Isotopic compositions of xenon and krypton released from a sample of Belgian Congo pitchblende were measured mass-spectrometrically in stepwise heating experiments. Relative contributions from spontaneous fission of 238U, thermal neutron-induced fission of 235U and fast neutron-induced fission of 238U, to the production of fissiogenic xenon found in the ore were calculated to be 64.1, 18.8 and 17.1 percent, respectively.
