Naa Ceramic Analysis

For many elements naa offers sensitivities that are superior to those possible by any other technique.

Naa ceramic analysis.

Neutron activation analysis naa is a non destructive analytical method commonly used to determine the identities and concentrations of elements within a variety of materials. We report the results of an analysis of chemical composition data obtained from neutron activation analysis naa of pottery sherds originating from three late developmental sites in the southern tewa basin of the nrg. The resulting data based on bulk analysis of the clay and any inclusions can help to identify ceramic vessels likely produced using similar resources. The probability of a neutron interacting with a nucleus is a function of the neutron energy.

The application of neutron activation analysis naa to investigate archaeological problems began in the mid 1950s when scientists at brookhaven national laboratory sayre and dodson 1957 recognized its potential for relating artifacts to source materials through their chemical signatures. 58 fe is a stable isotope of iron while 59 fe is a radioactive isotope. Neutron activation analysis naa is a powerful quantitative analytical technique with applications in a range of fields including archaeology. Neutron activation analysis naa is one of the most sensitive analytival techniques used for qualitative and quantitative multi element analysis of major minor and trace elements in samples from almost every conceivable field of scientific or technical interest.

The use of neutron activation analysis naa to characterize archaeological ceramics has a long history and is now a standard method for determining provenance. Unlike many other analytical techniques naa is based on nuclear rather than electronic transitions. While compositional analysis of the ceramic pastes by naa and la icp ms demonstrates that there are three distinct compositional groups for the lead glazed ceramics from the region la icp ms data of the major minor or trace elements of the glazes do not distinguish those same compositional groups. Comparison of the glazed ceramic naa data to.

The cares ceramic analysis and reliability evaluation of structures program they developed offers a cost effective means for simulating tests of ceramic components. It enables a designer to test a variety of configurations for probability of failure and to adjust the structure s geometry to minimize the predicted failure or maximize durability. This probability is referred to as the capture cross. The gamma rays emitted during the decay of the 59 fe nucleus have energies of 142 4 1099 2 and 1291 6 kev and these gamma ray energies are characteristic for this nuclide.

Moreover the continued. Due to its outstanding sensitivity accuracy precision and versatility the technique is a suitable method for analysing many different types of archaeological material.
