Oh ok, as long as they CAREFULLY examined the liquid’s appearance and color before opening it up and drinking it. Some people will drink almost anything put in front of them. Did anyone even consider what else there could be in that bottle other than ethyl alcohol? Substances and chemicals 150 years ago that no one imagined could be poisons, contaminates or carcinogens, much less radioactive?
Unless you are deliberately trying to concentrate (natural) radionuclides, there's little chance of your inadvertently doing so.
And radioactivity wasn't discovered until 1895.
