In 1914 Dr Sabin Von Sochocky discovered the luminous paint formula and founded the Radium Luminous Material Corp (N.Y City) and sold the product under the name “Undark”. Whereas an estimated 4,000 unprotected workers were hired in the U.S & Canada to paint watch faces with Radium. The Chemists with the U.S Radium Corporation used lead screens, masks and tongs. I want to pursue the social, medical and legal consequences for the Dial Painters who unwittingly worked with this dangerous radio luminescent substance Radium, whilst the owners of the factories and their scientists carefully avoided any exposure to themselves. I don’t want to spend much time on the physics of radioactivity, or it’s earlier developers Pierre and Marie Curie (who died of Leukemia in 1898) as time doesn’t permit. Hundreds of women died, suffered life-long illnesses and grotesque disfigurement from their exposure to Radium, which is present only in uranium one. The history of mostly woman dial-painters that created these wonderful luminescent dials is one of huge tragedy, deceit and arrogance by large corporations. This was a glow of a luminous paint formula which included Radium, a radio-active substance. In regards to the 7 displayed, death and disability has always lurked in both the painted hands and numerals.Īs a boy I can remember snuggling under the blankets in my dark bedroom and marveling at the beautiful greenish glow of my wristwatch. I have a long held passion for collecting watches and clocks, some of which I have brought along this evening. ![]() This is the transcript of a talk that Terry gave to the Auckland Medical History Society on 2nd August 2007. ![]()
