Abstract
Radon gas is a radioactive element that appears in nature by the decay of radium found in terrestrial soils. This gas is able to travel between the pores of the ground and enter into the buildings where the concentration can increase and becoming a health risk to occupants from inhaling.
The World Health Organization rate the radon gas as a level 1 carcinogen agent. According to this organization, radon is the second leading cause of lung cancer contraction after tobacco.
Based on the perception of risk derived from epidemiological medical studies, some countries have established radon concentration values as safety limits, above which is recommended or required an architectural intervention to reduce levels.
From an architectural perspective, there have been studies of several radon protection techniques to reduce radon immission in buildings or to evacuate it, in order to reduce the radon levels below the safety limits.
This article develops some protection strategies that have been being used for these purposes, some of which have been tested in Spain thanks to a research project funded by the Nuclear Safety Council, and developed by the Eduardo Torroja Institute and the University of Cantabria.
