Thorium-227 is used in targeted alpha therapy, where its strong alpha emissions are directed specifically at tumor cells using attached antibodies or ligands. Its decay produces additional short-lived alpha-emitting daughters, contributing to the therapeutic effect. Thorium-228, while less commonly used clinically, is also an alpha emitter and is mainly relevant in production chains and research settings related to alpha-based treatments.
