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.
