Pacific Northwest Laboratory (PNL) has developed the Multimedia Environmental Pollutant Assessment System (MEPAS) to prioritize environmental issues based on their potential impact to public health. MEPAS is an objective, physics-based system that quantifies the relative risk to the surrounding population from radioactive and chemical constituents released to the environment. MEPAS uses generally accepted, independently peer-reviewed computer models that simulate constituent migration and fate from the source through designated transport pathways to important environmental receptors, where exposure and relative risk calculations are performed. PNL has provided support in implementing the MEPAS model by supplying an external code, called a shell, that simplifies model operation and execution. The MEPAS user-friendly shell is a menu-driven application written for IBM PC/compatible systems to provide simplified data input, access, modification, and preparation of site data required to estimate potential environmental hazards using MEPAS. 3 figs.
