What are we going to do about
Cosmic Rays from Black Holes?

We do get radiation from *near* black holes, where matter is being plasmized by the intense tidal forces near the event horizon. The radiation is very harmful: x-rays and gamma rays. Cosmic rays aren't really EM radiation and are streaming through us, sparsely, all the time.
Fortunately the closest black hole we have discovered is 1600 light years away. The ones which cause harmful radiation are always associated with another star. We have only found a handful. And they are far enough away as to be of no concern. Now if there was a black hole in close orbit around our sun, that would be a different story.

well black holes dont really radiate out much energy or particles. the very slowly do, and if you were close enough to the black holes event horizon they would cause you a problem. but when were 1600 lightyears away it wouldnt cause much problem. and why should we do anything about them. humans have been around for 2 million years, if they had an effect we would have noticed by now. thats societies problem. someone finds out about something and they assume its a problem, they pay no attention to the fact that its been going on for hundreds, thousands, maybe even millions of years.
and cosmic rays arent really electromagnetic radiation. they are just highly energetic particles, not necessarily photons. most are gamma rays, alpha particles, or electrons. since we have a magnetosphere. that protects us from charged particles only gamma rays and few alpha particles or electrons would get through since alpha particles have a +2 charge and electrons a -1 they would be effected by the magnetic poles. only gamma rays wouldnt.

Not exactly.
Nothing comes out of a Black Hole, except maybe
Hawking Radiation, (not proved).
Black Holes however can accelerate matter that
doesn't quite fall into them to relativistic velocities.
There is little we can do about cosmic, or for that matter, solar radiation, or supernova radiation,
or any kind of extra- terrestrial phenomina,
except duck.

definite, it relatively is a sub-field of astronomy. plenty is time-commemorated, and there are various particular observations. Very severe capability cosmic rays are intergalactic, and could be generated interior the super black holes interior the centers of galaxies, or consistent with possibility uncommon gamma-ray burst events. extremely severe capability cosmic rays are generated with the help of supernovae, and are partly restricted to the disk of the Galaxy with the help of the Galaxy's magnetic field.

I don't know much about the subject but I don't think that is possible. Black Holes have a very strong gravitational pull that would pull all the enrgy inside and since it would not release any energy it appears as a black hole.

Nothing, there are no rays of any kind coming from black holes.
