Abstract
Introduction: Radioactive isotopes of lead occur in the natural radioactive decay series and have been used as tracers since the early days of radiochemistry. These are 210Pb (t½—-20·4 y, radium D), 212Pb (t½—10·6 h, thorium B) and 214Pb (t½—26·8 m, radium B) all of which are separated from naturally occurring decay products of radium or thorium. There are in addition to these a number of other radioactive isotopes of lead which can be produced artificially with the aid of a nuclear reactor or a charge particle accelerator (Table 1).Keywords
