Radiological Impact Assessment of Acute Tritium Releases in Environment—A Soil Dynamic Model

Radiological and environmental impact assessment models are important tools that support nuclear safety. The present study summarizes the upgrades of a research-grade model (CROPTRIT) with an emphasis on a soil submodel and the balance between air-to-plant and soil-to-plant pathways, together with the needs that must be accomplished by an operational model in order to be applied to nuclear facilities involving large tritium loads.
