Tc-99m (Technetium-99m)

Technetium-99m (Tc-99m) is a widely used radioactive isotope in medical imaging. It emits gamma rays, which can be detected by specialized cameras to create detailed images of organs and tissues inside the body. Because it has a short half-life of about 6 hours, it minimizes radiation exposure while providing clear diagnostic information. Tc-99m is produced from molybdenum-99 in hospitals or laboratories and is commonly used in procedures like bone scans, heart testing, and cancer detection. Its effectiveness and safety make it a vital tool in modern nuclear medicine for diagnosing various health conditions.
