Radioluminescence, the process by which light is produced by bombarding a reactive material with ionizing radiation, was widely used as the demand for watches that were readable at night grew. At the November 2017 meeting of the Horological Society of New York, Kathleen McGivney will discuss the history of luminescence in watches and instrument dials. In her talk, McGivney will visit the beginning of the use of radioactive material in watch and instrument dials, the reason for the use of radium as the specific material to achieve that goal, the context of the prevailing wisdom of the day of the safety of radium, and how and why watch manufacturers moved on to other materials to achieve luminescence. McGivney will also discuss the implications of radium dials that still retain some radioactivity to collectors and watchmakers who handle them.
