Thehuman internal dosimetry of the radionuclidic impurities of samarium-153 in a new bone-seeking radiopharmaceutical, Sm-1,4,7,10tetraazacyclododecanetetramethylenephosponic acid (Sm-DOTMP), has been estimated from preclinical data. The effective dose from the impurities in lower-specific-activity Sm is less than 17% of the effective dose from pure Sm-153. It has a background-equivalent radiation time for a dosage of 37 MBq/kg of less than one-half year.
从临床前数据估算了新型骨骼靶向放射性药物 Sm-153 中放射性核素杂质的人体内部剂量。低比活度 Sm 中的杂质所致有效剂量小于纯 Sm-153 的 17%。对于 37 MBq/kg 的剂量，其背景等效辐射时间不到半年。
