@oralloy,
beneficiation by HF is no longer a "liquidus" process. All UF6 is made worldwide by anhydrous HF, which is totlly recycleable and is therefore captured. HF leaks can occur but the discharges are kept within a High Mg peroxide " permeable environment".
ANYWAY, we get more fugitive HF if living near a plastics plant where they make PTFE ,Teflon or near any refinery where they do alkylation. You probably live nearer an HF emission source more common than making UF6.
Stop trying to be a drama queen.
We can sense emissions by several other key isotopes hundreds and often thousands of miles downstream and can tell what theyre doing .
Its not alchemy.
