C-14 considerations

["Engelbretson, David A." <DEngelbret@tmh.tmc.edu>]

Dear Colleagues,

Would anyone know if there are any considerations when dosing a pregnant or
nursing woman with 10 uCi of Carbon-14 to diagnosis  bacterial overgrowth in
the GI tract?  Since dose activity is small and the effective half life is
about 10 days, I would initially think not but I could be incorrect.

Thank you for your assistance.
