Although this interesting chart made for the rest of us, can seem to be complicated at first sight, you should give it a try. It’s actually very easy to understand. Just start reading on top left at the blue squares, then to the greens on top right and then the red ones. It’s giving us a very good idea of how much radiation is coming from everything, from a banana to a nuclear reactor meltdown. Thanks to Randall Munroe & co, this can serve the health of humanity.
