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 cavity-type ionization chambers with graphite walls that are used to measure heat dissipation in the graphite reflector of the MTR mock-up. Studies the relationship between the ionization occurring in the chamber and the heat generated in the surrounding graphite medium. [From Abstract]

Technical report covering work completed on the removal of radioisotopes from water using a calcium phosphate floc as a carrier. This research was performed as part of the Health Physics Waste Disposal Research Section work on the removal of small quantities of radioactivity from large volumes of water. [From Abstract]

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 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.

Technical reports outlining the controls for the Homogeneous Reactor Experiment (HRE); controls are divided into three principal groups. 1. Reactor. 2. Process or auxiliary. 3. Power generation. These are the classifications designating the primary functions of the controls. [From Introduction]

From introduction: "In this report we consider a few non-adiabatic processes. The types to be discussed will be limited because of two reasons: first, complete descriptions are available for some processes; second, as time goes on alternative injection methods undoubtedly will be discovered, so this list must necessarily be incomplete."

Cost estimates for two types of Th producing plants are offered. One utilizes Th(NO3)4 as raw material, the other uses monazite sand. Final processing schemes and plant designs are not fixed, so the estimates represent maximum costs. Recommendations for research and development of Th producing methods are given.

Abstract. a method of recovering thorium from slag from the bomb process of producing thorium has been developed. HCl and NaOH are the only chemicals required in quantity. Materials required for a representative slag are given.

Abstract Line spectra of vanadium, niobium, titanium, molybdenum and rhenium of sufficient intensity to allow detection at the 1–10 p.p.m. level can be excited in fuel-rich, oxy-acetylene flames. For the strongest lines of tungsten, the sensitivity of detection is 90 p.p.m. Weak lines of zirconium, hafnium, osmium, tantalum and uranium are also observed in these flames. Recordings of the spectra are given along with wavelength tables of the strongest lines.

Technical report that attempts to bring together the various chemical procedures which proved most useful in studying the results of cyclotron bombardment or small scale neutron bombardments of heavy element targets. The report is limited to the elements of the "actinide", or second rare earth series, starting with thorium and including the newly discovered elements of atomic number 95 and 96. Every attempt is made to include all details necessary so this report can serve as a practical laboratory guide. The report covers separation problems, time factors, and dealing with dangerously radioactive targets.

Report discussing the progress made on research concerning sluge-supernate acidification. This report focuses mainly on "'reverse strike' acidification and the observations of the physical characteristics of the test material," which was a synthetic incubated metal waste.

This report is part one of a series of two parts to a memorandum. The work discussed here presents the results of extensive calculations on the attention of gamma rays by shields of lead and iron.

Abstract: "The energy-dependence of the formation cross section of certain nuclides formed in fission of uranium and thorium has been studied. Excitation functions in the hundred-Mev region are given for Ni66, Zr97, Ag111, Ba131, and Ba139. Protons, deuterons, and alpha particles from the Berkeley 184-inch frequency modulated synchro-cyclotron were used to induce the activities."

From abstract: This investigation was conducted in order to develop a process whereby the most abundant zirconium ore, namely zircon, could economically be put into solution and purified adequately for use in hafnium separation processes employing liquid-liquid extraction. Secondary aims concerned the preparation of pure zirconyl chloride, zirconyl nitrate, zirconyl sulfate, and zirconium oxide from the zircon ore.

Report presenting data on the thermal conductivity of fuel element materials with short summaries.

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