【Abstract】 A method of preparation of standardized radioactive ⁴⁶Sc solution is developed. The separation of ⁴⁶Sc, the composition of ⁴⁶Sc solution and Its stability, and radioactivity measurement of ⁴⁶Sc are systematically studied. The results obtained in the study and in the applications in many laboratories have shown that our method is effective and reliable.更多还原
