In that same experiment, Drinker and Castle mentioned how the dial-painters and their facilities were
coated in radium dust:
“The hair, faces, hands, arms, necks, the dresses, the underclothes, even the corsets, of the dial painters were luminous. One of the girls showed luminous spots on her legs and thighs. The back of another was luminous almost to her waist. Dust from the machine shop below the painting room was luminous, and the same property was exhibited by office girls and by others about the plant not employed in the paint room.” (Drinker, Cecil K., et al. "Necrosis of the Jaw in Workers Employed in Applying a Luminous Paint Containing Radium.")
