Risk vs Perception of Risk

Back in March, in the days after the nuclear accident, there was panicked talk of evacuating Tokyo.

Well, risk is a funny thing.  It is quite extraordinary that we are allowed to live in large cities, with the associated vehicle emissions and other pollutions, shortening our lives by a very measureable amount.  Given that the radiation levels in Fukushima are far lower than those that could adversely affect human health, it is absolutely clear that there was an argument for evacuating Tokyo.  If the people of Tokyo had been evacuated into the Fukushima evacuation zone, they would be living longer than if they stayed in Tokyo city.
