SOFTWARE TOOL FOR ASSESSMENT OF FOOD CONTAMINATION AND FOOD BANS REGULATIONS

摘要

Dynamic food chain model INGMODEL of radioactivity transport inside a human body is briefly described. Proposed methodology and corresponding user-friendly software enable estimating the consequences arising from ingestion of contaminated foodstuffs. The model is connected with interactive subsystems for entering of input data and graphical presentation of results. An effectiveness of some protective actions introduced in the ingestion pathway on population protection can be tested. The areas contaminated above the permissible limits can be presented directly on the map backgrounds and immediately used for decisions related to launching of the food bans regulations. Simulation of time and space evolution of committed doses from ingestion pathway enables estimate the risk for persons living for a long time in the polluted areas. Architecture of the INGMODEL subsystem was designed with the intention to facilitate examinations of influence of variability of input data. The sensitivity analysis and worst-case assessment can be accomplished as well. An example related to the variability of soil-plant transfer factors is given in the conclusion.
