Radon
Introduction
Radon is an element that occurs in a radioactive decay chain that starts with the decay of
Uranium to Thorium and ends with a stable isotope of lood. Uranium and with that
Radon is present in low concentrations in nature and with that one also encounters it in
building materials.
Since Radon is a gas at room temperature, it is continually escaping from these building
materials. At well-ventilated locations this is of little relevance but in at locations where
ventilation is insufficient this may lead to relatively high concentrations of Radon.
Generally concentrations of Radon are expressed in [Bq.m-3]. The WHO (World Health
Organization) recommends to maintain levels below the 200 [Bq.m-3].
