When the bomb falls!

I found this online, It is a record telling you what to do when the bomb falls!
This kind of stuff is funny to me and represents a bygone age that I think is weird. People weren't laughing then and were obviously scared though.
This might have given people some kind of sense of security (even if it was false security). I would love to hear it. Especially knowing what I do about radiation exposure which is what my previous job was based on.
(In a medical sense, nothing too diabolical)
