We produced At-211 by irradiating the semi-sealed encapsulated Bi target with an external vertical beam. At 28.5 MeV, the yield of At-211 was 22 MBq/mu A h (600 mu Ci/mu A h). At-211 was recovered by dry distillation, and 80% of the produced At-211 was successfully obtained in dry (NaAt)-At-211 form within 2 h from the end of bombardment (EOB). The radionuclidic purity of At-211 was >99% at 5 h from EOB. (C) 2014 Elsevier Ltd. All rights reserved.
