Urine Analysis for Tritium Oxide (open access)

Urine Analysis for Tritium Oxide

This report analyzes a procedure based on the production of acetylene from the active water, with subsequent measurement of the ionization caused by the tritium beta particle. This eliminates the troublesome absorption on the chamber walls when hydrogen is used, and provides a rapid method for the preparation of the urine samples.

A Rapid Colorimeric Method for the Determination of Phosphate in Uranium Waste Solutions (open access)

A Rapid Colorimeric Method for the Determination of Phosphate in Uranium Waste Solutions

Report discussing tests of a new colorimetric method. From abstract: "A colorimetric method, which is a modification of the classical phosphomolybdic acid method, has been developed for the determination of phosphate in synthetic uranium waste solutions...The chief advantage of the method, over those presently included in HW Manuals, is the rapidity with which determinations may be carried out."

The Identification and Determination of Trace Amounts of Rare Earth Elements in Graphite by Neutron Activation (open access)

The Identification and Determination of Trace Amounts of Rare Earth Elements in Graphite by Neutron Activation

Abstract: "A method is described for the identification and quantitative determination of trace amounts of rare earths in graphite by measurement of the energies and decays of the activities induced by neutron irradiation. The specific rare earth elements identified are europium and samarium. During the development of this method, the half-lives of Eu-152 and Sm-153 were determined. These are reported as 9.32 +/- 0.04 hours and 46.34 +/- 0.23 respectively."

Exploratory Scavenging Studies for the Decontamination of Redox Solutions (open access)

Exploratory Scavenging Studies for the Decontamination of Redox Solutions

From introduction: "This report is concerned with exploratory experiments designed to studies the efficiency of a number of scavengers for zirconium and niobium adsorption and to provide preliminary information on the best conditions to employ on the most satisfactory of those scavengers studied, namely Super Filtrol FO. The data in this report include data obtained through October, 1949, and are by no means considered to be final. The investigation is currently being actively continued."

Effect of Temperature on Beta-Ray Measurements (open access)

Effect of Temperature on Beta-Ray Measurements

Summary: "This report investigates photographic methods of measuring beta radiation and includes a study of temperature effects on these measurements. Experimental data are submitted to show that an increase in film temperature before and during beta irradiation causes a definite increase in density for the same dosage. Recommendations drawn from experience gained in the experimental works are offered."

The Determination of Total Plutonium in the Presence of Aluminum (open access)

The Determination of Total Plutonium in the Presence of Aluminum

Introduction: "The adoption of aluminum nitrate as salting agent in the Redox process made it imperative that a method be available for determining plutonium in the presence of aluminum. However, large amounts of aluminum have been found to interfere with the determination of plutonium by the lanthanum fluoride procedure. Previous attempts to increase the accuracy of the lanthanum fluoride method, by precipitating LaF3 from 4 M HF (rather than 2 M), have been successful only when the initial plutonium level was high."
