Samarium-153-EDTMP (ethylene diamine tetramethylene phosphonate), for its promising biological properties, has been proved as a palliating therapeutic agent for bone tumor in human beings. ¹⁵³Sm with high radionuclear purity and specific activity of 5.18 GBq (140 mCi)/mg Sm₂O₃ was prepared by irradiating natural Sm₂O₃(¹⁵²Sm, 26.7%) sample, replacing costly enriched samarium oxide target, at a flux of 4x10¹³n·cm^-2·s^-1 for 110h. The yield of ¹⁵³Sm complexing with EDTMP is greater than 98%at pH 8〜10 in boiling water bath for 30 min, and not significantly decreases within one week after ¹⁵³Sm-EDTMP complex formation.
