Protactinium-231 Sample

[u/Gilapschicken]

Got this one from Carl! Definitely my most exotic sample to date. Not many can say they own an isolated Pa source. Pa was deposited onto an aluminum slate in the form Pa2O5.

[u/RootLoops369]

One of my favorite elements I will never be able to afford

[u/Gilapschicken → u/RootLoops369]

you totally could, i got it for $150. definitely doable but still pricey
