Strontium iodide is an inorganic compound with the chemical formula {{chem2|SrI2|auto=1}}. It is a salt of strontium and iodine. It forms a hexahydrate {{chem2|SrI2*6H2O}}. It is an ionic, water-soluble, and deliquescent compound that can be used in medicine as a substitute for potassium iodide.{{Citation | last =Shoemaker | first =John V. | year =1908 | title =A Practical Treatise on Materia Medica and Therapeutics | edition =7th | location =Philadelphia | publisher =F.

It is also used as a scintillation gamma radiation detector, typically doped with europium, due to its optical clarity, relatively high density, high effective atomic number (Z=48), and high scintillation light yield.{{cite journal|last1=Prettyman|first1=Thomas|last2=Burger|first2=Arnold|last3=Yamashita|first3=Naoyuki|last4=Lambert|first4=James|last5=Stassun|first5=Keivan|last6=Raymond|first6=Carol|title=Ultra-bright scintillators for planetary gamma-ray spectroscopy|journal=SPIE Newsroom|year=2015|issn=1818-2259|doi=10.1117/2.1201510.006162}} In recent years, europium-doped strontium iodide ({{chem2|SrI2}}:{{chem2|Eu(2+)}}) has emerged as a promising scintillation material for gamma-ray spectroscopy with extremely high light yield and proportional response, exceeding that of the widely used high performance commercial scintillator {{chem2|LaBr3}}:{{chem2|Ce(3+)}}. Large diameter {{chem2|SrI2}} crystals can be grown reliably using vertical Bridgman technique {{Cite book|last1=Datta|first1=A.|last2=Lam|first2=S.|last3=Swider|first3=S.|last4=Motakef|first4=S.|title=2016 IEEE Nuclear Science Symposium, Medical Imaging Conference and Room-Temperature Semiconductor Detector Workshop (NSS/MIC/RTSD) |chapter=Crystal growth of large diameter strontium iodide scintillators using in Situ stoichiometry monitoring |date=October 2016|pages=1–4|doi=10.1109/NSSMIC.2016.8116640|isbn=978-1-5090-1642-6|s2cid=31775311}} and are being commercialized by several companies.{{Cite web|url=http://www.capesym.com/sri2.html|title=CapeSym {{!}} SrI₂(Eu)|last=Inc.|first=CapeSym|website=www.capesym.com|access-date=2018-02-13}}{{Cite web|url=http://rmdinc.com/strontium-iodide/|title=Strontium Iodide {{!}} RMD|website=rmdinc.com|language=en-US|access-date=2018-02-13|archive-date=2018-02-14|archive-url=https://web.archive.org/web/20180214051051/http://rmdinc.com/strontium-iodide/|url-status=dead}}
