Dreams of Falling

I've always thought that about The Naked Time. Scientists certainly 'knew better' in the 1960s: germ theory and radiation poisoning were known, the amount of work that went into making space suits was a thing... microscopes were everyday even in schools, so of course adequate safety gear and its precautions were a thing. I suspect the obviousness of that fail was mainly to make sure the whole tv audience could follow it - that kind of incident in literary SF would have been a tiny bit subtler most of the time.

But on the other hand we know the statistics about doctors washing their hands, so... it's also maybe not that unrealistic as a brain fail (although the safety gear being that easy to take off and the dude being that unsupervised with it in that situation maybe is).
