  "id": "MLC-T-CHM-007976",
  "term": "No carrier added",
  "field": "Chemistry",
  "definition": "A designation for a radionuclide preparation that is essentially free of any stable isotopes of the same element. This means that the specific activity, the radioactivity per unit mass of the element, is at or near its theoretical maximum. The term is distinct from 'carrier-free', which implies the complete absence of any stable isotopic atoms.",
