Neutron Activation Analysis

Neutron Activation Analysis (NAA) is a non-destructive technique for specialized analysis of liquid and solid samples. Analysis is conducted using a nuclear reactor, SLOWPOKE-2, housed at SRC Environmental Analytical Laboratories.

NAA involves analyzing uranium in certain sample matrices and organic halides analysis. Alternate techniques are available for these tests, but SLOWPOKE-2 has the advantages of being a non-destructive technique and requiring little sample preparation.

Options available for parameters and sample matrices:


  • Groundwater and surface water
    • Inductively coupled plasma-mass spectrometry (ICP-MS)
  • Mining liquids 
    • ICP-MS or SLOWPOKE-2
  • Soil, sediments, biological tissue, vegetation
    • ICP-MS
  • Mining exploration samples
    • ICP-MS
    • SLOWPOKE-2
    • Titrimetric (>5% U3O8)
