What is Lead-207?

Plain description, key identifiers and synonyms

Lead Pb-207 is a stable isotope of lead (Pb) and the final non-radioactive product of radioactive decay in the actinium series (uranium-235) or plutonium cascade (plutonium-239), which both include the daughter radionuclide radium-223 (Ra-223). As Ra-223 is used to treat metastatic bone disease and Ra-223 decays to the stable isotope Pb-207, the concentration of Pb-207 found in bone metastases may be used to estimate the amount of Ra-223 that accumulated in the bone during treatment.
