What type of radon measurement device does not provide hourly records of concentration?

The device that does not provide hourly records of radon concentration is the electronic integrating device. Unlike continuous radon monitors, which track and record radon levels in real-time throughout the day, electronic integrating devices are designed to capture and summarize data over a longer time frame, often providing an average concentration over a specific measurement period rather than detailed hourly records.

Continuous radon monitors continuously collect data, allowing for the monitoring of fluctuations in radon levels, while passive radon detectors and radon test kits also operate differently. Passive detectors accumulate radon over a certain exposure period (typically days to months) and then must be analyzed in a lab, and while they capture radon information, they do not provide hourly readings either. The electronic integrating device is specifically built for averaging, which is why it does not report hourly concentration values.
