What types of electromagnetic radiation that reaches earths surface

The electromagnetic emissions from solar flares aren't much different from those produced by the rest of the sun, but do include somewhat higher levels of soft x-rays and low-energy gamma rays. These emissions are of course dwarfed by the normal output of the sun, and are of such low density by the time they reach Earth that they have no discernible effect on organic matter.
