A europium-doped, calcium-fluoride scintillator system for low-level tritium detection

NRC Job Code V6060: Extended in-situ and real time monitoring. Task 4: Detection and monitoring of leaks at nuclear power plants external to structures

“…It is also vulnerable to fouling and subject to memory effects from tritium retention on the solid scintillant. These problems are partially overcome by using inorganic scintillators with low water solubility such as europium-doped calcium-fluoride (CaF 2 [Eu]) 12 . Potentially, this type of solid scintillators may be developed into real-time applications.…”

Effects of sintering additives on preparation of CaF2 transparent ceramics

“…As a traditional optical material, calcium fl uorite plays an important role in industrial application and scientific research [1][2][3][4][5] , and is well known to be the best overall-performance optical material with many excellent properties as follows: wide transparence range(0.125 μm -10 μm); low index of refraction; high damage threshold; moisture resistance and chemical corrosion resistance; low melting point(1380 ℃), etc [6,7] . Thanks to these properties, calcium fluorite is appropriately used as window materials with a wave length ranging from ultraviolet (UV) to infrared ray (IR), widely applied in the fields such as ultraviolet lithography, astronomical observation, aerial survey, detection, high-resolution optical instruments and matrix materials of laser medium, etc [8][9][10][11][12][13][14][15] .…”

New limits on spin-dependent coupled WIMPs and on 2β processes in 40Ca and 46Ca by using low radioactive CaF2(Eu) crystal scintillators

“…Suitable detectors for 2β decay studies are the well-known calcium uoride scintillators [11,12]. In fact, they have a relatively large light output ( 60 % of NaI(Tl)) and offer excellent operational characteristics (nonhygroscopicity, inertness, insolubility, good mechanical properties, etc.)…”
