Abstract: Targeted Alpha Therapy (TAT) is considered an evolving therapeutic option for cancer
cells, in which a carrier molecule labeling with an α-emitter radionuclide make the bond with a
specific functional or molecular target. α-particles with high Linear Energy Transfer (LET) own
an increased Relative Biological Effectiveness (RBE) over common β-emitting radionuclides.
Normal tissue toxicity due to non-specific uptake of mother and daughter α-emitter radionuclides
seems to be the main conflict in clinical applications. The present survey reviews the available
preclinical and clinical studies investigating healthy tissue toxicity of the applicable α -emitters
and particular strategies proposed for optimizing targeted alpha therapy success in cancer patients.
