Make Glow in Dark Powder from Crushed Oyster Shells

This video was a gay waste of time. Thanks.

I'm trying to make a scintillator for detecting alpha radiation. Can zinc sulfide be used? Is there a compound that is better at detecting alpha radiation than zinc sulfide?

Thank you for your time.

@MOOMISS1 I know right it's so awee

yep but im gonna try it in my blast furnace. i havent used mine in a while and i didnt build it for nothing!

[panzuman]

sea shells are calcium carbonate correct? so does that mean pure calcium carbonate would work better? or is it a different chemical preasent?

@panzuman Well according to bit[dot]ly/cGs1mI (it's a link, put it in your browser where links go, it's like tinyurl for Twitter) there's lots of different compounds in them besides CaCO3.

@panzuman I thought the same thing and gave that a try... it gave almost no effect. I was using reagent grade calcium carbonate. it is my understanding that most glow in the dark compounds have to have some form of impurity that acts as an activator. For ZnS copper is the impurity. In this case I am not sure what the impurity is. In the future I plan to try some cheap chalk to see if I can get better effect. Thanks for watching!!

@myst32YT hmmm chalk.... ill try that as well ive got about 10+lbs of sulfer so i think im good lol

[myst32YT]

@panzuman yeah i would say you are good to go... ;-) Remember.. Red hot... if it does not work you probably did not get it hot enough long enough.

@myst32YT I wonder if it's magnesium or sodium. NaCl and MgSO4 are the two main components of sea water.
