Theoretical Prediction of the Preferred Production Routes of 225Ac from Proton Induced Reactions on 232Th

Emmanuel C. Hemba, Olumide O. Ige, Haruna Ali & Sunday A. Jonah · Journal of Scientific Research and Reports · 2020

Alpha emitting radionuclides have potential for the therapy of cancers because of their high linear energy transfer, and short range biologic effectiveness. Alpha emitter 225Ac(T1/2 = 10.0 days) is a potent nuclide for targeted radionuclide therapy. 225Ac excitation functions via...
