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.

Sure, stuff like Radithor came later but you didn’t need to discover radiation to think that someone might add uranium or radium, which still existed in some form, to a drink because they thought it improved its flavor. Maybe it leached out of the bottle glass, put there to add color. They used whatever they found to make stuff and had no idea about the toxicity—going back to the Romans who put lead acetate into wine and food to sweeten them.
