Among the fascinating new problems of medical research is how to use radioisotopes—forms of normally stable elements made radioactive in atom smashers. Radioisotopes have already become helpful in irradiating and arresting cancer. Lately, researchers have achieved even more significant results in cancer diagnosis. Because radioisotopes tend to concentrate in certain organs or diseased tissues, physicians have been able to detect tumors as much as six months before they appear on conventional X rays. Result: an important head start in the treatment of those that are malignant.
What makes radioisotopes so valuable is that...
