Radiation in Tokyo Same as Eating 1.5 Bananas

A bit more on perspective. 

    First, here is a link to a map of a few dozen independent radiation monitoring stations. You can click to see the radiation measurements in real time.

    Second, back in school we talked about the "Banana Equivalent Dose."  You see, bananas contain a lot of potassium, and a certain amount of the Earth's potassium is slightly radioactive.  Eating a banana will expose you to about 0.1 microSv. Currently radiation levels in Tokyo are about the same exposure as eating 1.5 bananas. 



    I don't want to make light of the seriousness of the situation, but there is no radiation danger for those of us in Tokyo.

Is there radioactive caesium and strontium in bananas?

That's no ordinary banana!

JT: there is naturally radioactive potassium-40 in bananas, which by anti-nuclear propaganda standards of half-life should be more scary than caesium and strontium!

Natural potassium-40 has a half-life of 1,248,000,000 years, compared to only about 30 years for strontium and caesium!
