Abstract: | Radon concentration in soil gas can be employed to trace the presence of gasoline contamination because it is very soluble in hydrocarbons. Radon available in the soil pores accumulates in the contaminated volume, producing a local deficit at shallow depth that can be easily mapped. The suitability of this method is here checked by field simulation of a gasoline spill and by laboratory experiments where known amounts of a volcanic tuff contaminated with increasing gasoline show proportional drops of radon exhalation rates. |
