Radioisotopes that decay by beta-particle (negatively charged electrons) or alpha-particle (helium nuclei) emissions are selected for these radiotherapeutics as they can deliver lethal radiation to tumor sites during their radioactive decay. The molecular carriers, such as monoclonal antibodies or peptides, target a specific site on a tumor cell and are designed for high tumor uptake. The radioisotopes are bound to the carrier molecules with a chemical linker to ensure the radionuclide remains attached to the molecule in the bloodstream and is carried to the tumor site to deliver their therapeutic dose. The graphic below demonstrates this process.
