Zudgemud posted:If the plutonium pellets come close enough to each other they go critical. They are shaped like rods to prevent enough mass to be close enough to each other to cause a runaway chain reaction. If they had a more compact shape such as a sphere they would go critical. The pellets can easily roll and touch touch each other due to bad (even worse) handling and thereby cause a criticality event that will likely kill people. Boy let me tell you about how the first nuclear weapons were designed! They were in fact, a gun where you had two sub-critical masses of Uranium and you fired one into the other and squeezing them together in the right shape made them supercritical and then BOOM! In all seriousness though, if you want a fantastically explained intro to Nuclear Weapons and how it all works, SA's own resident illectro a.k.a. Scott Manley's "Going Nuclear" series is amazing. Here's the first video: https://www.youtube.com/watch?v=pWWjbnAVFKA

Zudgemud posted:Edit: I never thought about it before but you could make a plutonium musket ball or possibly rifle round that would cause a criticality event when it hits the target. DelphiAegis beat me to it, but this was almost literally how the bomb dropped on Hiroshima in WW2 worked (a "gun type" weapon). It used Uranium-235, not plutonium, though.  Nagasaki was a different beast - that was an "implosion" type - basically what all nuclear weapons have used since - where a single, subcritical mass of plutonium, is compressed all at once into a critical mass by being surrounded by very carefully shaped high explosive "lenses", which, when exploded, compress the plutonium close enough that it goes boom.  Read Command and Control by Eric Schlosser if you want to know quite how much duct tape and baling wire used to be used in nuclear weapons. Some of the safety wtfs are incredible.

Monkey Fracas posted:lmao the little anti-roll safety nubs They would certainly help. The problem is that the anti-roll nubs are on the steel storage tubes (top row). When the plutonium rods (bottom row) are outside the storage tubes then the engineered safety margins are no longer in place and an accidental criticality excursion becomes very possible.

Oh gently caress, they just wanted to show how nice they looked. Repeated safety lapses hobble LANL’s work on U.S. nuclear warhead cores article posted:It then set in motion a calamity of a different sort: Virtually all of the Los Alamos engineers tasked with keeping workers safe from criticality incidents decided to quit, having become frustrated by the sloppy work demonstrated by the 2011 event and what they considered the lab management’s callousness about nuclear risks and its desire to put its own profits above safety.

I think my favorite is still that for Trinity, they for some reason had someone stay with the bomb at the top of the tower to "guard" it overnight before the test and the dude who designed the mechanism that made sure all the explosive "lenses" detonated right got the short straw. A thunderstorm rolled in that night, so he was up in a little shack at the top of a tower in the middle of nothing with a bomb of a type that had never been detonated before, and he also new enough about the trigger mechanism to know that a lighting strike could set it off.

I guess you could structure the bullet in a way that it's rigid when being pushed from behind, but collapses when the tip hits something firmer than air.

The Lone Badger posted:"I mean you'll still die, but it'll make it easier to recover your body." If you pick it up and hold it at arms length, and your arms are 1 meter long, you have 6 minutes 56 seconds to "DROP & RUN" before you leave the "probably survive" window of radiation exposure and enter the "50% chance you die painfully" window. If you hold it up to your chest to squint at it and read it, it's like 15 seconds or some poo poo. That's a helluva fuckin source.

If you collapsed and died on top of that source, what would your body be like? I assume it wouldn't be able to decay by normal processes, would it just slowly desiccate and mummify?

TotalLossBrain posted:I believe the primary concern is that Pu is a good alpha emitter, which means it spews heavy particles at (relatively) low speeds, which wreck the poo poo out of the insides of people when ingested. Yeah, radiation protective suits don’t really shield you from radiation, so much as they prevent inhalation and ingestion of particles, and stop particles sticking in your hair etc. I mean they shield you from alpha and beta particles, but normal clothes pretty much do that. Also effective against UV radiation!

When they say "exceeding rare and expensive" they are under selling it. It would cost $189 million just for the 7 grams of californium to use for the bullet.

Yeah, it'd cost about a billion dollars just for the raw material, and somehow 800 million of that would end up in LockMart's hands.
