@appassionato It's too bad the U.S no longer cares about scientific literacy. Separating 0.93% #Uranium to 3.5% for power plant use takes a lot of work. Separating 50% #U235 is relatively easy. Getting it to 90% is hard work again.

All of this mess, eventually boils down to #Uranium enrichment and the geopolitics of it. So here is an explainer.

Uranium Enrichment: Geopolitics Explained

U-235 and the mad rush around it.

What nonsense!
Natural uranium has 0.72%
of #U235 while depleted uranium has 0.3% of #U235
What has exploded in town of #Khmelnitski to the West of #Kiev,has been an ammunition store but it does not appear that depleted uranium there was in powder form of dust, so I doubt that a radioactive plume has been released.
If something has been detected over #Poland, it must be a smell of someone's fart
And yes,#uranium is #toxic
Both #uranium235 and #uranium238 are #radiotoxic
