ADMSSTAR is a model for the analysis of Short-Term Accidental Releases based on the ADMS methodology. ADMSSTAR has been developed specifically to estimate air concentration and deposition rate for radiological or chemical emissions to the atmosphere.|
ADMSSTAR can be used either in situations where the source details are known or it can perform a back calculation and estimate the source strength based on sample data. In both cases ADMSSTAR will calculate air concentrations and deposition rates. These can be compared against regulatory or other levels (e.g. EU maximum permitted levels in foodstuffs). ADMSSTAR may be linked with ESRI's ArcGIS (Geographical Information System) and used to display contours of concentration and/or deposition overlaid on a map of the area where the incident occurred.
ADMSSTAR is underdevelopment to use a Lagrangian puff methodology to enable complex terrain along with temporally and spatially varying meteorology to be incorporated into the model.
