NaI(Tl) or sodium iodide doped with thallium: NaI(Tl) is by far the most widely used scintillator material. It is available in single crystal form or the more rugged polycrystalline form (used in high ...

The others will follow over the next few years in Spain, Australia and, again, Gran Sasso. All will use sodium iodide crystals to detect dark matter, which no full-scale experiment apart from DAMA’s ...

The report describes the essential components of the experimental setup. This includes ultra-pure sodium iodide crystals enclosed in custom-made copper vessels. These are placed inside a detector ...

Both DAMA and COSINE search for dark matter particles slamming into atomic nuclei in crystals of sodium iodide. If a collision occurs, it should produce a tiny flash of light in the crystal.

THE scintillation spectrometer 1 using a sodium iodide crystal (thallium-activated) identifies the incident gamma-ray energy with the response to the photo-electric, Compton and (when ...

sells an $8,000 handheld detector, called the SAM 935, that uses a sodium iodide crystal and powerful software that can identify 90 isotopes in one second. Berkeley's chief rival, SAIC Corp. in ...
