We are developping a low-cost instrument to measure the radon in CO2 samples collected in the massif central and other places.

We now have three prototypes: RADONTRON1, RADONTRON2, and RADONTRON3. The first two utilize RadonEye detectors, while the third employs the Radoff Sense sensor. Additionally, we have incorporated CO2 sensors (0-100% from Mikroe CO2 Click) to estimate the CO2/Rn ratio in the samples. RadonEye uses the ionisation chamber technics with pulse detector.
