1. what is radon?
Radon is an invisible radioactive gas that you can’ t taste or smell. It can only be detected through testing. It is produced by the natural break-down of uranium in rock, soil, and water. Some areas of the U. S. have higher levels of uranium than others, and thus, there is a greater chance that buildings in those areas may have higher radon levels. Regardless of location, any building can have a radon problem.
Radon enters a building by moving up through the ground and then through cracks and holes in the foundation. Buildings can trap radon, which can lead to harmful indoor levels.
