title: Comparative distribution on niobium-95 in maternal and fetal rats and rabbits.
abstract: Pregnant rats and rabbits were injected with Nb95 towards the end of gestation. In rats, all maternal tissues showed higher concentrations compared to the fetal organs; the highest ratio was 0.6 in bone. In rabbits a different distribution was found. The fetal bone exhibited a 3.5 times higher concentration of Nb95 than the maternal one.
