The chlorophyll absorbs the energetic UV radiation, too energetic too feed into the electron pathways actually used to create glucose, and the excited chlorophyll emits light in a lower energy band, typically within the visible spectrum.
If you are asking about literall gamma-radiation, then in principle it is possible via the same mechanism but in reality no, it will be insignificant.
