Abstract

Summary Alpha particle activation of natural Bi2O3 results in the formation of astatine radionuclides. A simple and rapid separation method of astatine is presented from the bulk target matrix bismuth by employing liquid-liquid extraction (LLX) method using methylisobutylketone (MIBK) and hydrochloric acid. Back extraction of astatine was performed by ethylenediaminetetraacetic acid (EDTA) solution at pH 10.
