SAMPLE     Great Bear Lake pitchblende (29.0% 238U)               1354600100009 
METHOD     (CHSEP,ASEP) The rare gases in a sample of             1354600100010 
           pitchblende from Great Bear Lake, Canada, have now     1354600100011 
           been extracted, purified, and analyzed with a mass     1354600100012 
           spectrometer. The purified gas samples analyzed        1354600100013 
           contained about 5x10**-4 c.c. at N.T.P. of total       1354600100014 
           xenon and krypton. Five fission product isotopes of    1354600100015 
           xenon (Xe129, Xe131, Xe132, Xe134, Xe136, and three of 1354600100016 
           krypton (Kr83, Kr84, Kr86) have been identified. The   1354600100017 
           samples also contained some normal xenon and krypton as1354600100018 
            indicated by the presence of non-fission product      1354600100019 
           isotopes in abundances proportional to their           1354600100020 
           concentration in normal atmospheric gases.             1354600100021
