DOI: 10.1016/j.jhazmat.2020.122344
Abstract: A common method to measure radon exhalation rates relies on the accumulation chamber technique. Usually, this approach only considers one-dimensional gas transport within the soil that neglects lateral diffusion. However, this lateral transport could reduce… read more here.
