Plutonium oxalate precipitation for trace elemental determination in plutonium materials

Determination of plutonium in human feces.

The toxic effects of plutonium on the human body depend on a considerable number of physical and biological factors. One of the most important biological factors is the rate of elimination of plutonium from the body. The ratio of fecal to urinary excretion of plutonium by the rat is of the order of 10: 1. This is, indeed, a favorable ratio. Preliminary information, however, indicates that the e...

Rapid method for plutonium-241 determination in soil samples

A simple and rapid procedure for the determination of plutonium isotopes in the environment is presented. The procedure combines alpha spectrometry, solvent extraction and liquid scintillation measurements to ensure that both alpha- and beta-emitting isotopes are determined. Of five tested extractants, bis-(2-ethylhexyl) phosphoric acid was found to be the best choice. The procedure was applied...

Toxicological Profile for Plutonium

Plutonium problems.

Contaminants in Fish From the icy waters of Boston Harbor to the warm waves of San Diego Bay, bottomdwelling fish suffer liver damage caused by chemical contaminants, according to researchers at the National Oceanic and Atmospheric Administration. But seafood lovers need not panic, because damaged specimens were captured primarily in urban waters where commercial fishing is prohibited, said Lyn...

Gamma Assay of Uranium and Plutonium 5 v. Analytical Methods and Automated Instruments for the Determination of Plutonium and Uranium

Progress continued on method development for the dissolution of difficult-to-dissolve materials, the automated analysis of plutonium and uranium, the preparation of plutonium materials for the Safeguard Analytical Laboratory Evaluation (SALE) Program, and the analysis of HTGR fuel and SALE uranium materials. The previously developed Teflon-container, metal-shell apparatus was applied to the dis...
