Technetium-99m Market Size 2021 Global Trends and Top Key Players Update, Industry Expected to Register a High Growth in Share with CAGR of almost 3.29. Technetium 99m is used in majority of nuclear medicine imaging procedures. The 99 is the mass number, a total of 99 nucleons, and the m means it is in a metastable state before decaying to Technetium 99. Technetium 99m is one of the most commonly used radionuclides because its gamma ray has an energy of a 140keV Le technetium 99 a ete introduit dans la biosphere par les retombees atmospheriques consecutives aux explosions nucleaires et sa concentration dans l'environnement augmente regulierement du fait des operations liees au cycle des combustibles nucleaires. Sa presence chez certaines especes marines et son accumulation observee au niveau de la peau.
