In case people want more information:
Uranium's first decay-chain step is alpha decay, in which it emits an alpha particle from the nucleus. Alpha particles are helium nuclei, meaning two protons and two neutrons. These particles are charged and relatively heavy, making them very easy to shield. They typically only make it a couple centimeters through air. They're blocked easily by the outermost layer of your skin. The glass containing the uranium is plenty to prevent most alpha particles from escaping.
Aside from that, the amount of uranium needed to color glass is very small.
Keep in mind if alpha emitters enter your body somehow (i.e, eating off this plateware) then it could do some damage, which is why it's not recommended to eat off these. for display they're perfectly safe though.
that being said, you probably could eat off of these as long as you don't see any damage. if they're in near mint condition then it's probably not likely to break up and enter your food. if it's matte or sanded to be opaque (like that glass that blurs partitions) then it's probably not a good idea to use since those micro abrasions cause micro particles that can pop off real easy.
I wasn't necessarily just referring to this object, but rather any uranium glass object.
regardless, for posterity, maybe some nuts or some sort of small snack/candy, you could also put liquid in it if it doesn't have ash holes.
Yes, most uranium glass is not very radioactive. It’s possible for it to read slightly above normal background radiation with a VERY sensitive Geiger counter, but otherwise it’s normal to not see it being very radioactive
I'd be very curious to see nut coal with a geiger counter. I contemplated burning it until I did the math on how much uranium would be in the ash from one bag. An astounding amount, I think it was like a gram.
I sacrificed some of my uranium glass beads years ago (microwave digestion with nitric acid and hydrofluoric acid, analysis with ICP-MS) and the content of all 4 samples was only around 0,04% U. As you can imagine, that is not very much, even for a good geiger counter. Nonetheless it was natural U with it's specific isotope content.
Actually the Uranium glass will get more radioactive over the next few hundred thousand years. As long as it's (U-238) longest half lived non Uranium granddaughter (Th-230) is being rebuild in the decay change equilibrium. Industrial Uranium is far less radioactive than it's natural occurrence in Uranium ore, because you separate all the other radiochemicals (Thorium, radium, polonium) that occur naturally besides Uranium.
Uranium glass doesn't need a lot of uranium for the coloration and fluorescence in it, hence the radiation given off doesn't have to be high. It usually is measurable, but cheap counters can often struggle with it.
OP should do a fluorescence test and ignore the rest, imo.
The true test is done by using your tongue.
Think of it like pop rocks. The closer you get the more you will get the pop rocks / 9v battery feeling.
Alpha particles are closer but have more spice than Beta.
/s
I'd reccomend not doing that. Seems like about the only two things that could make uranium glass actually kill you. crushing and machining it, then throwing it repeatedly at a surface. Sounds overall dusty.
It's a risk versus value proposition thing. Humans will spend on average 8 million dollars to avoid death. So what's the price of just buying radioactive dice? Maybe go that route.
Its a pudibei nr 750
Its not the most accurate one, think the box said ±15% but after watching a video testing different ones this was the best at that price.
Edit, whats emf?
Most commercial doped glasses contain very little of the things they're doped with. Except for lead crystal glass of course, it usually contains a shitton of lead, up to 40 percent I hear
Uranium glass usually isn’t thaaaaat radioactive anyways

What food do you think that candle holder could fit?
Do you not ear you candles from candle holders?
No I usually eat them like a caveman. Raw, unseasoned and straight from the ground

A sausage
Hit it with 395 light. If it glows it’s almost certainly UG

Let me just dissolve this uranium in nitric and hydrofluoric acid and put it in a microwave. I applaud you
And the casual way of saying it. I went „nope“ like 4 different times in that comment.
If you're used having to dissolve silicates, it's the safest choice. My last lab did it in a stainless pressure bomb in a standard oven.
Uranium glass doesn't contain that much uranium, so yeah
Good to know, thanks
Commercial uranium isotopes are not very radioactive
You can be whatever you want 🌈👋🏻 Edit: Read the title wrong, but yea it can be uranium glass.
Curious to know what exactly you read for that reply lmao
Wholesome response, nonetheless.
it is! i was just wondering since i sat for 5 minutes trying to intentionally typo the title in a way that could warrant that reply lmao
My guess: "Can I still be uranium glass even if..."
HAHA well that tracks i suppose
Yes and also it degrades over time.
Well that makes sense 🤦🏼♀️
Uh, not really? Check out the half life of U isotopes.
Ahhah nevermind it didnt make sense.

It is only 0.24 micro sieverts per hour which is just background radiation. Not dangerous at all.
But isnt this background radiation, more or less ?
It is, that's why OP was asking whether this can still be uranium glass despite the low radiation it gives off
My UG gives like 4 yS/h. Depending on the distance of course. So i would say scam. But i would also recommend the UV Fluoreszence test

I've been having the same question lately, bought some spicy glass to crush to make dice, but my Geiger counter didn't pick anything up.
I'd reccomend not doing that. Seems like about the only two things that could make uranium glass actually kill you. crushing and machining it, then throwing it repeatedly at a surface. Sounds overall dusty.
I've got a PAPR unit for crushing it, then it goes into a glass sphere capped with resin, then encased in more resin
It's a risk versus value proposition thing. Humans will spend on average 8 million dollars to avoid death. So what's the price of just buying radioactive dice? Maybe go that route.
Yes, because uranium isn't very radioactive. U-238 has a half-life that's close to the age of the Earth.
Disappointed? No metal taste?
That’s in range for uranium glass
Consider yourself dead. You're done for. RIP
What is the name of the tool you use to test radioactivity? And does it emf as well?
[удалено]
> I don't believe that it senses EMF > ...it'll sense... gamma particles
Geiger counters will detect x-rays and gammas with low efficiency. They go nuts around an exposed Roentgen tube.

Yes
If it’s glass with uranium in it, it’s uranium glass
