Most nuclear procedures are of a diagnostic nature. In some instances, however, radionuclides administered to the patient are valuable therapeutic tools. For example, one in every three persons admitted to U.S. hospitals undergoes a nuclear medical procedure for diagnosis or therapy. Many of these procedures employ radioisotopes. Some of the more frequent uses of medical radioisotopes include diagnosis and treatment of several major diseases, sterilisation of medical products such as tissue grafts, nutrition research, and biomedical research into cellular processes.

For medical purposes, an enormous collection of techniques is accumulated regarding production of short-Kved nuclides mainly by cyclotrons. The technique should undoubtedly be usefiil for appKcation of radioactive tracers to other fields. Such nucKdes include F, and also many nucKdes of metals, halogens, and rare gases. Reactor and cyclotron production of medical radioisotopes is described in Chaps. 38 and 39 of VoL 4, respectively. Basic data for production of short-Kved nucKdes by cyclotron were compfled with substantial references by Qaim (1982). Another review by Waters and Silvester (1982) emphasizes cyclotron-produced nuclides useful for inorganic studies with many references, too. 

Most of the irradiations for medical radioisotope production at cyclotrons are done using extracted beams. There is more versatility in working with the extracted beam than with the internal beam. Through controlled defocusing and wobbling, it is possible to decrease the...
