Overview and new advances of RADSIM, a research project for the generation and validation of numerical models for the prediction of radon entry into buildings based on a characterization of the terrain and a typological definition of construction in Spain.

This presentation will address the progress of the RADSIM project whose purpose is to study the feasibility of numerical modelling to predict the entry of radon into buildings and its accumulation inside from a detailed characterization of the terrain and a typological definition of the building
