Apropos of nothing else that was going on in the Tavern today, a chap started to give me the heads-up on a fellow who worked with dangerous kit and made a bit of a name for himself.
I was reminded of one Phineas Gage, but the chap in question is not of Gage's era but of today, and far from working on anything as pedestrian as a railway, he was working with much more powerful gizmos.
It was in Russia and the kit was the U-70 particle accelerator. A question that very few ask...What happens when you stick your head into a particle accelerator?
But hey, let me pull you a pint as Joel Frolich tell it himself. He is going to baffle you with science. Well, some of you.
This is what happened to the scientist who stuck his head inside a particle acceleratorWhat would happen if you stuck your body inside a particle accelerator? The scenario seems like the start of a bad Marvel comic, but it happens to shed light on our intuitions about radiation, the vulnerability of the human body, and the very nature of matter.
Particle accelerators allow physicists to study subatomic particles by speeding them up in powerful magnetic fields and then tracing the interactions that result from collisions. By delving into the mysteries of the universe, colliders have entered the zeitgeist and tapped the wonders and fears of our age.
As far back as 2008, the Large Hadron Collider (LHC), operated by the European Organization for Nuclear Research (CERN), was charged with creating microscopic black holes that would allow physicists to detect extra dimensions. To many, this sounds like the plot of a disastrous science-fiction movie. It came as no surprise when two people filed a lawsuit to stop the LHC from operating, lest it produce a black hole powerful enough to destroy the world.
But physicists argued that the idea was absurd and the lawsuit was rejected.Then, in 2012, the LHC detected the long-sought Higgs boson, a particle needed to explain how particles acquire mass. With that major accomplishment, the LHC entered popular culture; it was featured on the album cover of Super Collider (2013) by the heavy metal band Megadeth, and was a plot point in the US television series The Flash(2014-).
Come along young Joel. This isn't a long, drawn out joke. Get it out, sir.Yet, despite its accomplishments and glamour, the world of particle physics is so abstract that few understand its implications, meaning or use. Unlike a NASA probe sent to Mars, CERN’s research doesn’t produce stunning, tangible images. Instead, the study of particle physics is best described by chalkboard equations and squiggly lines called Feynman diagrams. Aage Bohr, the Nobel laureate whose father Niels invented the Bohr model of the atom, and his colleague Ole Ulfbeck have even gone as far as to deny the physical existence of subatomic particles as anything more than mathematical models.
Which returns us to our original question: What happens when a beam of subatomic particles traveling at nearly the speed of light meets the flesh of the human body?
Perhaps because the realms of particle physics and biology are conceptually so far removed, it’s not only laypeople who lack the intuition to answer this question, but also some professional physicists.
Hmmmmm. Has the tenor of 'famous last words', eh? Hahaha. But if you get a few free moments you could do a lot worse than watching the fine and funny Professor and his equally sound mates at Notts Uni, on YT. They have so many sciencey things to ponder along with you. Look up 'Sixty Symbols'. I can assure you that entertainment is a business that has missed some real performers.In a 2010 YouTube interview with members of the physics and astronomy faculty at the University of Nottingham, several academic experts admitted that they had little idea what would happen if one were to stick a hand inside the proton beam at the LHC. Professor Michael Merrifield put it succinctly: “That’s a good question. I don’t know is the answer. Probably be very bad for you.” Professor Laurence Eaves was also cautious about drawing conclusions. “[B]y the scales of energy we notice, it wouldn’t be that noticeable,” he said, likely with a bit of British understatement. “Would I put my hand in the beam? I’m not sure about that.”
Such thought experiments can be useful tools for exploring situations that can’t be studied in the laboratory. Occasionally, however, unfortunate accidents yield case studies: opportunities for researchers to study scenarios that can’t be experimentally induced for ethical reasons. Case studies have a sample size of one and no control group. But, as the neuroscientist V. S. Ramachandran has pointed out in Phantoms in the Brain (1998),
it takes only one talking pig to prove that pigs can talk.
See, I told you. But you all know of P.Gage, don't you?On Sept. 13, 1848, for example, an iron rod pierced through the head of the US railway worker Phineas Gage and profoundly changed his personality, offering early evidence of a biological basis for personality.
And on July 13, 1978, a Soviet scientist named Anatoli Bugorski stuck his head in a particle accelerator.
On that fateful day, Bugorski was checking malfunctioning equipment on the U-70 synchrotron—the largest particle accelerator in the Soviet Union—when a safety mechanism failed and a beam of protons traveling at nearly the speed of light passed straight through his head, Phineas Gage-style.
It’s possible that, at that point in history, no other human being had ever experienced a focused beam of radiation at such high energy.
As you can see, Anotoli was not at all happy about it.Although proton therapy—a cancer treatment that uses proton beams to destroy tumors—was pioneered before Bugorski’s accident, the energy of these beams is generally not above 250 million electron volts (a unit of energy used for small particles). Bugorski might have experienced the full wrath of a beam with more than 300 times this much energy, 76 billionelectron volts.
Proton radiation is a rare beast indeed. Protons from the solar wind and cosmic rays are stopped by Earth’s atmosphere, and proton radiation is so rare in radioactive decay that it was not observed until 1970. More familiar threats, such as ultraviolet photons and alpha particles, do not penetrate the body past skin unless a radioactive source is ingested. Russian dissident Alexander Litvinenko, for instance, was killed by alpha particles that do not so much as penetrate paper when he unknowingly ingested radioactive polonium-210 delivered by an assassin. But when Apollo astronauts protected by spacesuits were exposed to cosmic rays containing protons and even more exotic forms of radiation, they reported flashes of visual light, a harbinger of what would welcome Bugorski on the fateful day of his accident.
According to an interview in Wired magazine in 1997, Bugorski immediately saw an intense flash of light but felt no pain. The young scientist was taken to a clinic in Moscow with half his face swollen, and doctors expected the worst.Ionizing radiation particles such as protons wreak havoc on the body by breaking chemical bonds in DNA. This assault on a cell’s genetic programming can kill the cell, stop it from dividing, or induce a cancerous mutation.
Cells that divide quickly, such as stem cells in bone marrow, suffer the most. Because blood cells are produced in bone marrow, for instance, many cases of radiation poisoning result in infection and anemia from losses of white blood cells and red blood cells, respectively. But unique to Bugorski’s case, radiation was concentrated along a narrow beam through the head, rather than being broadly distributed from nuclear fallout, as was the case for many victims of the Chernobyl disaster or the bombing of Hiroshima.
For Bugorski, particularly vulnerable tissues, such as bone marrow and the gastrointestinal track, might have been largely spared. But where the beam shot through Bugorski’s head, it deposited an obscene amount of radiation energy, hundreds of times greater than a lethal dose by some estimates.
|He still does NOT look a happy chappy.|
So many questions a chap might ask.And yet, Bugorski is still alive today. Half his face is paralyzed, giving one hemisphere of his head a strangely young appearance. He is reported to be deaf in one ear. He suffered at least six generalized tonic-clonic seizures. Commonly known as grand mal seizures, these are the seizures most frequently depicted in film and television, involving convulsions and loss of consciousness. Bugorski’s epilepsy is likely a result of brain tissue-scarring left by the proton beam. It has also left him with petit mal or absence seizures, far less dramatic staring spells during which consciousness is briefly interrupted. There are no reports that Bugorski has ever been diagnosed with cancer, though that is often a long-term consequence of radiation exposure.Despite having nothing less than a particle accelerator beam pass through his brain, Bugorski’s intellect remained intact, and he successfully completed his doctorate after the accident. Bugorski survived his accident. And as frightening and awesome as the inside of a particle accelerator might be, humanity has thus far survived the nuclear age.
Safety protocols, anyone.
Does the Large Haldron Collider at CERN have 'Safe-Spaces' for newly minted Graduates just out of Uni?
Does an invisible particle beam of minute proportion constitute a micro-aggression?
Things to ponder over a pint, I think.
I shall pull a few for you and Joel.
So, what did happen?ReplyDelete
Er..... what Joel said happened.Delete
My partner and I stumbled over here by a different website and thought I should checkReplyDelete
things out. I like what I see so i am just following you.
Look forward to looking at your web page again.
