It generates lead 210 which has a half life of 223 years thus, during the extraction process, lead contains lead 210, whose quantity decreases by half every 223 years therefore, its content is virtually undetectable after about 130 years. So lead 210 dating worked well for the living corals, but was inappropriate for the much older dead corals carbon-14 dating would not have been useful for corals only a few years old, but does work well for organic material that is thousands of years old.
