Radiate light (9)

Ross

I believe the answer is:

fluoresce

'radiate light' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for fluoresce that I've seen before include "glow brightly" , "Emit light when irradiated" .)

I've seen this clue in the Sydney Morning Herald.
