Which material is commonly used in Solid-State Crystal detectors?

Cadmium tungstate is a commonly used material in solid-state crystal detectors due to its favorable properties for detecting X-rays and gamma rays. The crystal structure of cadmium tungstate allows for the efficient conversion of incident radiation into a measurable signal, making it effective for use in various detection applications, including medical imaging and radiation monitoring. Its high atomic number and density contribute to better interaction with high-energy photons, improving the sensitivity and energy resolution of the detector.

In contrast, the other materials mentioned, such as silicon rubber and plastic composites, do not provide the structural support or the high interaction cross-section needed for efficient radiation detection. Lead glass, while historically used in some detection applications, does not match the performance characteristics of cadmium tungstate in terms of energy resolution and efficiency. As a result, cadmium tungstate stands out as the superior choice for solid-state crystal detectors in contexts requiring precision in radiation detection.
