That's what I was thinking... People are curious, and sometimes curiosity overrides the signs of 'DANGER: DO NOT ENTER' plastered all over the place.

What might be a good deterrent? Likely effects of exposure depicted with visual and written descriptions.

Add a little summary on why/how in whatever languages are available for it, medical and molecular diagrams, but only the scientists of the distantly-warned civilization will bother reading up to there.
