Phys. Rev. 74, 1590–1594 (1948)The Occurrence of He3 in Natural Sources of HeliumReceived 27 August 1948; published in the issue dated December 1948 An investigation of the He3/He4 abundance ratio in helium extracted from the atmosphere, gas wells and a number of minerals has been made. Wide variations in this ratio are observed indicating that a more comprehensive program would be well worth while. He3 is observed in all sources of helium except radioactive minerals. This suggests the possibility of a primordial source as well as more recent sources for this isotope. © 1948 The American Physical Society URL:
