Experts from the Defense Threat Reduction Agency’s Joint Science and Technology Office and the Edgewood Chemical and Biological Center are getting creative with a new decontamination System Performance Model (SPM).
Led by JSTO’s Mr. Michael Roberts and ECBC’s Dr. Brent Mantooth, the Contact hazard, Residual hazard, Efficacy, Agent, Test and evaluation, Integrated and Variable Environment (CREATIVE) decontamination SPM uses a computer-based modeling approach to simulate processes. These include contamination, decontamination and post-decontamination contact when a chemical or biological agent is present.
Decontamination involves a complex series of interacting processes that contribute to post-decontamination hazards such as vapor emission and contact transfer. Currently, the CREATIVE SPM uses deterministic physics-based models to simulate contamination, decontamination and post-decontamination hazards for a wide range of military materials from traditional and emerging threats.
Each contaminant-material-decontaminant combination is a unique system with substantially different responses. The model parameters are not trivial to determine and most parameters vary with environmental conditions such as temperature, humidity and wind.
