I can kind of make that out, but man that would mean that even if the driver of the first one was quick enough to jump out of his cab in time to avoid getting smashed by the second train, he'd have to had dodged a whole new wall of death coming at him from behind. gently caress.

Looks like a speed rack/baker's rack. It's on wheels and really lightweight and easy to move, so not really that unsafe at all. I mean it's not smart to block one of the extinguishers with it but a child could move it out of the way with ease, and they almost definitely have other extinguishers around, and ceiling mounted fire suppressors if it's near anything that could catch fire. I've had fryers catch on fire at work before and they're really easy to put out. The powder we mix in with the oil to filter it also works to put out grease fires, and we have a big box of it right there. I've been here four years and we've never had to activate the Ansul system despite most new hires setting something on fire at least once.

Strange woman, can't remember if she has been featured in this thread or not. https://www.youtube.com/watch?v=9LN2V4DsP0s There were radioactive firefighter uniforms in the basement. She said that people took the firefighter helmets as souvenirs. I guess removing a small clothing fragment for analysis isn't quite so bad. And yes, what she's doing is pretty dangerous. My biggest concern would be getting a hot particle on my skin or worse, inhaling/swallowing one.

Is she a scientist documenting this stuff for some sort of official organisation or something? Also, this is another Chernobyl documentary that came up in the suggestions with more original footage and interview with surviving roof workers: https://www.youtube.com/watch?v=lNc4MvI2s08 Some bullshit numbers in there but yeah good footage as well. [edit] loving hell, those interviews get more and more harrowing as they get more recent. Munin fucked around with this message at 02:20 on Jun 2, 2015 |

I'm trying to figure out how much exposure she's getting and how much it's likely to gently caress her. So just in that video, the hunk of radioactive graphite she dug out of a radioactive ant hill () reads over 100 mSeivert/hour. One seivert seems to be associated with a 5.5% chance of eventually developing cancer, so every hour she handles that part of an exploded nuclear reactor ( ) she increases her risk of developing cancer by .5%, and receives more radiation than an astronaut on the ISS does in 6 months. And that's just the exposure from that pebble. To mitigate that, it looks like calculating radiation exposure considers whole-body vs. partial exposures, but this being gamma radiation, isn't she basically getting a full body dose just having that so close to her? I can't imagine those gloves or even the tissues of her hands are stopping anything from whipping right through the rest of her, but I have no idea.

Yeah that's the part I'm totally unsure of, and the effect of the size of the particle and its distance from her. Those sure look like big scary numbers on the meters, but I don't know how quickly that intensity drops off - she mentions the inverse square law in that video when she's talking the "marketing guy" into coming closer so I have to think that unless she's just completely nuts she must effectively be receiving a much lower full-body-equivalent dose.

Well, she's not wrong about the inverse square law, but if the meter is reading a certain level and she's standing right there that's the dose she's getting. And gamma will rip right through you, so a hand isn't going to block poo poo (not only that, it will radiate out in all directions). It takes inches of lead (or feet of concrete) to block gamma particles --your body is nothing but tissue paper to them and will pass through you like tiny little wrecking balls.

Gammas are penetrating but not that bad from a biological standpoint, because since they're uncharged and massless photons they don't have a big interaction cross-section. If they *do* smack into a DNA molecule they will do bad things, but the odds of a given gamma actually interacting with you on its way through is pretty low, all the more so since they're high energy and thus have tiny wavelengths. The way you get equivalent dose is by taking absorbed dose and multiplying it by a weighting factor based on the type of radiation. For gammas, the factor is 1; one gray absorbed dose = 1 sievert equivalent dose. Same thing for betas, x-rays, etc. For alpha particles, that factor is 20, because an alpha is massive and large and highly charged and is guaranteed to interact with something; this means they're not highly penetrating and won't make it through skin, but that's also why alpha emitters that get inside you do very bad things, every single one emitted is kinetically or chemically reacting with something, probably kicking off a whole cascade of free radical formation and breaking a bunch of the chemical bonds that keep your cells alive. Taking one gray of alpha radiation = 20 sieverts = you gonna die. There's a little quiz question: Pretend you have four radioactive cookies. One's a pure alpha source, one beta, one gamma, one neutron. You can eat one, stick one in your pocket, throw one away, and hold one in your hand. What do you to do minimize your equivalent dose? You hold the alpha source in your hand, because your skin's blocking most of it and if any make it through you want it as far away from your vital organs as possible. Stick the beta cookie in your pocket. The gamma source, unless you can throw it really far you might as well eat it because it's not going to make a difference so far as how much of a dose you wind up with. And throw the neutron source as far as you can can because those are almost as bad for you as alphas, but much more likely to penetrate your skin.

Even the liquidator helicopter pilots who knew 100% that what they were doing would kill them, but were doing it to protect everyone else. I have a book called Voices of Chernobyl and it's heartbreaking and soul-destroying to read. Stories of liquidators, their partners, survivors and Prypiat residents.  Reztes posted:I'm trying to figure out how much exposure she's getting and how much it's likely to gently caress her. I would imagine (totally uneducated guess) that she's gonna get hosed up in some way. The Soviets made a huge exclusion zone around Chernobyl due to the poo poo there, so loving around in a known highly radioactive area can't be a good thing, let alone digging up parts of the exploded reactor and screwing around with it. Gotta be crazy, what possible good comes from doing that stuff??? Phanatic posted:There's a little quiz question: Pretend you have four radioactive cookies.

uPen posted:Better than working at the Hanford site and dying of cancer when you're 50 because management told you to throw that cardboard box full of radioactive waste in a ditch. Sounds similar to what the liquidators went through. "Okay guys, good news for you! All you have to do is go up to the roof, pick up a big ol' chunk of graphite, and throw it in the hole in the roof! That's it! Do that, and then you're done for the day and can go home early!" (Never mind that in the few minutes you're on site each day far exceeds the safe daily dose of radiation and you will almost certainly die from some horrendous form of cancer or radiation poisoning.) uPen posted:e: I wonder how you get health insurance when your job is digging up radioactive, toxic materials for youtube videos.

The human body is calculated as water for radiation purposes. the tenth thickness for water is 24 inches, so it wouldn't lose very much energy at all. Not to mention that depending on your distance from the source you're being blasted with radiation from all over the place.

Usually the justification is either "it's worth it" or "the bad part won't happen to me". She under stands the risks, and seems to really enjoy hunting down bits of reactor core that max out every meter her team carries. I wouldn't be surprised if part of her justification was along the lines of "doing this for x years increases my chances of getting cancer from 65% to 73%" and she's ok with that. It's not like she's doing something as dangerous as smoking, riding a motorcycle, or roofing work.

No, and that's incredibly irresponsible if you ever use/store them as such with the caps off. The chain is to stop them from falling over, which is by far the easiest way for the valve head to get smashed off and turn the tank into a torpedo. Welding caddies almost always have chains on them, and the caddies themselves basically facilitate tank theft, so it's not that. In the blacksmith's shop I worked in every caddy or torch work area had eye bolts and chain in the wall so you'd never be in a position to use an oxygen tank where it was free-standing and unsecured. The caps are durable as hell but a bad enough fall or mishap can still damage the valve with one on so, yeah, they really should be chained up or caged as much as is possible.
