If you're interested in the process and chemistry behind it, it's a very informative and entertaining watch.
It doesn't glow by itself, and it is unrelated to radioactivity. It's just fluorescence under a blacklight.
That being said, you shouldn’t be eating or drinking from it. If pieces chip off and get inside your body, that can be bad.
I wonder if uranium glass was actually the inspiration for the neon green elements in these pieces?
As a kid? Now as an adult with disposable income, I can get really awesome LEGO sets, sets I really enjoy building. I prefer Technics, but also have several star wars sets, including the model death star (not the one with the minifigs) and the original 32" star deatroyer. Post Christmas this year was spent building a lot of LEGO City sets.
I also have the Saturn V and ISS sets, both of which are awesome.
Those lenses have good metal encasing and the radiation is so small that there’s no real problem except the lenses start to turn to yellow with age.
That type of glass was mostly only used in older lenses - which with the right adapter they still work great on modern cameras!
Not because the radiation it emits while intact. Alpha radiation is the primary form of U238 and it does not penetrate skin. But the chip and wear in everyday use means that you get particles inside your body. Alpha radiation inside body is bigger risk and uranium is also toxic and reproductive toxicant.
The largest radiation hazard in home is radon gas in indoor air. If you live in an area with lots of radon emissions it's good idea to have ventilated crawl space under the house.
> Do not use ceramics like antique orange-red Fiestaware or Vaseline glass to hold food or drink. They can chip, and you can ingest particles of uranium with your food or drink.
>Dispose of any broken radioactive antiques. For instructions on proper disposal, contact your state or local radiation control program.
They stopped making it in the 1970s but you can still find it floating around somewhere online.
I inherited them from my grandmother. Should I be worried about having used them for years?
You'd need about 100,000 µSv/year to get heightened cancer risks.
Uranium is also everywhere in ppm quantities.
But as long as it's intact, no big deal. (I guess, I'm not an expert, why are you listening to me?)
Here's an article, though I heard about this from the Hawaiian Pizza episode of The Anthropocene Reviewed.
Edit: Acid leaches lead, not acid. Misuse of 'leech' preserved for posterity.
English is such a trip!
There were so many glass companies from Virginia to Ohio and most dabbled in this for a run or two so good examples are easy to find on ebay cheaply. I found the more solid pieces to be best for the light effect.
