In conventional neutron activation analysis
(NAA), a Ge detector is used to measure these gamma rays for qualitative and quantitative analysis.
They describe glass as a material, including its physico-chemical properties, raw materials, methods, physical processes, and materials for providing colors and tints, and how the composition of European glass has evolved; mass spectrometric methods for provenancing studies; and methods for determining the elemental composition and other properties of glass samples using energetic electromagnetic radiation, including X-rays for elemental glass analysis at the major to trace level, for speciation, and for 3D imaging, methods that use synchrotron radiation, forms of electron microscopy, analyzing minute glass fragments or entire vessels using ion beam methods, and instrumental neutron activation analysis
Environmental variation of arsenic levels in human blood determined by neutron activation analysis
All the samples were sent to Actlabs Laboratories of Ancaster, Ontario, for multi-element determination by ICP-MS and neutron activation analysis
Based on Prompt Gamma Neutron Activation Analysis
technology, N-SCAN uses energetic neutrons to cause nuclear reactions within the atoms of a material.
A second series of assays on the same samples by Neutron Activation Analysis
is in progress in order to confirm the anomalies detected by ICP-MS.
The compositional results from neutron activation analysis
and thin-section petrology of Roman pottery can feed directly into hypothetical models of production and distribution, and to a model for the place of that industry in the Roman economy (Peacock 1982; Peacock & Williams 1986; Evans 1989).
Called "prompt gamma neutron activation analysis
," or PGNAA, the technology goes Superman one better in its ability not only to see through solid materials such as soil or concrete but also to provide detailed information on what they contain.
