Abstract

$^{211}At$ is an alpha emitting radionuclide, which can be produced using cyclotron with alpha beam. In addition, its strong linear energy transfer and iodine-like chemistry make that $^{211}At$ is one of the most attractive radionuclide in the field of targeted alpha therapy. In this review, production, labeling, and radiopharmaceuticals of $^{211}At$ will be discussed.
