You have to admit that the setup of this experiment makes riding a motorcycle, without a helmet, with a .1% BAC, look like more responsible behavior.
The other people in the room got a couple years’ worth of rads from his mistake didn’t they?
I’m sure they rationalized not using an apparatus for this due to embrittlement, thermal expansion, response time, or all three. But from the perspective of someone looking back on this era 50 years later (now 80), Jesus fucking Christ.
Carpenter’s pencils as spacers would have saved his life.
In fact Wikipedia says he was a dumbass:
> The standard protocol was to use shims between the halves, as allowing them to close completely could result in the instantaneous formation of a critical mass and a lethal power excursion.
> By Slotin's own unapproved protocol, the shims were not used. The top half of the reflector was resting directly on the bottom half at one point, while 180 degrees from this point a gap was maintained by the blade of a flat-tipped screwdriver in Slotin's hand. The size of the gap between the reflectors was changed by twisting the screwdriver. Slotin, who was given to bravado,[11] became the local expert, performing the test on almost a dozen occasions,
Transposed to a very different time and place, the "bravado" here really reminded me of the "repeated dives in a carbon-fiber sub to crushing depths" -- with such setups, it's just a matter of when, not if.
Those people died before they knew they were fucked. At some point acute radiation exposure makes it so they can’t even dose you with morphine properly. Same thing happened at Chernobyl if I recall.
That's something that seems to be missing from how people perceive the threat of nuclear weapons. It's pleasant and convenient to believe you'll instantaneously combust in a fireball as hot as the sun, but actually only very few people will be so lucky. Mostly it'll take days, weeks, months, and years. Not seconds or fractions of seconds.
This is Soviet propaganda. The real number from Nagasaki and Hiroshima was about half of the casualties were instant. Furthermore fallout is much more understood: after a few short days of hiding inside, the radiation levels will have fallen to where normal life can largely resume without fear, reducing the number of slow casualties.
Same with accidents involving nuclear power generators (and their waste). Most people on HN won't have the chance to engage in Slotin's flavor of bravado... But the kind involved in recklessly, breathlessly advocating for nuclear power? Quite common, here.
The real demon here isn't the core it's the flathead screwdriver--lowest among tools. The number of times I've slipped dealing with flathead screws, or stripped them, or nearly had an aneurysm from them is uncountable. No wonder one of these cursed devices played a central role here as well. But yeah he totally could have chucked a couple sticks in there to keep the halves separate and then he wouldn't have died. Oops.
