AbstractProcedures and results of an experimental investigation of 239Pu and 241Am contamination in the environs of the Rocky Flats plutonium plant and elsewhere in the greater Denver area are presented and discussed. Measurements of 239Pu and 90Sr in the top 1 cm surface layer of soils show that in 

Toxicity of plutonium and some other actinides

A biochemist takes stock of the present state of knowledge of the health effects of radioactive nuclear fission products; he concludes that the dangers of a plutonium economy may be greater than we...

Behavior of Plutonium and Americium in soils.

The depth profiles and the particle size dependencies of the distributions of 239, 240Pu and 241Am in soil have been studied in comparison with those of 137Cs to obtain information on clarifying

Plutonium hazard in respirable dust on the surface of soil.

It is prposed that this method of evaluation defines more precisely the potential health hazard from the respirable fraction of plutonium-contaminated soils.

Contributions of Rocky Flats releases to the total plutonium in regional soils.

Although the RFETS contribution to total plutonium at the offsite locations ranged from 24-90%, the overall inventory was relatively small and total inventory estimates, for one transect, based on 239,240Pu and from 240Pu:239Pu atom ratio measurements were not significantly different.

Determination of Pu, Am, U and Cs in large soil samples in the vicinity of the USDOE Waste Isolation Pilot Plant

The determination of actinides in environmental soil and sediment samples are very important for environmental monitoring. A rapid actinide separation method has been developed and implemented that

Comparative distribution of 241 Am and 239,240 Pu in soils around the Rocky Flats Environmental Technology Site.

Comparison with earlier studies indicate that the plutonium depth profile has not changed significantly over the last 25 y, and 241 Am concentrations can be used to infer 239,240 Pu by counting the 241 Am via gamma spectroscopy.

PLUTONIUM DISTRIBUTION IN ROCKY

Plutonium concentrations in Rocky Flats soil were inversely proportional to distance from the plutonium source, to depth of the sample, and to particle size of sieved soil samples. Coefficients of
