InitialDave posted:How can you be criminally negligent for someone stealing dangerous material if you're prevented from removing it, even having explained that it's dangerous? This rationale is fairly common in the legal system; "the actions of this court preventing you from doing otherwise notwithstanding; you are hereby found to be criminally negligent..." Basically by admitting any fault the court (and thereby the state) would assume liability for the outcome of the spread of radioactive materials. It was easier/cheaper to just hang the clinic's owners out to dry. OTOH it is curious how you'd forget something containing high levels of radioisotope when moving.

Geirskogul posted:And you've posted one of my two biggest "whoa...drat. Life sucks sometimes" wikipedia articles. Here's the other one, which could be described as a mechanical failure: I was told a story that at TWA a mechanic was performing a combustion chamber Inspection on a JT8D engine that used a small radioactive isotope and X-ray film. Somehow small isotope was left out and later discovered by another mechanic placed it in his back pocket thinking it looked cool and not knowing what it was. Word is he had to have his leg amputated after the radiation damaged it.

They are usually Cobalt-60 and put out ungodly amounts of gamma radiation. Normally housed in a shielded carrier that gets opened via a cable just for the exposure. Sometimes it gets left open, sometimes it falls out, gets picked up by others, etc.

The end of the rail shows a break, not a natural end. It froze, shrank, broke under tension.

That's about like putting a giant gap (say, 12-18" long) straight across a bridge as an expansion joint. e: friend of mine blew up the gears in his dana 30 front differential. Was about to start setting up the new ring and pinion and noticed this...

If you want to clear an elevator of hardass union boilermakers just walk in carrying an xray source. Those radioactive stickers scare the hell out of people for some reason. I always got a wide berth when i was transporting that thing around a work site.

Absolutely the same level I see now that I'm in the nuclear industry.

To be fair, when this happened the research was: a) still in its infancy, and b) rushed because of Manhattan project and all that. Additionally, that research took place at LANL (Los Alamos) - notorious for its young and careless scientists that ran aground with the military rules there even into the 90's (remember the misplaced hard-drives?) After the late 1940's, such accidents were pretty much eliminated in the US. There was one more fatal criticality accident after that. And it was just an unfortunate dude looking through an inspection window in a mixing vessel right after the stirrer had been turned on. The solution in the vessel was a bit heavier in Pu (maybe Ur) than expected. Bang, blue flash, dude gets cooked by 'approximately' 13,000 REM. Ouch.

Yeah, they were pretty much rockstars of the time. They were all young scientists that got to be on the cutting edge of a new field that was highly sought after by the military. They played it fast and loose and as long as the military got results, they didn't care.

If you haven't heard about demon core, check out the movie "Fat Man and Little Boy" about the development of the bomb in Los Alamos. Sure, it's got John Cusack in it, but it's okay, his character dies of radiation poisoning from the demon core incident. -Not a spoiler, you know the incident happens by reading this thread.-

Well okay....I suppose SL-1 was a criticality "accident". There were rumors from people who knew those involved that said it was a love triangle gone wrong and the removal of the control rods was in fact not accidental. Hard to say now. At this point, let me introduce you to Harold McCluskey! Radio-chemical operator at the Hanford Plutonium Finishing Plant (PFP). During a glove-box operation gone wrong, the box exploded in his face and embedded lots of Americium-241 particles in his skin. He was at once the most radioactive man alive. Thanks to some innovative new treatments (chelation), he lived for over another decade and eventually succumbed to old age. People were scared of him, his church group was skittish, and boy oh boy was the city of Richland pissed about their brand-spanking-new ambulance requiring burial after transporting poor Harold. I suspect that Fallout's Harold was based on him. http://en.wikipedia.org/wiki/Harold_McCluskey PS: I live in Richland and have worked out there.

Likely Alang or similar place. http://en.wikipedia.org/wiki/Alang The conditions are horrible and ships are dismantled with no consideration for the workers or the environment. If you get a chance to watch the documentary on it, watch it. I imagine that if you'd interviewed american factory workers circa 1850 you'd hear a lot of the same answers.

These have been put out in favor of linear accelerators in the medical field, only a few labs still carry cobalt 40 systems for non-medical purposes. I thankfully normally deal with sub 150Kv medical imaging systems, but we do have a 1.5Mkv linear accelerator that you can gain access to via a 2 foot thick steel/lead lined vault door.

There were rumors from people who knew those involved that said it was a love triangle gone wrong and the removal of the control rods was in fact not accidental. Hard to say now. The love triangle story is so ridiculous that it should have been rightfully forgotten by now. Also, SL-1 final rod maneuver would be termed a reactivity initiated accident (RIA). Hypothetical RIAs, like the ejection of one or more control rods from the core, are the kind of hypothetical event that people design all reactors (and their safety margins) around. SL-1 was no exception, but the behavior of the core changed as the affixed neutron poison inserts (which serve as a kind of permanent brake on the rate of reaction) came loose from the core. It should not have been possible to begin with. It was negligence that allowed it to get that far.

I'm actually sort of surprised it was the front wheels rather than the rear ones. You'd think the ones that have to deal with the engine force and also extreme (relative to the front) slip angles would go first, although I guess there's more weight in the front.

I wouldn't be surprised if it happened on turn-in, as the front wheels have to push the car to make it rotate too.

As a typeface-affluent person I had a lot of shame going on there. I'm just used to seeing Impact used in that context that I totally overlooked it.
