In the present paper the interference of high CO2 concentration in soil radon flux measurement using a solid state silicon detector is discussed. A possible correction, making use of a chemical trap consisting of soda lime pellets, is successfully experimented at Cava dei Selci site (Roma, Italy). The interference is likely due to neutralization processes of 218Po ions in the CO2 dominant atmosphere occurring in the chamber of radon monitor and resulting in a reduced efficiency in electrostatic collection on the surface of the solid state detector
