We are developping a low-cost instrument to measure the radon in CO2 samples collected in the french Massif Central and other places in order to constrain the origin of Helium and CO2 in the carbogaseous springs. .
We now have four prototypes: RADONTRON1, RADONTRON2, RADONTRON3 and RADONTRON4. The first two utilize RadonEye detectors, while the two others employs the Radoff Sense sensor. Additionally, we have incorporated CO2 sensors (0-100% from Mikroe CO2 Click and Senseair S8-0053 sensor, 0-10 000ppm) to estimate the CO2/Rn ratio in the samples. These RADONTRONX are calibrated against the CALEN instrument hosted at BRGM.
