Technetium-99m (Tc-99m) is a radioisotope of technetium that is widely used in medical imaging and diagnostic procedures. It is particularly valuable in nuclear medicine due to its favorable characteristics: 1. **Half-Life**: Tc-99m has a relatively short half-life of about 6 hours, which is ideal for medical applications as it minimizes radiation exposure to patients while allowing sufficient time for imaging procedures.
