Airborne radon and radon daughters exist in every uranium mine and in several other underground mining commodities. Radon is radioactive gas. It diffuses into the underground mine atmosphere through the rock and the ground water. Radon decays in a series of steps into other radioactive elements, which are solids, called radon daughters. Radon and radon daughters are invisible and odorless. Decay of radon and its daughters results in emissions of alpha energy.
