isotopes for a number of special applications. The radioisotopes are produced by bombarding appropriate elements with neutrons in the reactor. Alternatively, radioisotopes can be produced by bombarding appropriate elements with various sub-atomic particles in a particle accelerator. MEDICAL APPLICATIONS Radioisotopes are used in medicine for both diagnosis and therapy. In diagnosis, the principle use is to locate abnormal tissue such as tumours. In therapy, radioisotopes are used to destroy abnormal cells within the body. Diagnosis
