The results of the model run using ANU-CTM with ECMWF wind field data for 1993 are presented in Figures 3 and 4. Figure 3 presents individual concentration estimates at times throughout the year whereas Figure 4, an animation, contains the model results for each day.
Both figures show the concentration of radioactive gas relative to the concentration at the point of release. Air parcel concentrations are considered high when they are close to the original concentration at the point of release near Akkuyu, Turkey and low when they are approaching background levels.
Occasionally high concentrations can remain in air parcels transported over great distances. Eventually the release of a trace gas mixes throughout the global atmosphere while slowly being removed by rain, contact with the land surface, plants and the ocean and through chemical transformations in the atmosphere.
Figure 3 - Shows the air parcel concentrations and risk (high, medium and low) for every 15 days during the one year model run.
