Radiogenic helium primarily is derived from uranium and thoriumseries decay reactions in the Earth's crust. The helium3/helium4 ratio of radiogenic helium is about 2×108 (Mamyrin and Tolstikhin, 1984). Mantle helium also may be present in ground water, but probably is rare in young ground water (Solomon and Cook, 2000).

Helium makes up about % of the earth's atmosphere. This trace amount of helium is not gravitationally bound to the earth and is constantly lost to space. The earth's atmospheric helium is replaced by the decay of radioactive elements in the earth's crust. Alpha decay, one type of radioactive decay, produces particles called alpha particles.
