Here's a scan of a page of an Italian comics superhero, Misterix. He says: "There's no fear of radium anymore. / Leave the girl alone!"
Here's some info on Misterix in English - it's not much, but all the other pages Google finds are in Italian which I don't speak very fluently, I must say. This seems a good place to start, though. The comic strip was published in Finland in the fifties in the Seikkailukertomuksia/Adventure Stories magazine that was one of the Ilmarinen publishing house's fictionmags focused on crime and adventure. They had lots of comic strips, this being some of the weirdest.
