Im talking about more than Gamma Rays. Rulk absorbs practically everything I think the Hulk should to he can absorb it also and im fairly sure he could do it to Kryptonite. Would you like to see Hulk absorb more why or why not ?

While it is true that Hulk does absorb gamma radiation/energy, there's no real proof that he can't absorb other forms of radiation/energy. In fact, he's shown to absorb cosmic radiation/energy, mystical energy (dark & light) on a couple of occasions.

I'm sure he does but, it isn't a conscious ability. Also red hulk does really absorb anymore.

He does when he can.
