Despite the growing popularity of permanent implants using encapsulated125 I seeds, only two types were commercially available, Models 6702 and 6711. Recently, the Food and Drug Administration (FDA) approved a new type of125 I seed, Model 3631‐A, called IoGold (apparent activity 0.28–0.63 mCi). Due to the large demand for125 I seeds for prostate implants, IoGold seeds will be available in January 1998. In this paper, the basic properties of the IoGold seeds have been evaluated in comparison to the established Models 6702 and 6711.
