Detailed explanation-1: -Radon (chemical symbol Rn) is an odorless, colorless, radioactive gas. It comes from the natural decay of uranium and radium found in nearly all rocks and soils. Radon can move up from the ground into buildings through openings in floors or walls that are in contact with the ground.
Detailed explanation-2: -Alpha radiation, beta radiation, and gamma radiation are emitted out under the radioactive decay chain of radon.
Detailed explanation-3: -When the natural radioactivity found in building materials decays, it releases the radioactive gas radon. This release of radon may contribute to elevated radon levels in homes and buildings. Indoor radon is a more common and a far larger public health risk than radiation from building materials.
