Abstract

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.

确定由土壤污染引起的室内粉尘污染程度的初步研究

为了制定更现实的风险评估，进行了一项实验计划，以表征室内，住宅环境以及室内环境与室外环境污染物之间的关系。测量的参数包括土壤中铀的浓度，室内表面灰尘的质量负荷，以及室内灰尘中铀的浓度。室内灰尘样本收集使用个人空气采样器改装为低流量真空吸尘器。室内粉尘中的铀浓度采用动态磷光分析测量，室外土壤中的铀浓度采用伽马射线能谱法分析钍- 234活度。这项初步研究估计有20%至30%的室内污染来自土壤污染源。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
