Soil-Plant-Atmosphere Modeling in the Context of Releases of 14C as a Consequence of Nuclear Activities

Abstract

The need to address radiological impacts from radiocarbon released to the biosphere has been recognized for some time. In 2011, the Swedish Radiation Safety Authority (SSM) commissioned a study to develop a 14 C model of the soilplant-atmosphere system that would provide them with an independently developed assessment capability. This paper summarizes that study, which comprised a review of contemporary models, the development of a new conceptual model, SSPAM 14 C, and the application of SSPAM 14 C to a set of experimental data relating to the atmospheric exposure of cabbages. © 2013 by the Arizona Board of Regents on behalf of the University of Arizona.
