What is the CZT Radiation Detector Market?

Cadmium Zinc Telluride (CZT) radiation detectors are semiconductor-based devices used for detecting X-rays and gamma rays. Unlike conventional scintillator detectors, CZT detectors directly convert radiation into electrical signals without requiring cooling systems.

CZT material possesses:

• High effective atomic number (~50)
• High density (5.81 g/cm³)
• Wide band gap (1.6 eV)
• Excellent energy resolution

These properties enable accurate detection and analysis of low-energy X-rays and gamma radiation, making CZT detectors ideal for medical diagnostics, nuclear safety monitoring, and security applications.

The ability to operate at room temperature while delivering high-resolution output gives CZT detectors a significant competitive advantage over traditional radiation detection technologies.
