A lot of s' food is irradiated before they send it up so that they... aren't going to get sick from it. - Suzie Sheehy

Four different types of particles: electrons, s, s and gold atoms. ...Can anyone suggest which one you can't put in a particle accelerator? ...A . Yep! Do you know why? Because it isn't charged. Thank you very much. ...[I]t doesn't have an .

So my number two thing you probably shouldn't do with a particle accelerator. You probably shouldn't put your head in the beam... On this one I want to have... a vote... What might kill you first? ...Would your head freeze because of the ? It's at minus 271 degrees <nowiki>[</nowiki>Celsius] in some accelerators... take the Large Hadron Collider for example. There the magnets are pretty cold, or would the heat from the beam make your head explode, or would your head explode from the , or would you die from the dose? ...I want a show of hands for which one you think would get you first.

So what about the heat from the beam? Well this is a challenge... [I]t's actually incredibly difficult to stop the beam, and if you put your head in front of the beam... it would actually go straight through and out the other side. In fact it has enough energy to go through your head and out the other side about 100,000 times before it loses all it's energy... [T]hat's actually one of the issues they had to deal with when designing the machine, is how do you stop the beam... [W]e want to stop it occasionally, intentionally...
