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 Analysis (NAA) is a quantitative and qualitative method of high efficiency for the precise determination of the number of main-components and trace elements in a sample. Together with other analytical methods, NAA has opened up new paths in geological research promoting the development of analytical databanks to check the theoretical

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).

The discovery of the neutron by Chadwick in 1932 is a relatively recent event in the history of science (see Heller, 1976). Soon after that discovery, neturons had been used to activate elements, and Bowen (1956) showed that neutron activation could be a highly sensitive method of analysis.

Discovery of neutron activation analysis
Applied Radiation and Isotopes, 2022It is well known that George Hevesy and Hilde Levi were the original discoverers of neutron activation analysis. However, there were many other researchers in Europe that firstly unknowingly and knowingly discovered the neutron, and others who experimented in neutron induced radioactivity.

Neutron activation analysis (NAA) possesses many merits such as high sensitivity, good accuracy and precision, small sampling quantity and multi-elemental analysis ability. In recent decades, conventional NAA has been combined with physical, chemical or biological separation procedures to meet the ever-increasing need for chemical species study.

Neutron activation analyis was first proposed as an analytical technique by von Hevesy and Levi in 1936. However, its successful application to geology (Gordon et al., 1968; Hertogen and Gijbels, 1971) had to await the commercial development of high-resolution germanium detectors during the 1960s to allow satisfactory analysis of the complex gamma ...
