The entrance into normal service in 1958 of the first reactor in Japan, the JRR-1 at the Tokai Research Establishment of the Japan Atomic Energy Research Institute, was followed by rapid progress in developmental studies in Japan in neutron activation analysis, mainly with the use of thermal neutrons. Applications are being developed, especially those that bring out the particular merits of this method, such as high sensitivity and high selectivity, which make it extremely attractive as a tool for microanalysis. Uses have now extended to a wide field of applications including metallurgy, geochemistry, petrochemistry, biochemistry, biology, medicine, agriculture, hydrology, and archeology. Non- destructive activation analysis utilizing the nuclear characteristics of short- life isotopes has found unique applications in the examination of precious and irreplaceable specimens such as in archeological work. Techniques of simplified and rapid analysis are also being established for dealing with large numbers of samples successively on a routine basis. Other developments mentioned in activation analysis include work utilizing fast neutrons (14 Mev) from neutron generators, and charged particles from accelerating machines such as cylotrons. This opens up new possibilities in the analysis of light elements, difficult to determine with thermal neutron. (JAIF)
