Banana equivalent dose

Today I learned that the “banana equivalent dose” is a way of comparing the relative level of radiation exposure of different activities. For example, a dental x-ray is the equivalent of eating 50 bananas. A transatlantic flight is like eating 800 bananas.

A lethal dose of radiation is equivalent to 35 million bananas. Which is funny, because it only takes consuming about 200 bananas to die of potassium poisoning.

The video is enjoyable, and (spoiler) it also happens to be a performance of 4’33”, so you get a two-for-one. You’re welcome.
