Which of the following best describes Solid-State Crystal detectors?

Solid-State Crystal detectors are characterized by their high proton absorption and sensitivity to temperature. These detectors utilize materials that can effectively absorb incoming radiation, which is pivotal for their function. The materials used in solid-state detectors can respond differently to temperature variations, making their design and operation sensitive to environmental conditions. This sensitivity can impact the detector's performance and requires careful management in applications where consistent temperature control is crucial.

The other characteristics listed in the choices do not accurately reflect the primary features of solid-state crystal detectors. While they may be relatively lightweight compared to other types of detectors, the defining trait is their ability to absorb protons well and their temperature sensitivity, which plays a significant role in optimizing their use in various imaging and detection scenarios.
