Ecosys-87 : a dynamic model for assessing radiological consequences of nuclear accidents

摘要: The time-dependent radioecological simulation model ECOSYS-87 has been developed to assess the radiological consequences of short-term depositions radionuclides. Internal exposure via inhalation and ingestion, as well external from passing cloud radioactivity deposited on ground, are included in model. site-specific parameter values representative Southern German agricultural conditions; however, design facilitates adaption other situations. ingestion dose is calculated a function time considering 18 plant species, 11 animal food products, processed products. estimated for six age groups using age-dependent consumption rates factors. Results demonstrate pronounced influence regarding year (season) deposition relative importance pathways. Model results compare with activities foods measured after Chernobyl accident.
