Bananas are (slightly) radioactive. The banana equivalent dose (BED) is a measurement of radiation. It’s definitely not enough to hurt you.
When we think about risk, the BED is a useful way to find perspective. Is the exposure this new thing will cause on the order of a banana? If so, perhaps we shouldn’t worry about it so much. A chest x ray might be like eating 100 bananas… it gives us a scale we can work with.
Driving a car is far more dangerous than being on an airplane. The Honda Civic dose might be a helpful way to think about the risk of a crash.
And far more people are injured or killed in collisions with deer and moose compared to sharks. The Moose equivalent dose for exposure to wild animals might be worth considering.
Finally, and most salient, the chances that you will experience significant long-term damage from wearing the wrong color shoes to fourth grade, or by asking a dumb question after a presentation are lower than being injured by a pumpkin. And just imagining the pumpkin equivalent dose makes it hard to take ourselves too seriously.
