Kudos to the article for not fuelling radiation-related fears!
Slotin died because a stupid, preventable accident, and Plutonium is indeed dangerous. But stupid, preventable accidents happen in many industries and they are just as lethal. I appreciate that the events are well described, but no unnecessary rethoric is added to that.
(I'm still burnt by the amount of gut-wrenching drama they added in Chernobyl)
