Some scientists were talking about the Super Earth and its Red Dwarf star saying that although the star is colder than ours and the planet is closer then it could be in the habitable zone, however wouldnt red dwarf emit some sort of crazy strong gamma radiation compared to our sun as its nuclear fusion would be jigglying all crazy. you get the idea.

Your thinking of the blue star end of the spectrum, but your on the right track just asking the wrong question. The real question is weather of not the planet has a strong enough magnetic field to shield itself from the sun's radiation. If is wasn't for our magnetic field life would have never risen of earth.
Mars is a prime example what happens when your planets core solidifies and it looses is magnetic field. The atmosphere on mars, and probably most of it's water was and is being blown away by the solar wind. And the surface is mars is so radioactive that it's self sterilizing.
It's only the magnetic field created by the convection of earth's outer liquid core that shields us from such a fate.

Red dwarf stars have far longer lives than our Sun. Not only do they produce less heat, and emit less radiation, they are very stable. A few Red dwarf stars have been known to emit dangerous flares, but this is uncommon. Therefore, a planet in orbit around a red dwarf would be relatively safe from radiation at least in comparison to our Sun. It's not likely however, that a planet devoid of a magnetic field, could be completely invulnerable to even a weak solar wind from a smaller star.

Red dwarf stars emit most of their energy in infrared light, lower energy than the visible light yellow stars emit. Even high-mass, hot, blue stars are too cool to radiate much X-ray or gamma ray radiation.

I would think that with a red dwarf sun that gamma radiation would not be a huge concern because the enormous amount of energy needed to for gamma rays to be produce

Red dwarfs are stable stars just not as big or as hot as the sun. Generally, the hotter the star the more unstable they are. Those in the yellow and red range are the most stable and last a looooong time.

Maybe. But I think it is the hot blue stars that are known to do that. Red dwarf stars are pretty tame as far as I know.
