I don't know how common it is today, but "way back when" we had a couple of
clearly visible encounters with the longer-lived contaminant.  In case you're
interested in an example retention time . . . Berger, C.D., B.H. Lane and T.
Hamrick, "Clearance of 202Tl Contaminate Following Intravenous Injection of
201Tl," Health Physics 45 (5):999-1001, 1983 . . . Watson, E., and C. Berger,

Administration," 23rd Annual Meeting of the Southeastern Chapter of the
