This publication contains radioisotope decay and production details of 49 isotopes that can be prepared using cyclotrons. The introductory chapter discusses the principles of radioisotope production using cyclotrons, while Chapter 2 contains data on nuclear decay characteristics such as half-life, mode of decay, energy and abundance, nuclear reactions and excitation functions of the selected isotopes. This publication will be of interest to scientists and engineers working in radioisotope production using cyclotrons.
