Applications of nuclear analytical methods in the life sciences as exemplified by recent research programs of the IAEA.

More than 300 research nuclear reactors are presently in operation in 56 countries, most of which are suitable for neutron activation analysis (NAA). Typical applications in the life sciences are exemplified by recent research programs of the IAEA involving the participation of institutes in 47 countries. Topics of interest include applications of NAA (together with XRF and PIXE) in occupational health, nutrition, and environmental studies, including analyses of solid wastes and aerosols. The IAEA supports such programs not only by providing funding, but also through quality assurance and information services.
