The primary measures against radon in buildings are a tight contact structure or venting the subsoil beneath the building. In many cases, ventilation systems used in buildings to ensure good indoor air quality can also be used to reduce the radon con

The underground air ducts along peripheral walls of a building are a remediation method, which principle is to enable an air flow along the moist building structure’s surface to allow a sufficient evaporation of moisture from the structure. This me

This article focuses on an experimental study of the influence of imperfections on the value of the radon diffusion coefficient of various waterproofing materials. Microscopic holes were made by a thin tip or by a microdrill bit to imitate the real d

Gas radon is the main source of ionising radiation for humans and the second cause of lung cancer, just after smoking. Radon is present in the ground, and its concentration differs soil by soil according to the permeability and the mineral compositio

New definitions of the radon resistance and radon transmittance of waterproofing materials are introduced. They are based on the real steady-state radon distribution within the materials. Both quantities can therefore be considered as suitable parame
