Some Medical Applications of Accelerators

The present uses of accelerators in nuclear medicine and radiation therapy are summarized. Attention is called to the widespread use of these devices for production of radioisotopes for diagnostic purposes and of x rays for treatment of cancer. Developments presently underway to make use of high energy heavy nuclear particles for both isotope production and therapy are discussed and an overview is presented of one of a new family of accelerators nearing completion. In view of the large fraction of the total population who stand to benefit from better diagnostic and therapy modalities, the question is posed whether more adequate resources should not be made available for improving diagnostic and therapeutic capabilities while minimizing radiation dose to the patient.
