Geological and inorganic materials
Autor: L. L. Jackson, D. M. McKown, J. E. Taggart, P. J. Lamothe, F. E. Lichte
Publikováno v: Analytical Chemistry. 59:197-212
The current review covers the literature reported from November 1984 to October 1986. This review covers the analytical techniques that are currently applied to the analysis of geological and inorganic materials. The authors have tried to highlight w

Epithermal neutron activation analysis using a boron carbide irradiation filter
Autor: William D. Ehmann, J. Brückner, D. M. McKown
Publikováno v: Journal of Radioanalytical Chemistry. 57:491-502
The use of boron carbide as a thermal neutron filter in epithermal neutron activation (ENAA) analysis has been investigated. As compared to the use of a cadmium filter, boron provides a greater reduction of activities from elements relatively abundan

Rapid measurement of selenium in biological samples using instrumental neutron activation analysis
Autor: D. M. McKown, J. S. Morris
Publikováno v: Journal of Radioanalytical Chemistry. 43:411-420
A rapid instrumental system for measuring selenium via 17 second77mSe has been applied to the analysis of a wide variety of biological specimens encountered in biomedical research. The reliability and versatility of the method is documented for serum

Determination of uranium concentration in water by liquid anion exchange-delayed neutron analysis
Autor: R. A. Zielinski, D. M. McKown
Publikováno v: Journal of Radioanalytical and Nuclear Chemistry Articles. 84:207-212
Dissolved uranium is selectively removed from 11 of filtered, acidified water using a liquid anion exchange resin (Amberlite LA-1) dissolved in 10 ml of purified kerosene. The organic phase is then analyzed by a standard delayed neutron counting tech

Instrumental Activation Analysis of Meteorites Using Gamma-Gamma Coincidence Spectrometry
Autor: W. D. Ehmann, D. M. McKown
Publikováno v: Analytical Letters. 2:49-60
A non-destructive procedure for the determination of iridium, sodium, nickel, cobalt, and scandium in a single meteorite sample is presented. The method utilizes neutron activation followed by gamma-gamma coincidence spectrometry. Iridium abundances

Allende Meteorite : Some Major and Trace Element Abundances by Neutron Activation Analysis
Autor: D. M. Mckown, William D. Ehmann, J. W. Morgan, T. V. Rebagay, R. A. Nadkarni, D. E. Gillum, D. L. Showalter
Publikováno v: Nature. 224:789-791
THE Allende (Chihuahua, Mexico) meteorite of February 8, 1969 (ref. 1 and unpublished report of R. S. Clarke, jun., E. Jarosewich, B. Mason and J. Nelen), is of great interest because it belongs to a group of relatively rare carbon containing meteori
