Pilot study to determine levels of contamination in indoor dust resulting from contamination of soils
In order to develop more realistic risk assessments, an experimental program was conducted to characterize indoor, residential environments and the relationship between the indoor environment and contaminants that originated from the outdoor environment. Parameters measured included concentration of uranium in soils, mass loading of dust on indoor surfaces, and concentrations of uranium in indoor dust. Samples of indoor dust were collected using a personal air sampler modified to act as a low flow rate vacuum cleaner. The concentrations of uranium in indoor dust were measured using kinetic phosphorescence analysis, while the concentrations of uranium in outdoor soil were measured by analyzing the thorium‐234 activity using gamma‐ray spectrometry. This pilot study derived an estimate of 20 to 30% of indoor contamination resulting from sources in soil.
