RECOMMENDATIONS FOR THE SETTING UP OF A RADON IN SOIL NETWORK-BASED UPON A DECENNIAL STUDY

A radon in soil survey has been conducted in Mexico for 10 years, usin g Solid State Nuclear Tracks Detectors with monthly sampling. The prel iminary data analysis shows that a minimum of 20 months is required to attain a significant knowledge of the average radon content and varia tions. No clear periodicity of the data appears, nor any direct influe nce of the atmospherical parameters. Recommendations are drawn from th is survey depending on the finality of the contemplated experiments us ing SSNTD for monitoring radon in the ground.
