Who is regarded as the father of nuclear medicine?

• A. George de Hevesy
• B. Ernest Lawrence
• C. Enrico Fermi
• D. Hal Anger

Answer: (A)

The field of nuclear medicine begins with using radioactive substances as tracers to study how the body handles compounds. George de Hevesy introduced the idea of labeling chemicals with radioactive isotopes and tracking their distribution in living organisms, showing that we can observe metabolism and physiology through imaging and measurement. This tracer approach is what underpins all nuclear medicine techniques, from diagnostic scans to targeted radiotherapies. The other figures contributed important related advances—Ernest Lawrence with the cyclotron to produce radionuclides, Enrico Fermi with foundational nuclear physics, and Hal Anger with the gamma camera that made clinical imaging of radiotracers practical—but the person widely regarded as the father of nuclear medicine is George de Hevesy.
