Anatoli Petrovich Bugorski (Russian: Анатолий Петрович Бугорский; born 25 June 1942) is a Russian retired particle physicist. He is known for surviving a radiation accident in 1978, when a high-energy proton beam from a particle accelerator passed through his head. [1] [2]
The cooling system was restored before the meltdown but the unit had to be shut down due to the elevated cost of the repair. 0: 220 [39] 3 March 1992: Sosnovy Bor, Leningrad Oblast, Russia: An accident at the Sosnovy Bor nuclear plant leaked radioactive iodine into the air through a ruptured fuel channel. February 20, 1996
A particle beam is a stream of charged or neutral particles.In particle accelerators, these particles can move with a velocity close to the speed of light.There is a difference between the creation and control of charged particle beams and neutral particle beams, as only the first type can be manipulated to a sufficient extent by devices based on electromagnetism.
Nuclear spallation is one of the processes by which a particle accelerator may be used to produce a beam of neutrons. A particle beam consisting of protons at around 1 GeV is shot into a target consisting of mercury, tantalum, lead [1] or another heavy metal. The target nuclei are excited and upon deexcitation, 20 to 30 neutrons are expelled ...
Particle therapy is a form of external beam radiotherapy using beams of energetic neutrons, protons, or other heavier positive ions for cancer treatment. The most common type of particle therapy as of August 2021 is proton therapy .
The Therac-25 is a computer-controlled radiation therapy machine produced by Atomic Energy of Canada Limited (AECL) in 1982 after the Therac-6 and Therac-20 units (the earlier units had been produced in partnership with Compagnie générale de radiologie (CGR) of France).
Research in this area has focused on the three most common sources of radiation used for these applications, including gamma, electron beam, and x-ray radiation. [ 17 ] The mechanisms of radiation damage are different for polymers and metals, since dislocations and grain boundaries do not have real significance in a polymer.
The second phase of the treatment was abandoned on medical advice, and Norris survived for some time after the overdose. January 23, 2008 – A licensed radiology technologist, Raven Knickerbocker, at Mad River Community Hospital in Arcata , California performed 151 CT scan slices on a single 3 mm level on the head of a 23-month-old child over ...
