Carcinogenesis by Radioactive Substances

Description: Knowledge of the potential dangers of exposure to radioactive substances and the institution of proper safety precautions have helped to reduce accidental exposures to radioactive substances. In the following technical report we shall review briefly carcinogenesis in man by naturally occurring and artificially produced radioactive substances, the lung cancer problem in miners, the development of bone tumors in luminous dial painters and in patients treated with radium-containing nostrums, and t… more

A Cloud Chamber Study of the Secondary Particles from Locally Produced Penetrating Showers

Description: The present experiment was undertaken as an attempt to throw more light on the decay processes that had been observed prior to the summer of 1952, as well as to investigate any new decay processes that might manifest themselves. The source of high energy primary particles was to be the cosmic ray beam, so a detector of locally produced high energy penetration showers was used. In order to be able to detect effectively low energy photons and low energy secondaries from particles reaching the end… more

A Comparison of the Neutron Yields from Low-Voltage Sources

Description: The description of the thick-target neutron yields from the D(t,n)He4 and the D(d,n)He3 reactions is calculated as a function of the energy of the bombarding particles. For 60-kev particles the ratio is 108. I increases to 168 at 100 Kev and to 194 for 120-kev particles. A qualitative discussion of the yields from various deuterium target leads to the conclusion that the greatest yield would come from the target which has the lowest stopping cross section per deuterium atom.

Correlation of Polarographic Walf-Wave Potentials With Nuclear Magnetic Resonance "Chemical Shifts"

Description: "Since nuclear magnetic resonance ''chemical shifts'' are considered to be good measures of electron densities in molecules, the extent to which they can be correlated with the polarographic half-wave potentials of organic compounds has been surveyed. To extend the applicability and interpretation of the proposed correlation, parallel correlation of E, with Hammett's sigma and Taft's sigma parameters were made, since both of the latter are also regarded as indication of electronic distribution … more

Corrosion of INOR-8 and Inconel Dissolver Components of the Fluoride-Volatility Process

Description: The corrosion of INOR-8 and Inconel dissolver components used in the fluoride volatility process for the dissolution of zirconium with anhydrous HF in molten salts was investigated. Ten dissolution runs were made using simulated subassemblies formed from Zircoloy-2. The dissolver and components were made from INOR-8. Both the dissolver vessel and draft tube were examined several times during the series of runs. The solids which formed at different areas in the system were also analyzed. The res… more

Corrosion Resistant Brazing Alloys for Zircaloy

Description: "This is a progress report covering the first year of work on ARF Project B 080, "Corrosion Resistant Brazing Alloys for zircaloy". the objective of the work reported is the development of filler metals suitable for the brazing of zirconium base alloys in cases where the service environment of the brazement is to be high temperature water. The experimental approach has been necessarily a somewhat empirical one. During this first year of work some forty experiments of simple design for corrosion… more

The Decomposition of Solid Barium Nitrate by Gamma Rays

Description: There was considerable disagreement between results obtained by early investigators who studied the interaction of ionizing radiations with solid nitrates. It was thought worthwhile, therefore, to extend their work and to make certain that reproducible results were being obtained. It was expected that the nitrite ion and oxygen would be found in equivalent amounts in the irradiated samples. Four measurements of nitrite ion and oxygen indicate that the decomposition of barium nitrate by gamma r… more

Detection of Airborne Beryllium Dust : Monthly Report Covering the Period from May1 to June 1, 1955

Description: During this period a prototype gamma ray detection system was assembled and data was obtained on samples of beryllium salts on filter paper under a variety of conditions. Ordinarily either a scaler-register combination or the CRM-recorder combination would be sufficient for obtaining data. Both units have been used here in order to utilize the particular advantages of each system. The scaler-register unit was employed for obtaining precise data over short intervals while the CRM-recorder was us… more

The Determination of Decontamination Factors for Radioisotopes Through Lithium Hydroxide Resin. Section I. Second Performance. Core I, Seed 1. Test Results DL-S-277-S, RNI-22

Description: The purpose of the test was to obtain data on the decontamination factors for Cesium-136, Cesium-137, Strontium-92, one hour gross iodine and Iodine-131. This data will be used to determinate efficiency of lithium hydroxide resin for removing radioactive cations and anions. The denomination factors for a particular demineralizer using lithium hydroxide resign were found to vary for different radioisotopes. This variation was from 2.3 for Cesium136 to 77,000 for gross iodine.

Determination of Flux Levels in Neutron Detector Wells. Section II. First Performance. Core I, Seed 1. Test Results DL-S-242, T-641311

Description: The purpose of the test was to determine the neutron flux level in a BF3 counter well during the second performance of DL-S-225. The measured activity of the irradiation brass bolt was due entirely to the radioactive decay of Zn65. The thermal neutron flux in the BF3 counter well during the second 1000 hour run was calculated to be 2.5 x 10(9) neutrons/cm2 sec.
