I’ve heard people say there is no fallout, but there typically is a fission bomb in the secondary stage. Where does its radiation go? Is it just blown away by the fusion bomb so it’s no longer as deadly? Isn’t it still there though? Is it just weaker?

I will break this down in two parts. First the trigger (primary) and second the hydrogen bomb (secomdary) part.
The “spark” primary to the hydrogen bomb is an atomic bomb it consists of either enriched uranium or plutonium (or a mix) and splits atoms giving off energy. You need this oo generate tremendous heat and pressure.
The “plug” secondary is the cylindrical part, it consists of a radiation case, some foam or plastic and a some hydrogen. There also is uranium to first be energized by x rays then emit neutrons. The neutron combines with the hydrogen and helium is formed. So a pure fusion weapon does not have plutonium and only creates helium… but it doesn’t exist because the secondary needs the pressure and heat of the sun to fuse elements. As it fuses and becomes helium it gives off tremendous energy.
