I have some marbles and a crucifix ( that kind you hang on a wall) made of this material. I inherited them from my grandmother , the marbles was intended to be toys. The crucifix also is visible in the dark and it's the object with major emissions, but nothing dramatic. The marbles emit mostly alpha rays. Both can excite notably my Geiger counter, but, storing them in a metallic box, (i.e. that sheet metal box for bi…

So the crucifix is visible in the dark? This article makes it sound like a black light needed to observe the phenomenon, which strikes me as odd because I wouldn't have thought black lights were commonly available at the time when these first gained popularity.

Couldn't you just measure background radiation?

My device, as other implementation, use the particle passing through the Geiger tube as a "virtual coin" , given a sampling frequency, if one or more particles are detected the firmware returns 1, if no particle is detected, zero. In other words, the random numbers are built a bit at time. My configuration with the background radiation returns too many zeros, so I needed something more ... lively. Anyway, what is the point to use the natural radiation if you have the serious stuff ? :-) When I say that the device is a nuclear RNG, peoples smile but when I turn it on and they listen the characteristic sound of a Geiger counter, the average reaction is "WHAAAAAATTTT ????". It's funny.

Maybe your grandmother purchased them from Bob Lazar: https://unitednuclear.com/index.php?main_page=product_info&c...

Do you have a link or project site for the DIY random number generator? I'd like to read about it :)

I thought this might have been an article on turning nuclear waste into glass (vitrification). Might be of interest to some people especially given current questions/challenges regarding reclassifying nuclear as "renewable": https://mo-sci.com/vitrification-nuclear-waste-management/

Nuclear is “clean” energy in terms of generating minimal waste compared with natural gas, coal, hydro etc. It’s not technically renewable but it’s widely available enough to the point that it could power our civilization for a good long while. Enough time that fusion should become feasible which technically isn’t renewable either since there’s a finite amount of hydrogen in the world but should be enough to see us through building a Dyson sphere of some kind.

Related: Fiesta Ware. Maybe worth going through the thrift store with a Geiger counter. https://www.thoughtco.com/how-radioactive-is-fiesta-ware-608...

Looking around ebay for a geiger counter and found this post, which includes some pieces of Fiesta Ware as a test source.

The crucifix is different, besides the Uranium glass it has engravings painted with something I think is tritium.

I was thinking to make it public, but it's based on an Arduino shield I purchased the day after the Fukushima accident, it is no more in commerce. I should make it more generic changing hardware. I think you can find online similar projects.

One of my favorite YouTube channles, Nile Red, has a cool video showing how to make Uranium Glass: https://www.youtube.com/watch?v=RGw6fXprV9U

Ads every 2 minutes, host has zero personality and seems to have no real understanding of the safety issues he's dealing with. Not for me...
