The Austrian Institute for Meteorology and Geodynamics (ZentralAnstalt für Meteorologie und Geodynamik – ZAMG) continues to provide updated versions of animated radiation dispersal modeling simulations, like the one above.
The animation was originally produced and used by the CTBTO’s International Data Centre as a model to forecast the radiation dispersal pattern to be expected in the period 6-8 April. It does not depict the actual findings and measurements of the CTBTO radionuclide stations.

The graph below depicts the levels of atmospheric concentration of Iodine-131 in becquerels per cubic meter of air. These levels were measured by nine certified radionuclide stations of the CTBTO’s International Monitoring System on a daily basis from 16 March to 3 April.
It was made public by the Federal Office for Radiation Protection of Germany (Bundesamt für Strahlenschutz, BfS), which continues to provide on-line updates on information originating from the CTBTO’s daily supply of data and analyses.
