Bismuth-213 ( Bi) has a half-life of 45 minutes and decays via alpha emission. Commercially, bismuth-213 can be produced by bombarding radium with bremsstrahlung photons from a linear particle accelerator, which populates its progenitor actinium-225. In 1997, an antibody conjugate with Bi … See more Bismuth (83Bi) has 41 known isotopes, ranging from Bi to Bi. Bismuth has no stable isotopes, but does have one very long-lived isotope; thus, the standard atomic weight can be given as 208.98040(1). … See more 1. ^ Bi – Excited nuclear isomer. 2. ^ ( ) – Uncertainty (1σ) is given in concise form in parentheses after the corresponding last digits. See more WebThe 0.3 microCi dose of (213)Bi on both the C6.5K-A and NM3E2 scFvs resulted in similar anti-tumor effects (p = 0.46) indicating that antigen-specific targeting was not a factor. This suggests that the physical half-life of (213)Bi may be too brief to be effectively paired with systemically-administered diabody or scFv molecules.
