Using an emissions barrier for controlling radon in indoor air
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 i
