As for instance half of Sweden still have increased levels of caesium 137 since Chernobyl, and I have just finished a spaghetti bolognese made from a moose from that area, I am not really impressed by average values.

The health effects have been small in Sweden, but it still affects our quality of life, in the sense that we have to be vary of what we eat.

If we keep having an incident every 15-20 years, it will potentially affect large areas, and another incident in Europe might be unfathomably expensive.
