A man exposed to a large amount of radiation with an accelerator

There seems to be a case in the past when a man stabbed his head into the accelerator in Russia was exposed to strong radiation on her face.

It is described how men who have been exposed to strong radiation are getting out, their contents are very shocking, I can make you realize how terrible radiation is.

Details are from the following.
Neatorama Blog Archive The Man Who Stuck His Head Inside a Particle Accelerator

Researcher Anatoli Bugorski (36 years old), who worked at the High Energy Physics Laboratory, said he was checking for accelerators not working properly. So I found a device that is leaning slightly, so I tried to fix the head thrusting device and it took a very dazzling light. Where Mr. Bugorski thrusts his face, where radiation beams pass, Mr. Bugorski seems to have been exposed to radiation of about 500 to 600 rad (dead enough) radiation.

Mr. Bugorski seems to have not felt pain, but when the left side of the face is Mr. Bugorski, it swells to the extent that it is unknown and it is transported to the hospital. He said that radiation continued to burn the skin of the head, cranial bones and brain cells for several days thereafter. After that the nerves continued to be burned, the nerve on the left side completely disappeared in about 2 years, it seems that part of the face got caught.

Mr. Bugorski seemed to have had seizures several times during the past few years. Because the nerve on the left side of the face had died, even when concentrating on something, it seems that there was no change in expression on the right side of the face.
