Highlights magazine. Now THAT goes back a LONG time. Yes, somewhere in my mind I am hazily aware that Polonium was named after Poland, but I did forget that the Curies discovered it. From what I read though, I didn't have the feeling that the cigarette makers put it in there on purpose. Somehow it's just there. They do, however, (and have for some time) have the means to take it OUT, which they haven't done. Which to me is kind of gross. Thanks for your comment! Take care.
