During radioactive decay, a material loses some of its energy by sending out particles and radiation.

Inside the crystal, radioactive decay occurs and tiny atomic fragments called alpha particles shoot away from the decaying nucleus, which recoils like a rifle.
Although helium does accumulate in the atmosphere through radioactive decay of heavy elements in the Earth's crust, the levels aren't high enough to make this a viable source.
For example, the radioactive decay of a radioactive isotope (as far as we have thus measured) is fixed and does not depend on normal physical variables - this is why carbon dating is regarded as a valuable tool by archaeologists.
