The fission yields of the stable isotopes of xenon and krypton in natural fission have been determined for six samples of pitchblende and one sample of uraninite. The fission yields observed varied markedly from sample to sample. The nature of these variations and particularly the changes that occur in the "fine structure" of the mass yield curves at Xe132 and Xe134 indicate that both spontaneous fission of U238 and neutron fission of U235 occur in uranium minerals, the proportion of each depending on the uranium concentration, geological age, and the impurities in the mineral. This conclusion is consistent with estimates of the neutron flux in these ores based on the abundance of Pu239 in pitchblende.
