Solid-state radiation detectors

Definition

Solid-state radiation detectors are devices that use semiconductor materials to detect ionizing radiation. They convert incoming radiation into electrical signals, which can then be measured and analyzed.

5 Must Know Facts For Your Next Test

1. Solid-state detectors typically use materials like silicon or germanium as the semiconductor.
2. These detectors offer high resolution and efficiency in detecting various types of radiation, including alpha, beta, and gamma rays.
3. When radiation interacts with the semiconductor material, it generates electron-hole pairs that are collected to produce an electrical signal.
4. Solid-state detectors are commonly used in applications ranging from medical imaging to nuclear physics research due to their precision and reliability.
5. Energy resolution is one of the key advantages, allowing for accurate identification of different radiation sources.
