A neutron-induced prompt gamma-ray analysis (PGA) has become widely utilize
d due to the improved analytical sensitivities and detection limits especia
lly by using low energy guided neutron beams. Current studies on the low en
ergy neutron guided beam PGA are reviewed. Historical backgrounds, current
analysis systems, advantages when compared with conventional NAA, standardi
zation for elemental determination and analytical applications in JAERI of
the guided beam PGA are described.
