| 内容記述 | A Code MOGRA (Migration Of GRound Additions) is a migration prediction code for toxic ground additions including radioactive materials in a terrestrial environment, which consists of computational codes that are applicable to various evaluation target systems, and can be used on personal computers. The computational code has the dynamic compartment analysis block at its core, the graphical user interface (GUI) for model formation, computation parameter settings, and results displays. The compartments are obtained by classifying various natural environments into groups that exhibit similar properties. For example, the land usage is consisted from cultivated lands, forests, uncultivated lands, urban area, river, and lake, and then they can easily be linked with each other. Each land usage has its own inside model which is composed of dynamic and static compartments. The functionality of MOGRA has been verified by applying it in the analyses of the migration rates of radioactive substances from the atmosphere to soils and plants and flow rates into the rivers. Migration of radionuclides in combinations of hypothetical various land utilization areas was also verified. The system can analyze the dynamic changes of target radio nuclide's concentrations in each compartment, fluxes from one compartment to another compartment. The code MOGRA has varieties of databases, which is called MOGRA-DB. This additional code MOGRA-DB consists of radionuclides decay chart, distribution coefficients between solid and liquid, transfer factors from soil to plant, transfer coefficients from feed to beef and milk, concentration factors, and age dependent dose conversion factors for many radionuclides. Another additional code MOGRA-MAP can take in graphic map such as JPEG, TIF, BITMAP, and GIF files, and calculate the square measure about the target land. |
