Strontium iodide is used as a scintillation gamma radiation detector, in a range of hand-held radiation detection instruments and in medical, industrial and environmental applications. Strontium iodide is also used in a variety of iodine-containing medicines as an alternative to potassium iodide.

Iodine is an important organic molecule in many fields including biology, chemistry and medicine. In the laboratory it is used to make various types of iodine-containing compounds such as iodine-labeled radiotracers, dyes, pigments and radiolytic enzymes.


Inhalation of strontium iodide may cause headache, tight chest, irritation of the nose and respiratory system, lacrimation and burns to the mouth. Ingestion may lead to gastric irritation, abdominal pain and diarrhea.


Iodide is a strong irritant to the skin and can cause redness, black and blue spots, boils, pimples, hives and blisters. In severe cases, it can cause chemical burns to the eyes and a severe rash.


Work with strontium iodide should be conducted in an area free of water and moisture. Wear appropriate protective clothing and gloves when working with the material.

The Strontium Iodide Radiation Instrument (SIRI) is a space-qualified scintillation detector using europium-doped strontium iodide and silicon photomultiplier (SiPM) readout technology, covering the energy range from.04 to 8 MeV. SIRI is currently in space and has been collecting data since December 2018.
