The Radiological Assessment System for Consequence AnaLysis, Version 2.0 (RASCAL 2.0) has been developed for use during response to radiological emergencies. The system supplements assessments based on plant conditions and quick estimates based on paper methods. The model is designed to provide a rough comparison to EPA Protective Action Guidance and thresholds for acute health effects. RASCAL will be used by NRC personnel who report to the site of a nuclear accident to conduct an independent evaluation of dose and consequence projections. The model was developed to allow consideration of the dominant aspects of source term, transport, dose, and consequences. Graphics were designed for use on the COMPAQ Portable III microcomputer used by the NRC response personnel. The model can be run on any DOS system, and the results can be displayed as text or maps. Substantial revisions to RASCAL 1.3 have required the release of this new version of the system. Two new models have been added to RASCAL 2.0. The first, FM-DOSE, computes doses from environmental concentrations. The second, DECAY, computes radiologic decay and ingrowth over a selected time period. The model that previously was the whole of RASCAL has been renamed ST-DOSE. Source term, transport, and dose calculations in ST-DOSE have all been modified, and the input and output screens have been revised based on user comments and suggestions. RASCAL is reviewed on an ongoing basis and will be further revised to reflect advances in our understanding of reactor accidents. This volume is a user`s guide to RASCAL 2.0 and includes complete instructions for its use and example problems. It includes only that technical background material that cannot be found elsewhere. References to the technical details are included.
