RECOVERY OF Np$sup 237$ AND Pu$sup 238$ FROM IRRADIATED NEPTUNIUM OXIDE

Description: An ion exchange process was demonstrated for the recovery of Pu/sup 238/ from irradiated neptunium oxide. Three cycles of anion exchange proved adequate for the removal of fission products and for the separation of the neptunium and plutonium from each other. (auth)

CHEMICAL PROCESSING OF Pu$sup 23$$sup 8$

Description: Plutonium (principally Pu/sup 238/) was separated from neptunium, and both the plutonium and neptunium were purified from fission products and cations by a three-cycle anion exchange process. (auth)

Criteria for Preparing and Packaging Plutonium Metals and Oxides for Long-Term Storage

Description: This Standard provides criteria for packaging of plutonium metals and stabilized oxides for storage periods of at least 50 years. To meet the criteria, plutonium-bearing materials must be in stable forms and be packaged in containers designed to maintain their integrity both under normal storage conditions and during anticipated handling accidents.

Monthly Progress Report Heat Source Technology Programs September 1996

Description: This monthly report describes activities performed in support of Cassini fueled-clad production and studies related to the use of 238Pu02 in radioisotope power systems carried out for the Office of Special Applications of the U.S. Department of Energy (DOE) by Los Alamos National Laboratory (LANL). Most of the activities described are ongoing; the results and conclusions described may change as the work progresses.

Radionuclide Concentration in Soils and Vegetation at Low-Level Radioactive Waste Disposal Area G during 2005

Description: Soil samples were collected at 15 locations and unwashed overstory and understory vegetation samples were collected from up to nine locations within and around the perimeter of Area G, the primary disposal facility for low-level radioactive solid waste at Los Alamos National Laboratory (LANL). Soil and plant samples were also collected from the proposed expansion area west of Area G for the purpose of gaining preoperational baseline data. Soil and plant samples were analyzed for radionuclides that have shown a history of detection in past years; these included {sup 3}H, {sup 238}Pu, {sup 239,240}Pu, {sup 241}Am, {sup 234}U, {sup 235}U, and {sup 238}U for soils and {sup 3}H, {sup 238}Pu, and {sup 239,240}Pu for plants. As in previous years, the highest levels of {sup 3}H in soils and vegetation were detected at the south portion of Area G near the {sup 3}H shafts; whereas, the highest concentrations of the Pu isotopes were detected in the northern and northeastern portions near the pads for transuranic waste. All concentrations of radionuclides in soils and vegetation, however, were still very low (pCi range) and far below LANL screening levels and regulatory standards.

Mound Laboratory plutonium study: Presentation to the scientific review panel

Description: This paper describes the Mound plutonium study. The objectives of the project were to evaluate the inventory of plutonium 238 in the environment at Mound, determine the source, and alleviate potential health hazards. Analysis of soils, water, vegetation, fishes, and runoff were performed.

Human radiation studies: Remembering the early years. Oral history of Health physicist William J. Bair, Ph.D., October 14, 1994

Description: This report is a transcript of an interview of William J. Blair by representatives of the US DOE Office of Human Radiation Experiments. Dr. Blair was selected for this interview because of of his participation in the University of Rochester Atomic Energy Project and for his radiological inhalation research at Hanford Site. After a brief biographical sketch Dr. Blair discusses his remembrances on a wide rage of topics. Discussions include his graduate studies at Rochester University, use of human subjects at Rochester, his inhalation studies, his limited involvement with human studies, differing biological effects of plutonium 238 and 239, emissions from proposed nuclear-propelled aircraft, cancer research, cleanup at Nevada Test Site and Marshall Islands, impact of Langham studies to understand Plutonium exposure, and AEC controversies and colleagues.
