Radiotoxicity of Injected SR89 for Rats, Mice, and Rabbits. Part II. Metabolism and Organ Distribution

Description: Mice, rats and rabbits excreted Sr89-Sr90 very rapidly following intraperitoneal or intravenous administration. The greatest part of the excretion took place during the first three days, and by 10-15 days virtually no more of the retained strontium was excreted.

The Influence of Isotopic Composition on the Maximum in the Cosmic Ray Energy Spectra

Description: "The previously found maximum in the cosmic radiation energy spectrum is discussed, and the possibility that it arises in part from a misinterpretation of the data due to oversimplifying assumptions about the composition of the beam is examined. The importance that lack of recognition of isotopic composition may have is pointed out, and it is clear that this importance is strongly dependent on the measurements made and on the cut-off rigidity."

Preparation of U233

Description: Technical report. The object of the research is to determine the procedure and equipment for the preparation of U233 on a semi-works scale. The general proposed procedure is that thorium carbonate in aluminum cans will be irradiated with pile neutrons. The Pa233 resulting from neutron absorption the Th232 and the decay of Th233 will be extraction from 99% of the thorium and the natural U in thorium by MnO2 precipitations. The Pa233 will then be allowed to decay to U233 which in turn will be… more

The Machinability of Beryllium

Description: The following report investigates the isolation of the cause of the unusual tool-wear rates found in machining beryllium as attributed to an inherent characteristic of beryllium, or an effect of inclusions in beryllium, as well as the evaluation of the comparative machinability of the various types of beryllium.

Radiocarbon from Pile Graphite; Chemical Methods for its Concentration

Description: Abstract. Samples of pile graphite, irradiated in a test-hole at Hanford for 15 months, have been assayed for radioactive C14, yielding 0.38 ± 0.04 microcuries per gram. At this level of activity, the pile graphite contains very valuable amounts of C14. The relation between the above assay and the probable average assay of pile graphite is discussed, and it is concluded that the latter is almost certainly above 0.3 uc/ gram. Controlled oxidation of this graphite, either with oxygen at ~ 750°C,… more

Li⁶ and Li⁷ (n. 2n) Cross Sections at 14.1 Mev

Description: Abstract: "An absolute measurement of the 14.1-Mev (n, 2n) cross sections of Li-6 and Li-7 has been made using the large scintillator technique, resulting in cross sections in barns of 0.070 +/- 0.006 and 0.056 +/- 0.005 for Li-6 and Li-7, respectively."

The First Crystallographic Data for Curium Compounds

Description: Abstract: "X-ray powder patterns of two curium compounds, the trifluoride and the oxide, have been obtained, using sub-microgram specimens. The fluoride prepared by precipitation from aqueous solution with HF is isomorphous with NdF3. Treatment of CmF3 with F2 (g, 1 atm.) did not convert it to CnF4 or higher fluoride. Air ignition of curium oxalate gave a compound having a cubic lattice with a constant expected for Cm2O3 rather than for Cmo2. Due to the extremely high level of gamma and x-radia… more

K [infinity] in Uranium - Water Lattices

Description: This report follows experiments on K[infinity], measuring the element for several red sizes, enrichments, and water-to-uranium volume ratios-(1, 2), by making use of the relation k[infinity] = 0M-[2]B-[2] (M-2 = migration area, B = buckling). The purpose of this report is to compare the experimental data for k[infinity] with values calculated from the four-factor formula k[infinity] = [eta][epsilon]pf.
