Keyword Definition

Instrumental neutron activation analysis (INAA) can be categorised according to whether gamma rays are measured during neutron irradiation (prompt gamma-ray neutron activation analysis, PGNAA) or at some time after the end of the irradiation (delayed gamma-ray neutron activation analysis, DGNAA).  DGNAA is more common.

Several Canadian geochemical laboratories provide DGNAA services.  Irradiation is carried out at several different facilities, including

  • Slowpoke reactor at McMaster University, Hamilton, Ontario
  • Triga reactor at Washington State University, Pullman, Washington, USA
  • TRIUMF cyclotron at  the University of British Columbia, Vancouver
