Simple mistake? Or...
Of course it's a mistake! Simple maths says it should be 18.

In http://qi.com/infocloud/bananas, the "Radioactive 'nanas" entry states:

Quote:
...you get a dose of about 0.005 millirem from eating a banana. Living within 50 miles of a nuclear power plant exposes you to an average annual dose of 0.09 millirem per year, i.e. the same as eating 1.64 bananas.


Is this a simple arithmetic mistake? It's not a shifted decimal point, and the best I can figure is that the obvious answer "18 bananas in a year" doesn't account for accumulation in the body or something. So should that be "1.64 bananas a month"? Something else?

Yes it looks like a simple mistake. Any of those numbers could be incorrect and we don't know how the calculations were made. We also don't know WHICH nuclear power plant and when the readings were taken. So in all, with so many possible permutations and variables, such a statement is practically nonsense!
