The symbol was first ‘doodled’ by members of a research group headed by Nels Garden, who wrote in a letter that the symbol “would best symbolize the degree of hazard, type of activity, etc., but which was simple in design”.

Is nuclear waste actually green?

The radioactive byproducts of nuclear reactions remain inside the fuel. No green goo anywhere. There is not that much of it. All of the used fuel ever produced by the commercial nuclear industry since the late 1950s would cover a football field to a depth of less than 10 yards.
