Radon Emission from Uranium Deposits
From what I hear Uranium miners are constantly under threat from radiation gas which is released from Uranium mines.
What I learned before is that there are 3 types of radiation. Alpha (helium), Beta (electrons), and gamma (photons). What kind of radiation releases radon gas. If its not radiation what is it? Uranium which gradually decayed into radon which is trapped under ground until the miners release it?
