What is a key advantage of using semiconductor detectors over traditional detectors?

A key advantage of using semiconductor detectors over traditional detectors, like gas-filled or scintillation detectors, is their higher sensitivity and resolution. Semiconductor detectors, typically made from materials such as silicon or germanium, have the capability to detect lower levels of radiation and to provide more precise energy measurements of the incoming radiation. This improved resolution stems from the small size of the detector and the high atomic number of the semiconductor material, which allows for a more efficient interaction with incoming photons or charged particles.

The increased sensitivity means that semiconductor detectors can identify weak radiation sources that might be overlooked by traditional detectors. Additionally, the finer energy resolution benefits applications such as spectroscopy, where the distinction between different isotopes or energy levels is crucial for accurate analysis and identification of materials.

While lower cost of production, larger physical size, and ease of use may be considerations for different types of detection technology, they do not represent the defining advantages of semiconductor detectors in the context of radiation detection performance. The superior sensitivity and resolution are what primarily elevate the utility of semiconductor detectors in various scientific and medical applications.
