A Blue-Green Glow in Orange, New Jersey

In the early 1920s, walking around Orange, New Jersey at night, you might have seen young women coming out of a factory, with hair, skin and clothes softly glowing in the dark. Some called them “ghost girls.” Newspapers would later call them “radium girls” because the glow on these women came from radium-based paint that they used to make glow-in-the-dark watches for the US Radium Corporation. They thought it was perfectly safe to work with radium, maybe even healthy. They’d soon find out it wasn’t.
