What type of continuous radon monitor contains a chip attached to a power supply?

The correct answer is solid state silicon detectors. This type of continuous radon monitor utilizes a silicon-based chip that is integrated with a power supply. The chip detects alpha particles emitted by radon decay, allowing for real-time measurement of radon levels in the environment. The integration with a power supply enables continuous operation and the ability to provide timely data.

In contrast, other types of detectors operate using different principles. Gas chamber detectors utilize a gas-filled chamber to detect radiation, while electret ion chambers rely on the ionization produced by radon decay in a small volume of air. Activated charcoal detectors use charcoal to capture radon over a period but do not incorporate a power supply or a chip for real-time analysis. Understanding these differences is essential for recognizing the unique characteristics and applications of each type of radon measurement technology.
