formed from lava or magma cooling (graphite).
- Phosphate Rock: it contains a higher amount of phosphate level, commonly found in clay.
- Metamorphic Rocks: rock that forms due to the transformation of other rocks forms (marble).
Limestone is also listed down in Radon’s natural sources, but we can’t accept a high level of Radon produced by its decay. An important thing to note is Radon doesn’t result from the decay of natural sources but through different manufactured structures.
Although Radon is primarily found in outdoor air, it becomes more of an issue when building through the basement walls or floor. This is because it usually moves up through the ground to the air above and into your building through cracks and other holes in the foundation. As a result, your home can easily trap Radon inside, where its concentrations can then build up.
Radon in Drinking Water
If the drinking water is exposed to any level or amount of Radon, it may still be considered dangerous for your health. Yes, if the drinking water source is in contact with Radon containing soil, it can easily dissolve in the water. From there, it could enter your home. A standard safe limit is 2.6pCi/L, and if the Radon level goes beyond this, it can pose a severe health threat.
