Forecasting Exposures Using Well Mixed Room Models - Part 1 Live Virtual PDC


The new one and two-box Well Mixed Room (WMR) models will be introduced. TEAS-Student (a student version of Task Exposure Assessment Simulator; Windows only) will be provided. Constant emission and decreasing emission models will be covered. Deterministic and probabilistic modeling methods will be used to calculate single exposures or full-shift exposure profiles. A systematic approach to calibrating a WMR model will be introduced, along with the standard generation rate algorithms. Participants are encouraged to bring modeling examples. This PDC course will concentrate on the practical application of WMR models.
