Inspired by a risk conference I attended, I decided to try my hand at visual demonstrations of toxicological safety limits and pesticide exposures. It struck me that the same kind of visualisation might work well for a demonstrating radiation dosages. I have written earlier about Radiation and Cancer Risk, after I visited Switzerland’s interim repository for nuclear waste, ZWILAG. While in the heart of the place – the dry cask storage hall which houses the spent nuclear fuel – we crossed a line with a sign that read: “HIGH RADIATION AREA No unnecessary stay !!!”
This left me curious. I wanted to know how dangerous a “high radiation area” was, and after a dive into the evidence, I got my answer. But much of what I wrote there could also be effectively summarised with an infographic.
I had the privilege of giving a public presentation at a large Finnish political discussion and debate fair
