Ask Lemmy

Woah, good that he survived and it's impressive he continued to work in the field afterwards

As a researcher at the Institute for High Energy Physics in Protvino, Russian SSR, Anatoli Bugorski worked with the largest particle accelerator in the Soviet Union, the U-70 synchrotron. On 13 July 1978, Bugorski was checking a malfunctioning piece of equipment when the safety mechanisms failed. Bugorski was leaning over the equipment when he stuck his head in the path of the 76 GeV proton beam. Reportedly, he saw a flash "brighter than a thousand suns" but did not feel any pain. The beam passed through the back of his head, the occipital and temporal lobes of his brain, the left middle ear, and out through the left hand side of his nose. The exposed parts of his head received a local dose of 200,000 to 300,000 roentgens (2,000 to 3,000 Sieverts). Bugorski understood the severity of what had happened, but continued working on the malfunctioning equipment, and initially opted not to tell anyone what had happened.
