The International Atomic Energy Agency (IAEA) has many projects and activities supporting the utilization of nuclear research reactors for neutron activation analysis (NAA). Globally the number of operating nuclear research reactors has been in decline since about 1975. This contrasts with the situation in developing countries where the numbers show a modest increase over the same period. This paper reviews the current status of NAA as seen from the particular perspective of IAEA programs involving studies of biological and environmental specimens. Some of the areas in which NAA is maintaining its role as a competitive technique are briefly reviewed.
