Both laboratory and field observations have clearly demonstrated that accidentically released HT is converted to tritiated water by contact with bioactive soil. The HT conversion is characterized by the deposition velocity, vd. It was measured in the laboratory after the injection of HT into a closed gas circuit exposing the soil surface to the gas phase. Mainly the agricultural use of the soil governs vd. Forest soil has the highest and during the whole year almost constant HT/HTO conversion (about 10/sup -3/ m s/sup -1/). vd of field soil is more sensitive to its actual water content and has a distinct annual course. The laboratory results were confirmed in two HT- release experiments under field conditions in France and Canada. The reaction product HTO is reemitted from the soil back into the atmosphere in the range of some percent per hour.
