The 11 pages that link to Radiometry, each with the reason it gives.

• PolarimetryCompared with: Radiometry measures energy flow, while polarimetry resolves polarization state.

• IlluminanceCompared with: Its radiant quantities differ from illuminance's vision-weighted photometric quantities.

• Luminous efficacyCompared with: Radiometry counts energy directly; luminous efficacy relates that power to visually weighted output.
