In the last decade, radon monitoring advanced with active techniques and a regional highfrequency network. The Italian Radon mOnitoring Network (IRON) started in 2010, growing from 19 to 136 stations. To handle the increasing data, a MySQL database was implemented in 2016, followed by advanced tools in 2019. This included a refined database, SQL procedures for automatic creation (preferring PostgreSQL), and MATLAB® procedures for data standardization. In this paper, the database’ structure and the procedures are described.
