Lab did it. Came back at 15.
I would guess depriming and dry polishing are the culprits.
Ingot making is always done outside with a breeze blowing and casting is done inside with a hood <3" above the pot and exhausting the fumes out of the shop.
Time to rethink the depriming and the polishing hygiene.
Do that for a year and get retested.
As near as I can tell, a 15 is a level to be concerned about, but not go into panic mode at 66 years old.
