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.
