Abstract We studied the simple separation of radiosilvers from proton- or deuteron-irradiated natural palladium (natPd) targets, and successfully separated radiorhodium, radiosilver and radiopalladium using an anion-exchange resin. The yields of radiosilvers were 105Ag: 1.0 ± 0.32 MBq/μAh; 106mAg: 2.0 ± 0.64 MBq/μAh; 110mAg: 0.019 ± 0.0063 MBq/μAh (n = 4) at the end of bombardment with a total recovery rate of 98 % under the following irradiation conditions (deuteron beam energy: 20 MeV; beam current: 10 μA; irradiation time: 2.25 ± 0.50 h). We also evaluated the recycling of the palladium target.

从回旋加速器辐照的钯靶中分离放射性银

摘要 我们研究了从质子或氘辐射的天然钯 (natPd) 靶中简单分离放射性银的方法,并使用阴离子交换树脂成功地分离了放射性铑、放射性银和放射性钯。放射性银的产量为 105Ag:1.0 ± 0.32 MBq/μAh;106mAg:2.0 ± 0.64 MBq/μAh;110mAg: 0.019 ± 0.0063 MBq/μAh (n = 4) 在以下辐照条件下(氘核束能量:20 MeV;束流:10 μA;辐照时间:2.25 ± 0.50 小时)。我们还评估了钯靶的回收利用。
