A Radon detector prototype developed by the Novara Observatory team (De Antoni et al., 2011) was installed at the Fermo Station in January 2020. The installation followed the indications of the Novara Observatory team, which suggested to bury the pipe vertically with the bottom end open, and with the tube cap protruding a few cm from the ground. The scheme of the placement of the tube with a photo of the open cap is shown in Figure 1, note the bag that protects the sensor from condensation and the thermal insulating coating to reduce convective motions inside the pipe.
