What are the two types of Continuous RDP measurement devices?

The correct answer identifies the two types of Continuous Radon Decay Product (RDP) measurement devices: Scintillation Disk and Surface Barrier Detector. Continuous measurement devices are essential for providing real-time data on radon levels and their decay products in the environment, which is crucial for assessing potential health risks.

Scintillation Disk devices operate by utilizing scintillation materials that emit light when they interact with radiation, allowing for the detection of alpha particles from radon decay products. Surface Barrier Detectors, on the other hand, can effectively capture and measure alpha particles and are commonly used in continuous monitoring applications for their sensitivity and efficiency in detecting ionizing radiation.

Both devices are designed to facilitate ongoing monitoring and provide immediate feedback about radon exposure, which is vital in residential and occupational settings where radon levels may vary. Understanding their functionality helps technicians take precise measurements and ensure safety standards are met in radon mitigation efforts.
