Editing Indium (section)

===Medical applications===
Radioactive indium-111 (in very small amounts) is used in [[nuclear medicine]] tests, as a [[radiotracer]] to follow the movement of labeled proteins and [[indium leukocyte imaging|white blood cells]] to diagnose different types of infection.<ref name="Indium-111 Radiochemical Indium Chloride Solution">{{cite web|title=IN-111 FACT SHEET|url=http://www.nordion.com/documents/products/In-111_Can.pdf|publisher=Nordion(Canada), Inc.|access-date=23 September 2012|archive-url=https://web.archive.org/web/20111203082605/http://www.nordion.com/documents/products/In-111_Can.pdf|archive-date=3 December 2011}}</ref><ref>{{cite journal |last1=Van Nostrand |first1=D. |last2=Abreu |first2=S.
