While working on a particle accelerator, AnatoliAPR 30 2007

While working on a particle accelerator, Anatoli Bugorski accidentally put his head into the proton stream. "The left half of Bugorski's face swelled up beyond recognition, and over the next several days started peeling off, showing the path that the proton beam (moving near the speed of light) had burned through parts of his face, his bone, and the brain tissue underneath." Some photos here. (via cyn-c)
