Production of Radionuclides for Tracers

Abstract

This chapters deals with production of radionuclides by both neutron bombardment from nuclear reactors and heavy charged accelerated atoms from accelerators. In the case of neutrons, most radionuclides have low specific activity due to the present carrier. The production of carrier‐free radionuclides is described.

“…In another unusual procedure, 123 I is produced by a beam of 25 MeV electrons in a 10-h irradiation of a tantalum target enriched with 124 Xe. About 200 mCi of 123 I accumulate through a photofission reaction, and this material can be used for medical purposes after appropriate extraction [42]. A powerful linear accelerator is capable of producing high-purity 123 I by the spallation process.…”
