Abstract: 89SrCl2 injection are prepared with neutron radiation reaction of 88Sr(n,γ)89Sr and asepsis technics, which radionuclide purity is not less than 99. 0%,radioconcentration is not less than 37 GBq/L, pH is in the range of 4. 0-7.5, aluminium content is not more than 2 mg/L and strontium content is not more than 12. 5 g/L,bacteria endotoxin content is less than 15 EU/mL and all the results of asepsis test are no growing up of bacteria. In corporation, the internal control standard of 89 SrCl2 injection is established according to quality status of 89SrCl2 injection.
