Slugnoid posted:This reminds me of an old story I heard at work years ago. Two old ladies that lived next door to each other, both roasted in their showers by a current that managed to travel through the lights into the rebar in their shower floors and then through the wet tiles into their bodies. That certainly is an unfortunate chain of events. A builder fires a nail into the floor, inadvertently penetrating the lighting conduit. Someone later hooks up a washing machine but leaves out the sealing washers on the water hoses. This leaking water soaks into the grouting on the wet room floors, making them conductive enough, in combination with the wire reinforcement, to energise the floor, but only when one of the garage light switches is in the "on" position. The occupants of the two units are then killed when touching the shower fixtures while standing on the energised floor. It makes you wonder how long the floor had been in that conductive condition before the switch happened to be in that position when the victims tried to shower.

Thankfully nowadays you wouldn't get an occupancy permit for a house without a safety switch or the concrete slab being earthed, but in older houses you just never know whether there's 240 volts flowing through the rebar under your feet lol.

I think I was meaning to ask if it was normal for it to be glowing red hot? Did it just come out of the plutonium furnace or is it hot because of radiation?

Radiation, and also pure plutonium ignites in the presence of oxygen. Could be one or the other or both. Plutonium 238 in particular heats up from radiation. Green associated with radiation comes from old radium watches and other consumer devices. The green glow actually comes from phosphorus which glows green in the presence of radiation.

That's Pu238, which is used in radiothermal generators and has a power of about half a watt per gram. Pu239 has a half-life about 300 times longer and self-heats about that much less.FogHelmut posted:Radiation, and also pure plutonium ignites in the presence of oxygen. Could be one or the other. A big solid chunk of plutonium isn't going to ignite in the atmosphere. Chips, turnings, powders of it can ignite, but the same can be said of aluminum or even iron. You need high surface:volume ratios for that to happen. Phanatic fucked around with this message at 20:33 on Mar 9, 2021 |

They use this cool property of plutonium to make really long lasting compact and durable power sources for satellites too. ^^^

A big lump of metal isn't going to be pyrophoric, only small fragments, and you don't find those in a bomb. You do find them in nuclear weapons production facilities where they have caused serious fires. https://www.osti.gov/servlets/purl/5156223 Phanatic fucked around with this message at 20:36 on Mar 9, 2021 |

Right on topic, check out Harold McCluskey, survivor of a plutonium accident at Hanford in the 70's and often called the most irradiated man alive or something. He was working in a glove box which exploded and embedded radioactive glass and Americium into his body. He lived for quite a while after.

Zudgemud posted:Also, the railroad crossings along that road have previously had trains come without the warning lights flashing too. Back when I was getting my license, the instructor (an awesome older guy who had been running a driving school with his wife for ages) gave me the best driving advice I have ever gotten: "With crossing lights, always remember that they were ordered from the cheapest possible manufacturer by a poor and penny-pinching country". Never trust the lights with your life, always take the time to look.
