# How do Fusion/Fission Gamma Rays Compare?

## Main Question or Discussion Point

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".
