Indium (49 In) consists of two primordial nuclides, with the most common (~ 95.7%) nuclide (115 In) being measurably though weakly radioactive. Its spin-forbidden decay has a half-life of 4.41×10 14 years, much longer than the currently accepted age of the Universe.
Radioactive isotopes are used in medicine for both treatment and diagnostic scans. The most common isotope used in diagnostic scans is Technetium-99m, used in approximately 85% of all nuclear medicine diagnostic scans worldwide. It is used for diagnoses involving a large range of body parts and diseases such as cancers and neurological problems ...
Isotope separation is the process of concentrating specific isotopes of a chemical element by removing other isotopes. The use of the nuclides produced is varied. The largest variety is used in research (e.g. in chemistry where atoms of "marker" nuclide are used to figure out reaction mechanisms).
Naturally occurring lanthanum (57 La) is composed of one stable (139 La) and one radioactive (138 La) isotope, with the stable isotope, 139 La, being the most abundant (99.91% natural abundance). There are 39 radioisotopes that have been characterized, with the most stable being 138 La, with a half-life of 1.03×10 11 years; 137 La, with a half ...
WSMV-TV (channel 4) is a television station in Nashville, Tennessee, United States, affiliated with NBC. It is owned by Gray Media alongside low-power Telemundo affiliate WTNX-LD (channel 29). The two stations share studios on Knob Road in west Nashville, where WSMV-TV's transmitter is also located.
