Abstract

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,95,96Nb,93,94,95,96,99mTc and94,95,97,103Ru formed through Mo(α,αpxn), Mo(α,pxn) and Mo(α,xn) nuclear reactions with 40 MeV α-particle as detected by nondestructive γ-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 isotopic93,99mMo formed through the Mo(α,αxn) reaction, as radioindicators for the target element. Purity of the separated carrier free radionuclide has been verified by γ-ray spectrometry.
