TV researcher Byron Shelley was checking his facts out as he worked on a TV project when he discovered some amazing facts about radium.
He found that radium - a highly toxic radioactive isotope - had been used in an astonishing variety of products. This came as a big surprise to Shelley, not least because you would have expected people to be a little bit suspicious of something that glows in the dark, and makes you feel really ill.
But apparently our ancestors loved the glowing stuff.
People used radium bath-salts in order to bring a healthy glow to their skin, used radium cream on the skin for some obscure reason, brushed their teeth with radium toothpaste, and even smoked radium sodden cigarettes.
"Of course, somebody had the good sense to realise that this was some pretty dangerous stuff they were messing with," Shelley told us. "The radium products were withdrawn from sale. Mind you, I can't help wondering if maybe Simon Cowell somehow got his hands on some of that radium toothpaste."
More as we get it.
