Methods of neutron activation analyses, described in many scientific books and papers, have been frequently used in different analyses of soils and rocks. In studies of aquatic ecosystems, neutron activation methods have been used in sediments and seawater (for example, Kamel et al., 1987; Fernandes et al., 1993; Cardoso and Godoy, 1995).

Neutron activation analysis is a physical tool by which various elements may be quantitatively determined, often with an extreme degree of sensitivity. Hitherto, factors of cost and distance involved in securing a neutron source have apparently precluded extensive biologic usage but, with the more recent availability of smaller nuclear reactors, more ...

AbstractIn Recent Years there has been an increasing demand for materials of very high purity for uses on an industrial as well as a laboratory scale. This has provided an impetus to the development of analytical methods for the determination of minute quantities of impurities.

Neutron activation in interrupted neutron beams
Applied Radiation and IsotopesNeutron activation of activation targets in neutron beams with interruptions is studied. A simple and robust formalism for determining the number of activated atoms in neutron activation measurement despite beam interruptions is derived. Two simplified methods for correcting for the decay of produced nuclei in the activation target during beam ...

Neutron Activation Analysis with Low Neutron Flux
IEEE Transactions on Nuclear Science, 1986Procedures are described for identifying and determining concentrations of trace impurities in minerals by means of neutron activation analysis with low neutron flux and standard gamma measurement equipment. Techniques developed in this work may be of use to those involved with the ever increasing need for mineral assays and for pollutant measurements,

Neutron Activation Data for Neutron Interrogation
AIP Conference Proceedings, 2005Various schemes have been proposed for neutron interrogation of packages, luggage, or containers with the intent of locating concealed contraband items such as conventional explosives, drugs, or restricted special nuclear materials. Relatively intense and energetic neutron sources are usually required in these applications in order to penetrate the ...

Neutron flux uniformity in in vivo neutron activation analysis
Physics in Medicine & Biology, 1976Horowitz et al. (see ibid., vol.21, p.306, 1976), have recently criticized published work on in vivo neutron activation analysis for an implicit assumption that radiative capture cross-sections are everywhere negligible except at thermal energies, and have stated that this has led to undue emphasis being placed on thermal neutron flux uniformity in ...
