  "term": "Radiant intensity",
  "field": "Chemistry",
  "definition": "The radiant power emitted by a point source per unit solid angle in a specific direction. It describes the directional distribution of radiation from a source, unlike radiant power which is the total power emitted in all directions. Radiant intensity is symbolized by I or Iₑ and is measured in SI units of watts per steradian (W sr⁻¹).",
