How do Fusion/Fission Gamma Rays Compare?

[KangOfCanada]

My concerns are all about how much shielding would be needed for a nuclear reactor. Would aneutronic He3-He3 fusion produce less energetic photons than fission to be more easily used in more mobile reactors? Obviously very few neutrons are made in this reaction so that leaves the high energy photons the remaining concern.

More of a sci-fi interest, the power armour in the fallout 4 have almost no shielding for the "fusion cores".

I do not have information about He3+He3 that produces gammas or neutrons, only X rays (very easy to shield). (perhaps it emits but there is no information)

Very good reaction, but where is the He3? It is impossible to buy, you should use another reaction to generate it
