Hensel, Jr, W E

Space recorders are used at Goodyear Atomic Corporation to measure low concentrations of uranium hexafluoride in gas mixtures comprising essentially uranium hexafluoride and nitrogen. The calculations of the amount of uranium hexafluoride are based on the assumption that nitrogen is the only gas mixed with the uranium hexafluoride. The effect of the presence of Freon-114 in such a mixture was investigated in laboratory tests by replacing nitrogen with Freon-114. The tests indicate that Freon-114 produces more ion pairs than nitrogen per molecule, thus increasing the sensitivity of the space recorder. Also, it reduces the background radiation level resulting from residual contamination below that raeasured in the presence of nitrogen. The sensitivity increased almost linearly with an increase in Freon concentration. The ionization energy per ion pair for Freon-114 was calculated to be 7.0 plus or minus 0.7 electron volts. (auth)
