I have never heard this brought up when a Nuclear reactor disaster happens, so I will ask it here. With the fear of radiation spreading due to a failed reactor, wouldn't animals spread the radiation? It's kind of hard to keep birds out of the area, especially near old disasters like 3 mile island and Chernobyl. Not to mention deer, foxes, game birds and other smaller animals like rodents and insects. Seems to me then these animals could come in contact with human populations or even be eaten by us and thus spreading the radiation to more populated areas. Any thoughts?
