X-rays were discovered in 1895, closely followed in 1898 by the discovery of the radioactive properties of radium. Almost immediately, a flood of medical products were introduced, marketed, and purported to cure just about any ailment that existed. For the consumer market, companies and products were branded with terms related to radiation, because it was believed not only that radiation produced positive effects, but also that such branding increased sales. Various forms of radiation sources were added to drinking water, elixirs, lipstick, suppositories, jock straps, and toothpaste, to name only a few. Curiously, even products that contained no source of radiation whatsoever-eg, soap, whiskey, golf balls, playing cards-were marketed with names that contained the words x-rays, radium, or radiation. This was done simply because the belief that radiation was good for you was so strong that such advertising, although false, was effective in driving sales. Even the comic book hero Superman, the champion of truth, justice, and the American Way, used his superpower of x-ray vision in a positive way to fight crime.
