The documentation of the APEX model is currently divided into two volumes. Volume I: Users Guide (this document) is designed to be a hands-on guide to the model. It focuses on how to run the APEX computer model, develop the appropriate input files, and understand the model output files. Volume II: Technical Support Document describes the scientific basis of the APEX model and provides scientific background for the model algorithms. It covers the methods implemented in APEX for calculating microenvironmental concentrations, modeling ventilation, estimating dose, and assembling activity diaries.
