Radon comes from the breakdown of uranium found in rocks and soil underground. ๐ชจ
It can enter buildings through cracks in walls, floors, or even openings around pipes. Some areas of the USA, like the Appalachian Mountains, have higher levels of radon because of the granite rock that contains uranium. ๐
Other countries, like Canada, also have radon naturally found in their soil. Radon can also be found in well water, making it important to know where your water comes from! ๐ง
