Thousands of legacy radium dials are still owned by the public and the paint can still be dangerous if ingested in sufficient quantities, which is why it has been banned in many countries. Radium paint used zinc sulfide phosphor, usually trace metal doped with an activator , such as copper (for green light), silver (blue-green), and more rarely ...
The people working in the industry who applied the radioactive paint became known as the Radium Girls because many of them became ill and some died from exposure to the radiation emitted by the radium contained within the product. The product was the direct cause of radium jaw in the dial painters. Undark was also available as a kit for general ...
The workers had been told that the paint was harmless. [1] During World War I and World War II, the company produced luminous watches and gauges for the United States Army for use by soldiers. [2] U.S. Radium workers, especially women who painted the dials of watches and other instruments with luminous paint, suffered serious radioactive ...
November 1917 ad for an Ingersoll "Radiolite" watch, one of the first watches mass marketed in the USA featuring a radium-illuminated dial. Radium was discovered by Marie and Pierre Curie in 1898 [1] and was soon combined with paint to make luminescent paint, which was applied to clocks, airplane instruments, and the like, to be able to read them in the dark.
The luminous paint used on the dials contained a mixture of zinc sulfide activated with silver, and powdered radium, a product that the Radium Dial Company named Luma. However, unlike the US Radium Corporation, Radium Dial Company was specifically set up to only paint dials, and no other radium processing took place at the premises.
Radium dial painters were instructed in proper safety precautions and provided with protective gear; in particular, they no longer shaped paint brushes by lip and avoided ingesting or breathing the paint. Radium paint was still used in dials as late as the 1970s. [27] The last factory manufacturing radium paint shut down in 1978. [28]
Radium was used in luminous paint until the 1960s, when it was replaced with the other radioisotopes mentioned above due to health concerns. [1] In addition to alpha and beta particles , radium emits penetrating gamma rays , which can pass through the metal and glass of a watch dial, and skin.
Tritium is not the only material that can be used for self-powered lighting. Radium was used to make self-luminous paint from the early 20th century to about 1970. Promethium briefly replaced radium as a radiation source. Tritium is the only radiation source used in radioluminescent light sources today due to its low radiological toxicity and ...
