ስለ Technetium
Technetium is a silvery-gray radioactive metal. It was the first element produced artificially, by bombarding molybdenum with deuterons. Technetium-99m is the most widely used isotope in medical diagnostic imaging.
ፕሮግራሞች
Medical imaging (Tc-99m in SPECT scans), nuclear medicine diagnostics, and steel corrosion inhibitor.
ሐቅ
Technetium was the first artificially created element, and tiny traces have been found in nature from spontaneous uranium fission.
