Measurement devices for radon are primarily categorized into devices that measure radon gas and those that measure radon decay products. Radon gas itself is a colorless, odorless radioactive gas that can accumulate in homes and buildings, posing health risks due to its radioactivity. The primary concern is the direct measurement of radon gas levels in the environment because high concentrations can lead to increased radiation exposure and health issues, particularly lung cancer.

Additionally, measuring radon decay products, which are the byproducts formed when radon gas decays, is crucial as they can also contribute to radiation exposure. These decay products attach to airborne particles that can be inhaled, thereby increasing the risk of radiation exposure to lung tissue.

Devices specifically designed to measure these parameters are essential for conducting accurate assessments of radon levels in residential and commercial properties, which is vital for mitigating health risks associated with radon exposure. Other types of devices mentioned in the context of the other options focus on environmental conditions or different types of measurements that are not directly relevant to radon's influence or detection.
