UO2 question

[Oceania]

Hi Guys~!
A long time no see!


OK - small question.
Inadvertently inhaling up to 1 mg of UO2 over a 30 day period.
UO2 is set in a biological matrix fixed in a hardened resin that is trimmed.
Particle range respirable from 10 to 0.05 micron.
Estimated lung clearance of 90% of resin UO2 mix within 68 days ...

Any ideas on leaching of UO2 from plastic for estimated blood, urine, and general heavy metal toxicity?
