A bit of trivia: When a Soviet submarine ran aground near Stockholm in Sweden, the Soviets claimed that the radiation measured by Swedish inspectors on the outside of the submarine came from the crew's radium painted wrist watches and not from nuclear weapons onboard.

That was the "Whiskey-on-the-rocks" incident near Karlskrona (not Stockholm). The soviet Whiskey-class submarine S-363 hit a rock and had to surface in the archipelago outside Karlskrona, where a very important Swedish naval base was and is located. S-363 lay stranded for 10 days on the island of "Senoren" (I had family there). What Wikipedia does not tell is that this part of the archipelago was not only "swedish waters" and only 10 km's from the naval base, but was actually a "military zone". Even on the civil islands inside the zone, and in the waters surrounding them, only Swedes were allowed, so as Danish we were not allowed to visit our family there. When we did anyway (in a Swedish family members car), we totally "shut up" when near other people so that nobody would take notice. So the Soviets were absolutely not allowed in this area - it was a military zone.

In case anyone is confused by something traveling faster than light, it's because the speed of light in a medium like water is slower than in a vacuum. So, basically the charged particles being emitted by the radioactive material are traveling faster through the water than light could and their interaction with the water at that speed is what causes the blue glow. Pretty cool!

Even tritium is no longer that popular, because it basically makes for relatively bulky markers. Other materials, like Luminova (and its successor, Super Luminova) have become the norm; they're not radioactive or toxic, but they rely on being "activated" through exposure to light. Then, when you put them in a dark place, they glow, but the intensity and the duration seems to depend on the size of the luminous marker and the amount of luminous material deposited therein. For instance, the lume on a dress watch like the current Longines Flagship glows for about ten minutes after having spent a few hours in the light.

Real radioactive glows are blue… (due to Cherenkov radiation). This occurs when a charged particle exceeds the local speed of light (the speed of light in a vacuum is constant - it varies in pretty much everything else).

When WW2 military plane instrument dials and electrical parts were scrapped by the Rosyth navy dockyard in Scotland, many of the radium dials were dumped along the coast nearby, notably and scandalously near the public beach at Dalgety Bay in Fife, which was contaminated by radioactive particles (even a microscopic particle, if ingested, can cause cancer). The beach has been shut for many years and clean up work finally started in 2021.

The radiation was ionizing one of the elements in the air. Oxygen or nitrogen I forget which one is blue though

American, here…. Night sights on a firearm are typically outfitted with a couple of atoms of tritium and a phosphor. The electrons emitted in the radioactive decay of the tritium causes the phosphor (usually zinc sulfide) to glow.

Just south of Albany, Georgia is a small town called Radium Springs. A natural spring there pulls up water from underground aquifers through rocks that have a high concentration of radium. A resort hotel was built next to the spring and it was advertised as a health resort during the heyday of "radioactive medicine." Today you can visit the spring, but they don't let people swim there anymore obviously. The spring flows into the Flint River and then on to the Gulf of Mexico.

Whaddya mean The Simpsons is a less than reliable source for what the radioactive glow resembles?

The beta particles that tritium emits are not able to penetrate your skin so its considered safe as result unless you actually ingest them. Alpha particle sources like radium on the other hand punch right through and go on to damage internal tissue so they are harmful just by being close to it.

@countzero1136

@@alexisrivera200xable beta particles can penetrate your skin but can't penetrate the glass that the tritium is contained within. alpha particles (such as those emitted by plutonium) cannot penetrate skin though which is why plutonium in its basic metallic form is pretty safe to handle. The problem is that its surface oxidises rapidly and forms a fine dust which can be ingested either through food intake with contaminated hands (gloves are definitely in order) or by breathing the dust. Once inside the body, the alpha particles can and do wreak havoc on the soft tissues, usually resulting in various cancers and other chronic conditions

As long as the glaze is intact, that's fine. The alpha radiation won't actually do anything to the water. It's just helium. Glassing up nuclear waste (pottery glaze is a kind of glass) is actually one of the proposed ideas for making spent nuclear fuel uneconomical to turn into a weapon or even a dirty bomb.

Probably off the back of uranium fluorescing under blacklight. This was probably the firs demonstration of it back in the day. New and media picked it up. A bit like people thinking if you stick a rag in a cars fuel filler and light it the car will explode.

I watched Kyle Hill's video about the "Demon Core" yesterday, which led me to find and watch the movie Fat Man and Little Boy. There's something really fascinating/spooky/macabre about the Cherenkov Radiation and critical mass... From the Radium Girls to Hiroshima and Nagasaki to The Tsar Bomba... Some say the world isn't over until the Sun rises in the West...well folks, there it is...

One small issue - the photo of shown of sabin von sochocky is in reality an 1865 picture of the Russian chemist (and famous composer) Alexander Borodin (right down to the bowtie). There's only one other picture of von Sochocky that a Google search turns up (in a magazine article authored by himself). There seem to be a lot of Borodin as von Sochocky pictures out there - lesson: once inaccurate information enters the web it's impossible to correct.

The witnesses from Chernobyl said that after the top of the reactor blew off, there was a beam of blue glowing light, so… 🤷‍♀️

Greetings, Uranium glass was regularly used in the making of glassware in the old days. It was first found in a yellow-green glassware sold under the name of Vaseline glass in the late 1920s and early 1930s. The glass glows bright green under a black light, indicating it contains uranium. I collect Jadeite glassware. It was a very popular color of a type of Depression Era glassware. At least three or four popular glass companies produced and sold it. It is a beautiful pistachio colored glass still prevalent in Antique Shops. During the Great Depression, they sold entire lines of Jadeite kitchenware like mixing bowls, salt&pepper shakers, storage containers for sugar, flour, tea, &etc. Fire King sold several patterns of dinner plates, cups&saucers, vases, &etc. Early Jadeite also glows green when exposed to a black light. The very first Jadeite piece I bought was a very large and thick mixing bowl which fitted a 1915 electric mixer I bought. Its original aluminum 3-bowl set was long gone and that heavy Jadeite mixing bowl was the only thing in the antique shop that would fit the mixer's "lazy Susan" base. Well, I was soon "infected" by Jadeite's charm. I was hooked and bought a lot of the stuff since! Depression glass was a cheaply made product that was affordable, yet pretty, and was sold during the Great Depression. Its production quality would not pass muster in today's quality control due to flaws in the glass making process of the day. As a collector, that is part of its charm. Jadeite was also given away as a premium in bags of flour and oatmeal at the grocery. Movie theaters often gave away sets of dinner plates as a gift. An encouragement to come to the theater. Going to the show was a luxury during the Great Depression. Jadeite has a fascinating history. Despite the obvious uranium content in Vaseline glass and some Jadeite, it is completely safe to handle and eat off of.
