Absolutely, mostly as 15 MeV neutrons. This causes neutron activated secondary radioactivity in surrounding material. On decommissioning a fusion reactor (assuming we ever figure out how to build one) this part of the reactor would have to be handled as radioactive waste, just as the non-fuel assemblies of a fission reactor must be treated now. There is also alpha radiation, but the biggest problem here is weakening and flaking of a thin layer of reactor vessel wall due to helium bubble accumulation.

absolutely , the multiple chain reactions produced sub atomically during a nuclear reaction are uncontrollable and happen faster than the speed of light .many adverse bi-products are produced mostly which are harmful including u.v radiation when light is created by light

High energy radiation that travels faster than the speed of light in the medium it is traveling through produces Cherenkov Radiation, a blue glow. However without shielding (water, leaded concrete, offset viewing mirrors, etc.) to prevent the original radiation from reaching you, you will be dead in a couple weeks from Radiation Poisoning. The Cherenkov Radiation had nothing to do with this, it just warns you.

The sun is powered by nuclear fusion, and the resulting hot material in the sun and specifically on its surface radiates visible light along with other frequencies.

No - endothermic reactions absorb energy, so they absorb light, not produce it.
