Painted With Poison

They painted glowing dials by hand and were told the radium was harmless. It was destroying them from the inside — and the companies knew.

During and after World War I, young women were hired to paint watch and instrument dials with luminous radium paint. To keep a fine point on the brush, they were taught to wet it with their lips — “lip, dip, paint.” They were told the paint was perfectly safe.

With every brushstroke they swallowed traces of radium. It settled in their bones. Jaws began to crumble — a condition doctors called “radium jaw.” Meanwhile the same companies that called the paint harmless had their own scientists handle radium behind shields and screens.

The scientists wore shields. The girls were told to lick the brush.
