Figure 4: 
Calculated annual radiation 
doses for individuals in the 
Baltic Sea region consuming 
9 kg/y of fish flesh. The 
graphs show the same data, 
but the graph on the top 
uses a logarithmic scale 
on its vertical axis. The six 
radionuclides shown are those 
with the largest contributions 
to the dose; the sum of the 
radionuclide contributions is 
shown as “total".
