Technetium-99m (99m Tc) is a metastable nuclear isomer of technetium-99 (itself an isotope of technetium) symbolized as 99m Tc that is used in tens of millions of medical diagnostic procedures annually making it the most commonly used medical radioisotope in the world.

Iodine-131 (131 I I-131) is an important radioisotope of iodine discovered by Glenn Seaborg and John Livingood in 1938 at the University of California Berkeley. It has a radioactive decay half-life of about eight days. It is associated with nuclear energy medical …

Gadolinium is a chemical element with the symbol Gd and atomic number 64. Gadolinium is a silvery-white metal when oxidation is removed. It is only slightly malleable and is a ductile rare-earth element.Gadolinium reacts with atmospheric oxygen or moisture slowly to form a black coating. Gadolinium below its Curie point of 20 °C (68 °F) is ferromagnetic with an attraction to a magnetic …

Indium-111 (111 In) is a radioactive isotope of indium (In). It decays by electron capture to stable cadmium-111 with a half-life of 2.8 days. Indium-111 chloride (111 InCl) solution is produced by proton irradiation of a cadmium target (112 Cd(p 2n) or 111 Cd(p n)) in a cyclotron as recommended by International Atomic Energy Agency (IAEA).The former method is more commonly used as it results …

Rubidium-87 has a half-life of 48.8 × 10 9 years which is more than three times the age of the universe of (13.799 ± 0.021) × 10 9 years making it a primordial nuclide . It readily substitutes for potas…
