Индий ( 49 In) состоит из двух первичных нуклидов , причем наиболее распространенный (~ 95,7%) нуклид ( 115 In) является измеримым, хотя и слаборадиоактивным. Его запрещенный по спину распад имеет период полураспада 4,41 × 10 14 лет.
Стабильный изотоп 113 In составляет всего 4,3% природного индия. Среди элементов с известным стабильным изотопом только теллур и рений сходным образом встречаются со стабильным изотопом в меньшем количестве, чем долгоживущий радиоактивный изотоп. За исключением 115 In, наиболее долгоживущим радиоизотопом является 111 In с периодом полураспада 2,8047 дня. Все остальные радиоизотопы имеют период полураспада менее суток. Этот элемент также имеет 47 изомеров , самый долгоживущий - 114m1 In, с периодом полураспада 49,51 дня. Все другие метасостояния имеют период полураспада менее суток, в большинстве случаев менее часа, а многие измеряются в миллисекундах или меньше.
Indium-111 is used medically in nuclear imaging, as a radiotracer nuclide tag for gamma camera localization of protein radiopharmaceuticals, such as In-111-labeled octreotide, which binds to receptors on certain endocrine tumors (Octreoscan).[2] Indium-111 is also used in indium white blood cell scans, which use nuclear medical techniques to search for hidden infections.
