· CsBr

Cesium bromide (CsBr) is an ionic ceramic compound belonging to the halide family, characterized by a face-centered cubic crystal structure and high optical transparency across a wide spectral range. It is primarily used in infrared optics and radiation detection applications where its transparency to infrared wavelengths and scintillation properties are exploited; CsBr is particularly valued for gamma-ray and X-ray detection in medical imaging, nuclear spectroscopy, and security screening systems. Compared to alternatives like NaI or CsI scintillators, CsBr offers faster decay times and good energy resolution, though it requires careful handling due to hygroscopic nature and is less commonly used than some competing materials, making it a specialized choice for performance-critical detection systems.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
