I came across the news of NASA-funded fusion rocket project which reminds me of my fusion rockets, so I decided to ask about the radiation shields (radshield). Do radiation shields reflect or absorb neutrons?

Note: Terminology
Reflect: The radshield 'reflects' neutrons, sending them back into space without making the radshield hotter.
Absorb: The radshield 'absorbs' neutrons, turning them into heat that heats the radshield up.

It'd depend on what the radiation shield is made of. I'm still wanting to see a Lithium radiation shield decompose into Tritium.
