RadonEye Radon Detector


Radon is an odorless, invisible, radioactive gas naturally released from rocks, soil, and water. Radon is a chemical element with the symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless noble gas.  Radon can get into homes and buildings through small cracks or holes and build up in the air. Over time, breathing in high levels of radon can cause lung cancer.
