摘要：

A radiochemical charged particle activation procedure for the simultaneous production of carrier-free radioisotopes of more than one element in a single target and their subsequent separation through LLX has been demonstrated. The carrier free isotopes, Nb-95,Nb-96, Tc-93,Tc-94,Tc-95,Tc-96,Tc-99m and Ru-94,Ru-95,Ru-97,Ru-103 formed through Mo(alpha,alpha pxn), Mo(alpha,pxn) and Mo(alpha,xn) nuclear reactions with 40 MeV alpha-particle as detected by nondestructive gamma-ray spectroscopy, have been effectively separated through LLX using TOA as an anionic extractant. Separation of the bulk matrix of molybdenum from the carrier free products has been monitored radiometrically using isotopic Mo-93,Mo-99m formed through the Mo(alpha,alpha xn) reaction, as radioindicators for the target element. Purity of the separated carrier free radionuclide has been verified by gamma-ray spectrometry.
