What is the purpose of a radon measurement device?

The purpose of a radon measurement device is specifically to detect alpha particles, which are emitted during the radioactive decay of radon gas. Radon is a naturally occurring radioactive gas that can accumulate in homes and buildings, particularly in lower levels and basements, posing health risks such as lung cancer upon prolonged exposure.

Radon measurement devices work by identifying and measuring the concentration of radon in the air through the detection of the alpha particles that result from radon's decay. This allows for the assessment of potential radon-related health risks in particular environments, helping to identify areas that may need remediation or mitigation efforts to reduce radon levels and safeguard occupants' health.

The other options do not pertain to radon measurement. Air quality measurement encompasses a broader range of pollutants and is not specific to radon. Humidity testing measures moisture levels in the air, while temperature monitoring focuses on the thermodynamic state of the environment, neither of which relates directly to the detection of radon gas or its associated alpha particles.
