  "term": "Prompt gamma radiation",
  "field": "Chemistry",
  "definition": "Gamma rays emitted almost instantaneously, within approximately 10^-12 seconds, following a nuclear reaction or radioactive decay. These photons arise from the de-excitation of excited nuclear states formed during the initial event. Prompt gamma radiation is distinct from delayed gamma radiation, which is emitted later from longer-lived excited states.",
