摘要：

225Ac was prepared by the 226Ra(γ,n) reaction on an electron accelerator (MT-25 microtron) at FLNR. The radiation yield of 225Ac was 550 Bq/(μA h mg 226Ra). 225Ac was isolated from the target material and radioactive impurities by the ion-exchange procedure. The 225Ac:227Ac:226Ra activity ratio in the preparation was 1:∼2 × 10-9:≤6 × 10-5. © Pleiades Publishing, Inc., 2006.
