  "term": "Biological half life",
  "field": "Chemistry",
  "definition": "The time required for half of a substance, such as a drug or radionuclide, to be eliminated from a biological system through metabolic or excretory processes. This value is distinct from the physical half-life, which describes the decay rate of a radioactive isotope. It is a key parameter in pharmacokinetics and radiation dosimetry.",
