Acciones de rehabilitación frente a la entrada de gas radón

radon gas is a pathological agent for inhabitants of buildings where it is present. due to its origin in uranium decay chain, it bears radioactive effects that inside human body lead to higher risks of developing lung cancer. it comes from soils containing granite masses or other substrates containing uranium. it enters through common material used in constructions, such as concrete ground slabs, basement walls, etc. in order to avoid such gas immission into inhabited rooms, several measurements cab be considered for existing buildings. this study intends to show the results obtained for radon reductions by means of different constructive solutions, already designed and executed so as to stop radon gas immission into a prototype building constructed for this specific purpose.
