Abstract

From 1979 to 1989, approximately 25,000 Post Northern Marshall Islands Radiological Survey (PNMIRS) samples were collected, and over 71,400 radiochemical and gamma spectroscopy analyses were performed to establish the concentration of {sup 90}Sr, {sup 137}Cs, {sup 241}Am, and plutonium isotopes in soil, vegetation, fish, and animals in the Northern Marshall Islands. While the Low Level Gamma Counting Facility (B379) in the Health and Ecological Assessment (HEA) division accounted for over 80% of all gamma spectroscopy analyses, approximately 4889 radiochemical and 5437 gamma spectroscopy analyses were performed on 4784 samples of soil, vegetation, terrestrial animal, and marine organisms by outside laboratories. Four laboratories were used by Lawrence Livermore National Laboratory (LLNL) to perform the radiochemical analyses: Thermo Analytical Norcal, Richmond, California (TMA); Nuclear Energy Services, North Carolina State University (NCSU); Laboratory of Radiation Ecology, University of Washington (LRE); and Health and Ecological Assessment (HEA) division, LLNL, Livermore, California. Additionally, LRE and NCSU were used to perform gamma spectroscopy analyses. The analytical precision and accuracy were monitored by including blind duplicates and natural matrix standards in each group of samples analyzed. On the basis of reported analytical values for duplicates and standards, 88% of the gamma and 87% of the radiochemical analysesmore »« less

Northern Marshall Islands Radiological Survey: a quality-control program for a radiochemical analyses

Technical Report Jennings, C; Mount, M

More than 16,000 radiochemical analyses were performed on about 5400 samples of soils, vegetation, animals, fish, invertebrates, and water to establish amounts of /sup 90/Sr, /sup 137/Cs, /sup 241/Am, and plutonium isotopes in the Northern Marshall Islands. Three laboratories were contracted by Lawrence Livermore National Laboratory to perform the radiochemical analyses: Environmental Analysis Laboratory (EAL), Richmond, California; Eberline Instrument Corporation (EIC), Albuquerque, New Mexico; and Laboratory of Radiation Ecology (LRE), University of Washington, Seattle, Washington. The analytical precision and accuracy were monitored by regularly including duplicate samples and natural matrix standards in each group of about 100 samples analyzed. Basedmore »« less
Radiological survey of plants, animals, and soil at Christmas Island and seven atolls in the Marshall Islands. Progress report for 1974--1975

Technical Report Nelson, V

The Division of Operational Safety or DOS (now Safety Standards and Compliance) portion of the Laboratory of Radiation Ecology (LRE) Pacific Radiocology Program (formerly Johnston Atoll Program) began on 1 July 1974 and is continuing. The purpose of this program is to determine the kinds and amounts of radionuclides distributed in the foods, plants, animals, and soil of the Central Pacific, especially the Marshall Islands. Five field trips were conducted for this program between April 1974 and August 1975, and about 600 samples were collected. Results of the analyses indicate that /sup 90/Sr and /sup 137/Cs are dominant in themore »« less
Estimation of Radiation Doses in the Marshall Islands Based on Whole Body Counting of Cesium-137 (137Cs) and Plutonium Urinalysis

Technical Report Daniels, J; Hickman, D; Kehl, S; ...

Under the auspices of the U.S. Department of Energy (USDOE), researchers from the Lawrence Livermore National Laboratory (LLNL) have recently implemented a series of initiatives to address long-term radiological surveillance needs at former nuclear test sites in the Republic of the Marshall Islands (RMI). The aim of this radiological surveillance monitoring program (RSMP) is to provide timely radiation protection for individuals in the Marshall Islands with respect to two of the most important internally deposited fallout radionuclides-cesium-137 ({sup 137}Cs) and long-lived isotopes 239 and 240 of plutonium ({sup 239+240}Pu) (Robison et al., 1997 and references therein). Therefore, whole-body counting formore »« less

Development of a Quantitative TaqMan{trademark}-PCR Assay and Feasibility of Atmosphoric Collection for Coccidioides Immits for Ecological Studies

Technical Report Daniels, J; Wilson, W; DeSantis, T; ...

Understanding and then modeling the complex relationships between environmental, climatological, and biological systems can present great opportunities for developing effective strategies to prevent outbreaks of environmentally linked infectious disease. For example, a report from the American Academy of Microbiology (Rose et al., 2001) points out that including climatic signals and ecological triggers into the decision making process for disease management, is going to be essential for developing a proactive approach for protecting public health, and circumventing the practice of having to wait for clinical cases to appear before any action is taken. To meet this grand challenge, specific and sensitivemore »« less

Correction to Account for the Isomer of ⁸⁷Y in the ⁸⁷Y Radiochemical Diagnostic

Technical Report Hayes-Sterbenz, Anna; Jungman, Gerard

Here we summarize the need to correct inventories of ⁸⁷Y reported by the Los Alamos weapons radiochemistry team. The need for a correction arises from the fact that a 13.37 hour isomer of ⁸⁷Y, that is strongly populated through (n, 2n) reactions on ⁸⁸Y and isomers of ⁸⁸Y, has not been included in the experimental analyses of NTS data. Inventories of ⁸⁷Y reported by LANL’s weapons radiochemistry team should be multiplied by a correction factor that is numerically close to 0.9. Alternatively, the user could increase simulated values of ⁸⁷Y by 1.1 for comparison with the original method for reportingmore »« less
