Absolute activation analysis

{
  "id": "MLC-T-CHM-000046",
  "term": "Absolute activation analysis",
  "field": "Chemistry",
  "definition": "A method of activation analysis where the mass of an analyte is determined directly from the measured activity without the use of a chemical standard. This calculation requires precise knowledge of all relevant physical parameters, including the neutron flux, irradiation and decay times, nuclear cross-sections, and detector efficiency. The technique contrasts with comparative activation analysis, which relies on irradiating a standard of known composition alongside the unknown sample.",
