Indoor radon in a glass building.

ABSTRACT

Measurement of radon was carried out on seven different floors of a 32-storey glass-faced building. It revealed the presence of relatively comparable amounts of radon on every one of the floors investigated; however, the concentrations (4.00-14.53 Bq/m3) did not exceed the safety threshold. Based on the result of a previous investigation showing significant concentrations of radon in concrete buildings, it is imputed from the finding of the present study that the type of glass used as a building material in this case was unlikely to be an additional source of radon.
