摘要
Radon, an environmental pollutant gas, occurs naturally in soil. Although loess, an essential building material in northwest China, is commonly used, research on radon emissions from loess remains limited. This study aims to address this gap by conducting both field and laboratory experiments to examine the impact of water content on radon emission from loess. The findings reveal that the radon emission rate from loess follows a non-linear pattern with respect to water content, initially increasing and then decreasing. The highest cumulative radon concentration occurs at 14% moisture content, with an emission rate of 0.44 Bq·m-3/g·h. Moreover, high water content significantly inhibits radon emission from loess. These results have practical implications for ensuring "radon safety" in loess buildings.
