Model evaluation of RIMPUFF within complex terrain using an 41Ar radiological dataset

Leisa L. Dyer, Poul Astrup

Research output: Contribution to journalJournal articleResearchpeer-review


The newly updated atmospheric dispersion model RIMPUFF is evaluated using routine releases of 41Ar from the former HIFAR research reactor located in Sydney, Australia. A large number of 41Ar measurements from a network of environmental gamma detectors are used to evaluate the model under a range of atmospheric stability conditions within the complex terrain area. Model sensitivity of input data is analysed including meteorological station data, land use maps, surface roughness and wind interpolation schemes. Various model evaluation tools are used such as gamma dose rate plots, exploratory data analyses and relevant statistical performance measures. Copyright © 2012 Inderscience Enterprises Ltd.
