Now the radiation dose that the LHC beam could give you could kill you 76,000 times over, but the radiation dose you'd receive from a beam of say 200… - Suzie Sheehy

What I'm going to do is suck out all of the air out of this container and see what happens to marshmallow man, or indeed, what might happen to our pet bunny rabbit in a particle accelerator. ...Oh my gosh it's huge! That's amazing! Sorry, we haven't tested this. I didn't realize it was going to be this good. ...That's probably what would happen to your little bunny rabbit, but in a slightly more horrific fashion.

So you can actually put your head in the beam of an accelerator and survive it. And he's not the only one to have done it.

[I]f you take Einstein's equation E=mc², E is energy, m is the mass and c is 299,792,458 meters per second, so that squared, I'd have to get to tell me what that is, but that's a very big number. So it takes an enormous amount of energy to create even a tiny tiny amount of matter. So that's why, over the years, our machines have gotten bigger and bigger and bigger, and reached up to higher and higher energies in order to create particles of higher and higher masses. Now that might seem slightly counterintuitive, but if we look down at the low energy scale, we get our... everyday objects, and in fact up here at sort of 10 MeV, which is like a sort of everyday energy scale, are the up and s where our s and s are created from. And if we go up in energy scale, we slowly... over time discovered all these other types of s and s, and all these other things that seem to play no role in our everyday lives.
