Using an emissions barrier for controlling radon in indoor air

Mattsson, Johan ; Lehtimaa, Timo and Larsson, Lennart LU (2022) 17th International Conference on Indoor Air Quality and Climate, INDOOR AIR 2022
Abstract

An emissions barrier consisting of a cloth with a hydrophilic polymer layer and an adsorbent layer was found to be efficient in stopping radon emissions from radium-containing aerated concrete. Laboratory studies revealed a radon permeability of k= 3.958 x 10-11 m2/s. Applying the cloth indoors in an apartment, on the floor and three walls made up from aerated concrete, resulted in a decrease in indoor air concentrations from 240 to 120 Bq/m3. We conclude that an adsorbent-containing emissions barrier may be useful for controlling radon in buildings containing aerated concrete.
