The discovery of radium by Marie and Pierre Curi changed medical history. But while we now use the element with caution, people in the early 20th century didn’t know how harmful it could be. As a result, countless everyday products were made with radium, including toothpaste, makeup and hair dye.

Sadly, many of these women died of cancer caused by the product.
