To most people 'radioactive' means 'invisibly lethal', which isn't a good starting place (in actual fact everything and everyone is radioactive, to varying extents). This means the OP asked the wrong question (and should instead be asking "Is using fusion power safer than not using fusion power?". And it so happens that the answer is "probably" since the realistic alternatives have been shown more dangerous for complicatedly practical reasons).To me, the term 'radioactive' indicates a decay process. That might not be a proper definition. Of course, fusion releases EM radiation. So do light bulbs and radio stations, but I don't consider them radioactive. I was aware of fusion releasing protons, but not neutrons. Beta decay is just the release of electrons, which again is not something that I think of as being hazardous radiation. After all, that's what makes a TV work.
