Technetium -99m is a widely used radioactive tracer isotope in Nuclear Medicine.It's gamma ray energy of about 140 keV is convenient for detection. The fact that both its physical half-life and its biological half-life are very short leads to very fast clearing from the body after an imaging process.echnetium -99m is a widely used radioactive tracer isotope in Nuclear Medicine.
