Technetium (Tc) is a synthetic transition metal with no stable isotopes, produced artificially through nuclear fission or cyclotron bombardment. It is primarily used in medical imaging and nuclear medicine applications, where its radioactive isotopes (especially Tc-99m) serve as tracers for diagnostic procedures including bone scans, cardiac imaging, and infection detection. Engineers encounter technetium primarily in nuclear medicine instrumentation design, radiation shielding, and specialized catalyst applications in chemical processing, where its unique nuclear and chemical properties offer advantages unavailable from stable elements.
