Bibliography: p. 5 Thiol compounds, such as glutathione, 2,3-dimercaptopropanol (BAL), propane-1,3-dithiol, and N-phenylaminopropanedithiol, were readily oxidized by x-rays, beta rays, and gamma rays. The ionic yield for this oxidation was about the same, 3 at pH 7, on irradiation with x-rays and with beta rays; it was 23 per cent less on irradiation with gamma rays. The ionic yield varied with the hydrogen ion concentration, increasing as the pH value increased. There was no reduction of oxidized glutathione on irradiation with dosages of x-rays and gamma rays which produced oxidation of the reduced compound. In the absence of oxygen, the oxidation of thiols by ionizing radiations was only 33 per cent of that obtained in the presence of dissolved oxygen. When the thiol solutions were irradiated in the presence of dissolved oxygen, catalase protected them from oxidation by 17 to 27 per cent. |

Cerium (IV) nitrate is readily extracted from aqueous solutions by tri-n-butyl phosphate, a solvent which is reasonably stable under the strongly oxidizing conditions. The conditions for extraction are not critical, and favorable extraction is not inhibited by perchlorates or acetates, but sulfates interfere. By oxidation with bromates and simultaneous exhaustive extraction by butyl phosphate, the cerium may be quantitatively extracted. The degree of separation of cerium from iron, zirconium, lanthanum, and praseodymium are discussed. Uranium and thorium are extracted by butyl phosphate; the first is easily removed beforehand, and the second may be separated by coprecipitation of ceric iodate. It is believed that cerium (IV) nitrate is extracted by butyl phosphate by virtue of the formation of a new complex. Some attempts were made to identify or characterize this new body, but no conclusive evidence was gained. |

It seems desirable to report here some preliminary observations on the scintillations produced in commercial naphthalene by the beta rays from tritium and by the bremsstrahlung coming from tritium occluded in tantalum. Of immediate interest is the lower limit set on the conversion efficiency from beta ray to visible light energy. A small amount of gaseous tritium was put in direct contact with finely powdered naphthalene crystals in a 15 cu cm glass Kjeldahl flask, an identical flask but without tritium being used as a control, to find the direct action of the betas. A tantalum disk containing tritium occluded throughout its volume was placed near a solid piece of naphthalene to investigate the effect of soft x-rays since this is almost a pure source of such radiation. Both sources produced scintillations which were observed with a 1P21 photomultiplier, the pulses amplified by a Los Alamos Model 501 amplifier. The photomultiplier was not refrigerated. The rise time and total pulse length, easily observed on a 248A Dumont scope were respectively 0.05 microsecs and 0.2 microsecs. The gas concentration was not well known because the initially too high counting rates necessitated two depletions. jg p.2 |

In certain exponential absorption experiments, notably measurements of cross sections by transmission, it is important to achieve minimum statistical error in a limited time, or to minimize the counting time required to measure the absorption coefficient with a preassigned accuracy. The conditions required to attain these ends, i.e., the geometry for optimum transmission, and the best apportionment of counting times among the incident and transmitted beams and background, have been investigated for a wide range of relative backgrounds (0.001 to 0.01), and for two geometries: (1) Beam area fixed, absorber thickness alone is varied, and (2) Beam area and absorber thickness are both disposable parameters, while the total amount of absorber intercepting the beam remains fixed. In both cases the incident flux density and the background rate are assumed constant. The optimum transmissions are shown to be, in general, considerably smaller than those commonly used in absorption experiments. Thus, in Case 1, a useful rule is to employ a transmission of about 0.1 for low backgrounds, 0.2 for moderate backgrounds, and 0.3 for high backgrounds. The following have also been determined: (a) minimum statistical error for a given total counting time, (b) statistical error and the best distribution of counting times for nonoptimum geometry, and (c) sensitivity of the accuracy or total counting time to deviations from optimum transmission. |
