WA is like I dunno, Alaska. It's technically part of Australia but nobody from real Australia has ever been there or vice vercae, and really does it even exist? Who knows. New Zealand is closer.

High school chem teachers accidentally setting tables on fire, exploding pool balls made of nitrocellulose (not actually explosive it turns out, except for the manufacturing phase), people making underwear out of gun cotton to light on fire. Good times!

BattleMaster posted:FOOF thread makes me glad I only work with radioisotopes and nothing that's actually scary You should try working with scary radioisotopes! My ion chamber survey meter got saturated the other night (at least that's my best guess as to what happened) and for about 30 seconds I thought I had a ~0.8TBq source stuck outside of its shielding.

Industrial radiography. Looking for embedded conduits in a thick slab of concrete that night. On an even more osha note, a while back I was in Michigan testing some xray tubes as a possible replacement for the big cobalt 60 sources we use and HOLY gently caress do you yanks have the most comically inept regulatory framework. Guy was just testing it in a parking lot with no signs or barriers (or experience or knowledge for that matter) and sending massive high energy pulses right at a trailer park about 60m away. I'm told in most states you can acquire your own fuckoff death ray tube and all you have to do is pay a minuscule registration fee (and these clown flat out told us they never bothered registering theirs). Needless to say, we didn't purchase anything from those cowboys.

JoelJoel posted:Industrial radiography. Looking for embedded conduits in a thick slab of concrete that night. Ok, I can see using a source that large for that sort of work. We used to have 20,000 curies of Co-60 in a hot cell, but the water tank it was stored in sprung a leak and it was too expensive to repair so we just got rid of the source. Elsewhere in town is a gamma irradiation facility ( the GIF) that has enough Co-60 to produce over 1,000 rads/sec.

JoelJoel posted:And you thought my puny double digits ci source was scary? Jesus. It's one thing to have a source out in the open, it's another entirely to have it in a concrete vault behind a 10,000 pound door while you use manipulators to work with it. The GIF is for things like testing how well military equipment will survive nuclear... events. You can actually drive a full size tank into the chamber.

We know the meat inside it won't last, but afterwards can you go recover that stuff and have it be driveable? They also test circuitry that will be spending a lot of time in places where there is a lot of radiation and we need to be sure that the circuitry will still work. They also rent the facility/have agreements with universities to do various experiments there. If you are working on a PhD at any one of several universities you can request the use of the facility to do your experiments. The same goes for a number of other facilities there, they have a low dose facility, a research reactor with a high power level, and I guess you could do ride along experiments in other places as long as you aren't disrupting operations.

Not suicide per se, but one of my instructors who's been in radiation safety, etc since maybe the 70s told us about a research student/scientist who, while working on a project using lethal doses on animals and recording the results, decided he had to know what it felt like. He bypassed all of the interlocks and other safety devices one night after everyone was gone and sat there with a recorder as he gave himself a lethal dose. Can't find a proper link or anything from my phone.

REMEMBER SPONGE MONKEYS posted:My ignorance, then. Only ever looked from the human safety side and industrial uses with small sources - don't know microchips, etc. well enough, it seems. It's a facility at a national laboratory. Even if I know some of the stuff they do out there from the various seminars and presentations they give, most of their work is probably weapons related and therefore they don't talk about it. Circuits for nuclear weapons have to live in close proximity to nuclear material, and we drat well want to make sure they work. Beyond that, I'm not 100% sure of anything. Fun story about the GIF, though, involving a government auditor. At some point an auditor came out to take a look and various parts of the laboratory and try to track down missing things here and there. Cobalt 60 has a half life of 5.28 years. So when you have 20,000 kCi worth of inventory to start with, after 4 years or so you're down to probably around 12,000 kCi. So this auditor comes out and is trying to track down things that have gone missing over the years. He looks at the starting inventory, 20,000 kCi, and sees that the current inventory is now only 12,000 kCi. He's a money guy, not a nuclear guy, so he comes to the facility manager and very seriously asks him where the hell the other 8,000 kCi have gone. "How can you lose 8,000 of these things in just 4 years?" They had to sit down with him and explain how radioactive decay works, and where all that stuff went.

If the tank is airtight and the radiation dose is large enough then the meat may last very well indeed. Almost perfectly preserved.

Especially if he knew how dangerous those 8000 things could be. Luckily it's a fairly easy concept to explain, although I've never heard of a financial auditor getting into that sort of thing.

They also test circuitry that will be spending a lot of time in places where there is a lot of radiation and we need to be sure that the circuitry will still work. For historical reference, the Georgia Nuclear Aircraft Lab right outside Atlanta used a completely unshielded megawatt nuclear reactor to do that kind of thing back when they were thinking of making a nuclear-powered B-36. Reactor was on an elevator, normally kept in a pit in the ground, and you'd raise the elevator to irradiate your test samples and the surrounding area. They found that, among other things, it would turn the rubber in the tires brittle and hard and turn hydraulic fluid cloudy and thick. Among other things.

Yeah doesn't ionizing radiation do weird things with crystal lattices, like messing up some of the bonds? I think it can make some materials harder but more brittle?

Generally speaking a hard material is a brittle material (as opposed to soft, ductile). Edit: radiation can increase the defect density in a lattice which inhibits deformation.
