Separation of carrier free dysprosium and terbium isotopes from 12C6+ irradiated Nd2O3

Investigation on the production and isolation of 149,150,151Tb from 12C irradiated natural praseodymium target

“…The optimum separation conditions and the corresponding separation factors are presented in Table 3. The extraction patterns of nca and bulk lanthanides are quite confirmative with our earlier experiments for production and separation of nca lanthanides [10][11][12]. It is noteworthy to mention that due to finer adjustment of HDEHP strength, and addition of hydrazine sulfate in the second step of extraction, we obtained much improved Table 4.…”

“…In 1999, Lahiri et al produced nca 150−153 Dy and the daughter products 150−153 Tb using the 12 C and 16 O induced reactions on natural Nd 2 O 3 and CeO 2 targets respectively at 80 MeV incident energy. The nca Dy and Tb radionuclides were separated from the natural Nd target matrix by LLX using liquid cation exchanger di-(2-ethylhexyl)phosphoric acid (HDEHP) dissolved in cyclohexane as organic phase and HCl as aqueous phase [10,11]. The group also reported the production of nca 151,152 Tb radionuclides by 16 O induced reaction on lanthanum oxide at ∼ 78 MeV incident energy.…”

Across the energy scale: from eV to GeV

“…Series of rare earth radionuclides were produced thereafter by heavy ion activation [17][18][19][20][21][22][23][24][25][26][27][28][29]. Table 1 shows a summarized report on production and separation of NCA rare earth radionuclides by heavy ion activation.…”

Comparison on the production of radionuclides in 1.4 GeV proton irradiated LBE targets of different thickness

“…We found several terbium radionuclides (e.g., 151,153,154 Tb, listed on Table 2), therefore it is expected that a-emitting 149 Tb will also be produced in large quantities in proton irradiated LBE targets, which we could not observe because the radionuclide has no suitable c-energies. 157 Dy (T 1/2 = 8.14 h) is used as a scanning agent for bone and bone marrow [34,35], while 169 Lu (T 1/2 = 34.06 h) is the parent isotope of 169 Lu/ 169 Yb generator system. 169 Yb (T 1/2 = 32.02 days) is gaining interest in brachytherapy [36,37].…”
