Progress Report for the Production of Medical Radioisotopes at Korea Institute of Radiological and Medical Sciences (KIRAMS)

摘要

Korea Institute of Radiological and Medical Sciences (KIRAMS) has a great potential for the production of interesting radionuclides of positron emitters for PET images and gamma ray emitters for SPECT via various (p,xn) reactions. Several different targets have been used for producing specific radionuclides: gas targets employed for C-11, F-18 and 1-123 production (Nordion), a liquid target used only for the F-18 production, and two solid targets (IB A) prepared for the production of Ga-67 and Tl-201 radionuclides. The production of five radionuclides (C-11, F-18, 1-123, Ga-67, Tl-203) is carried at KIRAMS with enriched target materials. The average yields of F-18, 1-123, Ga-67, and Tl-201 radionuclides are 90 mCi/muAh, 10 mCi/muAh, 3 mCi/muAh, and 3 mCi/muAh at the end of beam (EOB), respectively. The radiochemical purities of products have been achieved higher than 99.7 %.
