Soil condition systematic investigations

The second approach is to investigate both experimentally and theoretically the influence of soils at a localized level, on the scale of an individual house, for example. Production and transport of radon in soils and migration of radon into houses depend upon local soil conditions, and results of these studies will improve our basic understanding of the physical processes involved. This in turn will aid in the systematic development of more effective entry identification and mitigation techniques to prevent or reduce radon entry into dwellings. 

In order to avoid the difficulties of naturally occurring variations in study conditions, Fall et al. (1988) studied the emission of sulfur gases from several plant/soil systems using a flux chamber. The study was designed so that emissions from soil could be separated from emissions from plants. Variable amounts of carbon disulfide were emitted from wheat. The effects of light and temperature were observed. Further work was proposed so that systematic investigation could accurately measure the contributions of a number of sulfur compounds under varying conditions.
