Re: That dirty yard in the neighbourhood
That's kind of hilarious how blase they were about radioactivity back in the day. Even though the dangers are way overhyped (as the queen surviving just fine for 61 years since that demonstrates) I imagine if William and Kate wanted to pick up a hunk of plutonium to see if it was warm their security would quickly disabuse them of that idea.
The big problem with plutonium is inhaling it, if it would be made airborne and spread out. It'll stay in your tissues and cause problems - sort of like if instead of just picking up a hunk of it the queen was given a necklace made of it. I doubt she would have been cancer-free having plutonium against her neck since 1957.
