How are Carbon Absorption Detectors (CADs) typically configured?

Carbon Absorption Detectors (CADs) are designed based on the principles of gamma-ray spectroscopy, which allows them to measure the concentrations of radon gas in a specific environment. This technique relies on detecting the gamma radiation emitted from radon and its decay products. By analyzing the emitted gamma rays, the CAD can calculate the level of radon present in the air.

The use of gamma-ray spectroscopy is crucial because it provides a reliable and sensitive means of detecting radioactivity. Other methods such as fluid displacement technology, nasal inhalation techniques, and thermal conductivity are not relevant to the functioning of CADs, as they do not involve the principles of radiation detection and measurement that gamma-ray spectroscopy employs for assessing radon levels. Understanding the operation of CADs in the context of gamma-ray spectroscopy is key for effective radon measurement and safety assessments in residential and commercial environments.
