Radioisotopes in Medicine

Published at the height of the atomic age, this book captures a remarkable moment in medical history when scientists first learned to harness radioactivity not as a weapon but as a healing force. Phelan traces the extraordinary journey from the discovery of radiation to its transformation into precise diagnostic tools and life-saving therapies. He explains the science accessibly: how isotopes like iodine-131 concentrate in specific organs, allowing physicians to visualize disease from within, and how cobalt-60 could be directed at tumors with unprecedented precision. The book documents case studies that must have seemed like miracles to contemporary readers: cancer patients whose tumors shrank, brain scans that revealed what X-rays could not, thyroid conditions diagnosed and treated with a single element. Written for a generation that had witnessed Hiroshima but also the promise of Atoms for Peace, this volume represents the optimistic faith that nuclear science would conquer disease. It remains a valuable snapshot of medicine on the cusp of transformation, before CT scans and MRI machines, when radioactive tracers were among the most sophisticated technology in a physician's arsenal.
