One in 8600 parts of K is K-40 which is radioactive and even more than U-235. Due to its abundancy, K-40 is the most abundant source of background
radiation in nature.
But is it ever enriched ?careysub - 21-6-2016 at 11:25

Oak Ridge isotope sales used to list prices for the isotopes they prepare (using Calutron technology mostly) but now you have to ask for quotes for
everything.neptunium - 22-6-2016 at 03:25
Some chemical reaction favor one isotope or another.. Given how easy it is to access KOH for example it shouldn't be overly difficult .
But why K40? It has petty penetrating gamma why would you want to concentrate it? Just for curiosity?blogfast25 - 22-6-2016 at 10:29

The differences in chemical properties of isotopes of the same element ar vanishingly small. Which is why mostly physical separation is used, based on
small AW differences.
If you have any references on chemical separation of K-40 I'd be interested in seeing them.

This was the first one I found by googling potassium " isotope effect.
