Factory managers instructed female dial painters to point their radium-paint-laden brushes on their lips to maintain a fine tip, claiming the paint was harmless. This practice was preferred over rags or water rinses because it saved time and material, despite the paint containing deadly powdered radium mixed with zinc sulfide, gum arabic, and water.
Beginning around 1917 in Orange, New Jersey, and later at factories in Ottawa, Illinois, and Waterbury, Connecticut, female workers known as the Radium Girls repeatedly ingested radium while painting self-luminous watch dials and hands. Over time, many developed severe radiation poisoning, resulting in illness and death across all three facilities.
The deaths and illnesses of the Radium Girls led to numerous lawsuits against the factory owners, drawing public attention to occupational radiation hazards. Their cases produced significant reforms to labor laws in both the United States and Europe, establishing stronger protections for workers against toxic workplace exposures and influencing the development of occupational health standards.
