Neutron source progress report

Neutron source progress report

Date: December 1, 1948
Creator: Richmond, J.L.
Description: In this report progress is reported on the production of the postum-beryllium neutron sources and the postum-fluoborate neutron sources. A brief discussion is given for each. Results are given of the efficiency of the postum-fluoborate source and its comparison with Std. 9 and Al-1. This source was shipped to Los Alamos on December 16, 1948.

The excretion of hexavalent uranium following intravenous administration. II, Studies on human subjects

The excretion of hexavalent uranium following intravenous administration. II, Studies on human subjects

Date: June 25, 1948
Creator: Bassett, S.H.; Frankel, A.; Cedars, N.; VanAlstine, H.; Waterhouse, C. & Cusson, K.
Description: Tracer studies employing uranium enriched in the isotopes U{sup 234}, U{sup 235} have been carried out in six human subjects; four males and two females. The uranium, 6 micrograms to 70 micrograms per kilogram of body weight was given intravenously in the hexavalent state as uranyl nitrate. Each individual of the series received a single injection of the metal except for one who was given two widely spaced doses. The first of these was when his condition was normal and the second after an acidosis had been produced by ingestion of ammonium chloride. Renal function tests including urinary catalase, protein, amino N to Creatinine N ratio and clearances of mannitol and p-aminohippurate were done before and after administration of uranium. Only at the 70 microgram per kilogram level in Subject 6 was there a slight rise in urinary catalase and protein suggesting that tolerance had been reached. The excretion of uranium was mainly in the urine, where from 70 to 85% of the administered dose appeared in the first twenty-four hours. Urine of the second twenty-four hours contained about 4% and the third twenty-four hour urine, 1.5% of the administered dose. Detectable amounts were excreted for at least two weeks.

Density of metallic polonium (Information Meeting Paper No. 13)

Density of metallic polonium (Information Meeting Paper No. 13)

Date: November 9, 1948
Creator: Haring, M.M.
Description: This document is the report from a November 1948 meeting at Mound Laboratory on the measurement of the density of metallic polonium. Four determinations of the density of Polonium at 25 degrees C have been made. These values are 8.69 gm/cc, 9,34 gm/cc (twice) and 9.20 gm/cc. The probable error was 2%. The material used in the first determination was not subjected to a preliminary purification, which makes the value obtained doubtful. In this instance, production foils were used without a separation from their more volatile constituents. The difference in the reported value from that which appears in the Ad Interim Report is due to a recalculation based on the latest information on the physical constants of polonium. The value of using pure material and knowing the physical properties of polonium are clearly indicated.
