Fig. 6.5 Example for radioactivity release after a core melt accident with major release of
radioactivity. The different colors indicate areas where the population would have to be evacuated
or remain in shelters [ 17 ]
Figure 6.5 shows by way of example the spread of radioactivity released after a
core melt accident into the environment. The release of radioactivity as a function
of time (noble gases, iodine, aerosols), the wind speed and wind directions are
assumed for this example. The different colors indicate areas where evacuation or
sheltering of the population would be required.

6.5 Protection and Countermeasures
Radioactive exposure of the population can be affected by these protective mea-
sures and countermeasures:
- sheltering in buildings and protective rooms,
- evacuation of the population,
- distribution of iodine tablets,
