What Would Happen If You Peed Into a Particle Accelerator?

I have visited CERN and they have sections of the accelerator you can look at. It's a mess--to you and me--wires and tubes. This has not been built for consumers. There's no pink model; there will not be a thinner and lighter 2.0; and Nike is not sponsoring a limited edition line. In other words--no safety measures in place for rogue urinators.
