Isotopes of Elements Heavier than Mercury

The isotopes of the elements that are heavier than mercury are all part of the radio­active decay series except At-211, which is produced in cyclotrons. The half-life of At-211 is 7.21 h, and it has alpha radiation. In addition, Pb-201 is produced from Tl-203 (Eq. (8.27)).
