5. Anatoli Bugorski
As a researcher Bugorski took his job with particle accelerators and proton beams very seriously. So, in 1978 when a machine was malfunctioning Bugorski took it upon himself to see what the problem was. Once he stuck his head in the machine though his brain was subjected to 600 rads (500 is enough to kill someone) Over the next few days his entire face swelled up before it starting peeling off, somehow though his brain was never negatively impact by the blast. Decades on Bugorski isn’t able to move the left side of his face and the accident has actually meant he has never gotten any wrinkles! Better than botox I guess!
