Abstract: "This quarterly report, ARF 1194-10, covers the work performed in the time period December 15, 1961 to March 14, 1962, on Contract No. AT(11-1)-578. In this period, Phase II, the detailed evaluation of various fields of radioisotope research, has been extended. Preliminary results on the use of radioisotopes in the industrial applications, apparatus and techniques, and metallurgy categories are presented. These preliminary studies indicate the quantity of research, growth rates, and specialized areas of interest in various countries of the world. More detailed evaluations of these categories will be presented in the final report."

Report discussing a studies regarding "imaging qualities and the thermal neutron and gamma-ray sensitivities of several neutron imaging detectors".

The following report is one of a series of quarterly reports following the progress and development of improved zirconium alloys for service in superheated water and steam. This report covers the period between January 1 to March 31, 1962 and was conducted by the United States and the European Atomic Energy Community (EURATOM). The major effort in this period has been devoted to ascertaining and evaluating corrosion behavior of 75 ternary compositions.

This technical report describes a pulse height converter that employs the R.F. vernier method. This particular converter has been developed for use with the pulsed beam facility of the BNL Van de Graaff. This report then details a number of tests of the converter made using a RIDL model 34-12, 400-channel analyzer. The report includes 6 figures and 4 circuit diagrams to accompany the findings.

This technical report seeks to ascertain which amine species cause the synergistic effect exerted by tri-n-octylamine (TNOA) on the solvent extraction of thorium by TTA, the nature of the species formed, and the values of the equilibrium constants involved. This report also includes 2 figures and 2 tables to accompany the findings.

This technical report reviews the general purposes and immediate goals of the Heat Transfer Group at BNL's study of the heat transfer characteristics of alkali metals with phase change in forced convective flow. This report also presents a brief description of the design and development of the test loop. Figures detailing findings accompany the report.

Abstract: "Theoretical equations have been derived for calculating heat transfer coefficients for fluids flowing through concentric annuli for the following two cases: (A) constant and equal heat fluxes from both walls, and (B) constant, but unequal, heat fluxes from the walls, with equal wall temperatures at a given axial position along annular channel. In the derivations, the conditions of fully-established flow, and independence of physical properties with temperature variation across the flow channel, were assumed. The only geometrical parameter in this general case is the radius ratio r2/r1, and in the study it was varied from 1.0 to 10.0."

This report investigates the Szilard-Chalmers reaction in a number of crystalline compounds with a special effort made to maintain a low temperature during bombardment, storage and dissolution.

From abstract: "The effects of a number of substances that depress protoheme formation and affect free protoporphyrin production in duck erythrocytes in vitro were measured."

Technical report investigating the solvent extraction of thorium. The solvent extraction of thorium by the chelating agent, thenoyltrifluoroacetone (TTA), has proved to be a very effective tool for studying the complex ion chemistry of thorium. This study led to the establishment of the existence of aqueous complexation by the chelating agent.

Technical report outlining the plan to develop the Brookhaven chemonuclear in-pile test loop because the interest in utilizing reactor radiation energy (fission-fragment recoil and neutron-gamma) for production of chemicals has developed to the point where a loop to study chemonuclear system in a reactor under dynamic conditions is necessary.

Study comparing high resolution autoradiographic techniques using labeled DNA precursors and chemical methods of comparing mitotic indexes to evaluate tissue responses under continuous irradiation.

Technical report outlining preliminary work on a new technique of isotopic dilution analysis useful in the measurement of the radiogenic argon content of rocks or mineral samples in age determination.

Technical report defining "the information needed in order to use the mitotic index for computation of the time parameters of catenated cytologic compartments such as exist in hemopoiesis"--from introductory paragraph.

This report discusses the tryptic hydrolysis of heat-denatured sperm whale myoglobin resulting in two groups of peptides which accounts for the amino acid residues in the parent protein molecule.

This report reviews aspects of experimental and clinical research performed in the investigation on the pathogenesis and recovery of bone marrow injury caused by total body irradiation.

Technical report regarding the evaluation of body burdens of radionuclides in large populations in a large-scale survey.

This report, presented at the annual meeting of the Gerontological Society on November 10, 1961, expands on the research of Becquerel and Curies radioactive isotopes in medicine.

From introduction: "The over-all objective of the present study was to determine the nature and extent of the present study was to determine the nature and extent of the corrosion of these materials under a variety of such storage conditions and to determine the ability of several potential protective coatings to retard this corrosion."

The design status of the Experimental Fast Ceramic Reactor (EFCR) is described for the period up to October 31, 1961. The primary purpose of the facility is to study the dynamic behavior of a fast ceramic reactor, including the experimental demonstration of the effectiveness of the Doppler coefficient in limiting the power excursion following a rapid insertion of reactivity.

"The electrical conductance of CoCl2 and CoBr2 from 10−4 to 10−1 mol/l over the temperature range 0–35°C is reported. The effects of water as trace impurity, and the halide common ion effect on conductance are examined. The properties of these solutes are also examined using spectrophotometry and transport numbers. Crystalline “solvated” compounds, of empirical formulae [CoX2(CH3CN)3]x can be separated from the saturated solutions. The magnetic susceptibilities of the crystalline substrates are in accord octahedral and tetrahedral symmetry for the cationic and anionic species in these “solvates”, the bonding in both being the spin-free type for divalent cobalt. From the optical properties of the solutions it is apparent that the “anomalous” properties of these electrolytes can be understood in a series of simultaneous processes under Mass-Law control, in which CoX2, CoX42−, Co(CH3CN)62+ and [Co(CH3CN) 62+CoX42−]° are predominant."

This report examines the "vitamin B12 binding capacity of leukocytes obtained from three normal subjects and 19 persons with various hematologic disorders."

This phase of the program is concerned with irradiation of fuel assemblies to determine central temperature limitations.

The validity of the nuclear track emulsion technique for fast-neutron dosimetry is examined in the exposure of a human phantom to PuBe neutrons, Semiautomatic track scanning and high-speed data analysis obviate the major disadvantages of emulsion dosimetry, and allow the absolute differential proton track energy spectrum at various locations in the phantom to be obtained without a serious cost in time. From this are calculated the total absorbed local tissue dose due to proton recoils and the local thermal neutron intensity during irradiation.
