摘要
放射性同位素^(54)Mn是一种半衰期较长的单能γ辐射体,在农业、医学等诸多领域有着广泛的应用。而国内利用加速器制备^(54)Mn的工作还未见报道,为填补国内利用加速器制备^(54)Mn的研究空白,本工作在四川大学CS-30回旋加速器上开展了无载体^(54)Mn制备的相关研究。采用能量为11.5 MeV、束流强度为30μA的α粒子辐照天然金属钒靶,产生核反应^(51)V(α,n)^(54)Mn。再通过6 mol/L HNO_(3)溶解,Dowex-50×8阳离子交换树脂柱放化分离得到了活度约为252μCi的无载体^(54)Mn,放射性核纯度为99.9%,产额约为0.8μCi/μA·h。
Radionuclide^(54)Mn,as a gamma emitter with long half-life and single,high intensity gamma emission ray,has a wide application in many fields.However,so far,the preparation of^(54)Mn has not been seen in the domestic reports.To obtain radio-isotope^(54)Mn via an accelerator,the preparation of carrier-free^(54)Mn by CS-30 cyclotron was investigated in this work.A natural Vanadium target was used and irradiated by alpha beam with the energy of 11.5 MeV and the beam current of 30μA for 10.5 hours.The irradiated V target was dissolved in 6 M HNO_(3)and separated by Dowex-50×8 ion exchange resin.As a result,we obtained about 252μCi carrier-free ^(54)Mn with radionuclide purity of 99.9%and the yield was about 0.8μCi/μA·h.
