摘要

The paper discusses the measurement of soil permeability and pressure fieldsusing EPA's soil-gas chamber, designed to study the production and transport of radon and other potential indoor air pollutants originating in soils. The chamber is instrumented to measure distributions of radon and pressure fields and also moisture distributions and their resulting influence on soil permeability. An analytic solution for advective flow in the soil-gas chamber is presented which includes the effects of moisture-dependent spatial variations of the permeability. Measurements of the pressure field are compared with model calculations. Relatively good agreement between the measurements and calculations is obtained, except near the water level where boundary conditions are not rigorously satisfied.
