Context
New regulations on Radon are more and more implemented wordwide, such as Council Directive 2013/59/EURATOM of December 5, 2013 which introduced national legislations in Europe. Therefore, national actions are progressing significantly, as well as the need for Radon mitigation.
Among the many mitigation actions to take, there is the reduction of Radon entry into a building by improving the tightness of the parts of the structure which are in contact with the soil. This can be done, for example, by sealing the base plate of the building with a Radon-tight foil.
To test the foil for Radon gas-tightness, its permeability has to be carefully and precisely evaluated with a high performance device, such as the professional Radon monitor AlphaGUARD of Bertin Instruments.
