The gastrointestinal system can be pretty delicate... Yeah if you were somehow able to stave off the infection I assume you wouldn't really be eating solid foods for the rest of your life.

Fancy_Breakfast posted:I wonder what would happen if you were to fall into that. I want to see how fast radiation can mutate somebody. Water's a really good radiation shield. It's pretty dense so it's good for gamma shielding and it's got a lot of hydrogen in it so it's good for neutrons as well. https://what-if.xkcd.com/29/ PetraCore posted:Oh. I'm still just an undergraduate in biology and we didn't have any classes on radiation damage so I've mostly just heard about it in the mutating DNA and why that's very bad if it's happening a lot way, and the cancer stuff. The chief method by which radiation fucks you up is fundamentally chemical. It's possible for a particle of ionizing radiation to directly impact a DNA molecule and damage it, but it's unlikely. What's far more likely is for that particle to smack into something else in the cell, like a water molecule, and generate a reactive oxygen species, which then goes on to react in a chemical cascade that can break up additional molecules while everything tries to get back to a neutral charge. This can result in breaking or cross-linking DNA. And for some reasons, cells that are currently undergoing mitosis are far more vulnerable to that sort of oxidative stress. The end result if you're lucky is a cell that's fatally damaged and successfully triggers apoptosis, or if you're unlikely winds up as the root cause of a malignant tumor. So cells that rapidly divide as part of their normal lifecycle (like the stem cells in your marrow, the endometrial cells in your GI tract, your skin cells, etc.) are far more susceptible to damage and oncogenesis than cells like muscle or nerve cells.

Fancy_Breakfast posted:That's disappointing. I was hoping acute exposure to extreme amounts would result in somebody exploding or some poo poo.  Anatoli Bugorski posted:As a researcher at the Institute for High Energy Physics in Protvino, Bugorski worked with the largest Soviet particle accelerator, the U-70 synchrotron. On 13 July 1978, Bugorski was checking a malfunctioning piece of equipment when the safety mechanisms failed. Bugorski was leaning over the equipment when he stuck his head in the path of the 76 GeV proton beam. Reportedly, he saw a flash "brighter than a thousand suns" but did not feel any pain. A lot of places say that side of his face never aged, but it might have just never got wrinkled up because all the nerves were obliterated and so there wasn't really a lot of flex action.  you can't really tell because every pic i found has 98% artifacts and 1% image. The remainder I assume are loose protons but imo it does look like his left side looks a little younger. Prob just permanent botox. This guy got screwed over. If you take a hadron to the face or some poo poo you should be taken care of for chrissake fuckin beat but I had pics Asproigerosis posted:Theoretically, you can be exposed to so much high powered ionizing radiation that you are vaporized by the energy blowing apart the atoms of your body, but that's a cosmic scale type of event. You could get blasted hard enough to immediately enter shock and die I guess, but you'd probably need some favorable comorbidities to have that happen. I guess if you got beamed in the brainstem you'd potentally be pretty hosed pretty instantly.

PetraCore posted:Yeah, but at least IV nutrition exists. it sounds like the infection is going to start as soon as stuff starts sloughing off and the intestinal system is long enough and delicate enough there's not really a way to get in there and prevent that. I guess you could chug a gallon of antibiotics to try and kill it all before you lose your intestinal lining.

Sagebrush posted:There are doses of radiation that will kill you pretty much instantly -- thousands of Grays and up -- but they are levels that you're only likely to see from a nuclear bomb and they amount to just being hit with so much energy that you're barbecued alive. I recall reading in a book awhile back that supposedly immediately after Reactor 4 exploded a couple of engineers and technicians ran to the ruins of the reactor core to see what happened and search for the coworkers, and were absolutely fried from the radiation. They immediately felt weak, sat down in one of the stairwells nearby to rest, and never got back up.

Does anyone have a link to that crazy looking, but apparently safe, Russian welding practice where they join two big metal sections together by sprinkling thermite(?) along the seam, lighting it and it burns in a huge long line along the join but leaves an incredibly smooth weld?

That's not really crazy. When I was living in Munich, Germany all the tramways were repaired like this, by official policy. The even did a demonstration of thermite welding for schoolchildren once a year.

Even discounting any pharmaceutical knowledge gained, the systemic, scheduled starvation and rationing of subjects produced a non-trivial amount of dietary information, and also helped establish the current 2,000 calorie diet we have today.  Nazi "scientific methods" were extremely shoddy and produced junk. https://www.nejm.org/doi/full/10.1056/NEJM199005173222006#t=article 2,000 to 2,500 calories being needed to maintain an adult came from USDA food intake surveys, and even before the war "ideal" rations were sized in this range by governments and armies. Late in WWI for example, US soldiers got "reserve rations" which were 14 ounces of canned bacon or beef, 16 ounces of canned bread/hardtack, and 2.4 ounces of sugar, which works out to around 3100 calories but was probably less due to lower quality meats and worse canning technology. In WWII the K-ration was developed which had around 2800 calories. We can go further back to the American revolutionary war where soldiers were supposed to get 1lb of beef and 1lb of bread or flour a day, which I'd hazard works out to something like 2200 calories on the conservative side. They also received 3 pints of dried peas/beans or veggies and a half pint of rice per week, which works out to something like an additional 200 calories/day, plus a quart of Spruce Beer per day as a anti-scurvy thing but the beer would be another 50 calories. Plus whatever they were able to buy or loot/steal/forage. And again, we can go even further back: Roman soldiers got something like 1lb of meat and up to 2-3lbs of grain per day plus other supplementary foods.

None of them can swim, there's zero viability in the water and they're in a pocket miles from the entrance. They have the means and methods to keep them alive during the process but man it's going to be a very long few weeks.
