  "id": "MLC-T-CHM-004511",
  "term": "Fluence rate",
  "field": "Chemistry",
  "definition": "The radiant power incident on a small sphere divided by the cross-sectional area of that sphere, expressed in units of W m⁻². It represents the rate at which radiant energy passes through a given area, considering all directions of incidence. This quantity is particularly relevant in photochemistry for describing the intensity of light exposure.",
