Which three components are essential for constructing a semiconductor radiation detector?

The components essential for constructing a semiconductor radiation detector include a semiconductor crystal, an amplifier, and a display screen.

The semiconductor crystal serves as the primary sensor where the interaction between ionizing radiation and the semiconductor material occurs. When radiation passes through the crystal, it creates electron-hole pairs, which are essential for signal generation.

Next, the amplifier is crucial because it boosts the small electrical signals produced by the semiconductor crystal into a more usable form. Without amplification, the signals might be too weak for further processing or analysis.

Finally, the display screen provides a visual representation of the detected radiation. It allows users to interpret the data generated by the detector, making it possible to assess radiation levels effectively.

The other choices involve components that, while they may be relevant in specific contexts, do not reflect the fundamental requirements of a basic semiconductor radiation detector. For instance, a photoconductor and shielding might be elements found in other types of detectors, but they are not core components of a semiconductor detector. Similarly, options featuring terms like electron-emissive crystal or detector housing refer to different technologies or physical structures that do not embody the essential functions provided by semiconductor detectors.
