US Radium employed hundreds of women at their factory in Orange, New Jersey, including Grace Fryer. Few companies at that time were willing to employ women, and the pay was much higher than most alternatives, so the company had little trouble finding employees to occupy the rows and rows of desks. They were required to paint delicate lines with fine-tipped brushes, applying the Undark to the tiny numbers and indicator hands of wristwatches. After a few strokes a brush tended to lose its shape, so the women's managers encouraged them to use their lips and tongues to keep the tips of the camel hair brushes sharp and clean. The glowing paint was completely flavorless, and the supervisors assured them that rosy cheeks would be the only physical side effect to swallowing the radium-laced pigment. Cause for concern was further reduced by the fact that radium was being marketed as a medical elixir for treating all manner of ailments.
