>Landa and Councell evaluated the leaching of uranium into different solutions over a 24 hour period. The glassware they used was designed to hold liquids (e.g., drinking glasses). They determined that the average resulting concentrations of uranium were 0.052 ug/liter (1.7 x 10-11 uCi/ml) for water and 5.9 ug/liter (2 x 10-9 uCi/ml) for acetic acid. The highest measured concentrations were 0.63 ug/liter (2.1 x 10-10 uCi/ml) in water and 30.1 ug/liter (1 x 10-8 uCi/ml) in acetic acid. They noted that less uranium would leach into solution when the experiment was repeated. The presumed explanation is that less and less leachable uranium becomes available.
According to the WHO[0] the tolerable daily intake (TDI) for uranium is 0.6 µg/kg body weight per day. So, 42 µg/day for a 70kg/150lbs person.
Worst case scenario for drinking 5l of water daily from those glasses would give oral exposure to 3.15 µg in total. Even if you were for some reason a vinegar enthusiast 1l/day would leave you with "only" 30µg.
Maybe you want to err on the side of caution and don't try pickling with those.
