Radioisotopes of lead have been extensively utilized in interdisciplinary research across nuclear science, healthcare applications, geology, and environmental science since the last centuries, serving as the interdisciplinary bridge connecting different disciplines. Due to the rapid development of nuclear medicine in recent years, the lead-203 and lead-212 radioisotopes have shown significant potential for cancer theranostics, with the ability for accurate diagnosis and effective treatment of tumor. Lead-202 and lead-205 are key components of uranium-lead spikes, which are widely applied in geochronological research on the isotope dilution mass spectrometry (ID-MS) for uranium-lead (U-Pb) dating. As a member from the decay chain of uranium-238, the behavior of lead-210 has been considered as a key mark in sediment dating, atmospheric aerosol transport phenomenon investigation and the monitoring of potential leakage of nuclear fuel from nuclear facilities. However, the production of the above-mentioned lead radioisotopes remains highly challenging, and the current supply is not able to meet the growing demands of these lead radioisotopes across various research fields. In this review, the application of a few selected lead radioisotopes in interdisciplinary research is summarized, with a focus on the production and purification methods for the lead radioisotopes. Finally, insights into prospects for the production and utilization of key radioactive lead isotopes in the future are given.
