  "term": "Branching fraction",
  "field": "Chemistry",
  "definition": "The probability that a radionuclide will undergo a specific decay pathway when multiple decay modes are energetically possible. It is expressed as a dimensionless ratio, representing the number of nuclei decaying via a particular mode divided by the total number of nuclei decaying. The sum of all branching fractions for a given radionuclide must equal one.",
