Activity growth curve

  "id": "MLC-T-CHM-000199",
  "term": "Activity growth curve",
  "field": "Chemistry",
  "definition": "A plot of the activity of a radionuclide against time during a period when that activity is rising, either because a precursor nuclide is decaying into it or because it is being produced by activation in an irradiation. For a parent-daughter pair the shape depends on the two half-lives and approaches transient or secular equilibrium, whereas under irradiation the activity climbs toward a saturation value.",
