United States Radium Corporation

United States Radium Corporation is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand United States Radium Corporation rather than just read about it. In short: The United States Radium Corporation was a company, most notorious for its operations between the years 1917 to 1926 in Orange, New Jersey, in the United States that led to stronger worker protection laws. After initial success in developing a glow-in-the-dark radioactive paint, the company was subject to several lawsuits in the late 1920s in the wake of severe illnesses and deaths of workers (the Radium Girls) who…

Key takeaways

  • United States Radium Corporation belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect United States Radium Corporation to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of United States Radium Corporation from memory before moving on to harder problems.

Reference excerpt

The United States Radium Corporation was a company, most notorious for its operations between the years 1917 to 1926 in Orange, New Jersey, in the United States that led to stronger worker protection laws. After initial success in developing a glow-in-the-dark radioactive paint, the company was subject to several lawsuits in the late 1920s in the wake of severe illnesses and deaths of workers (the Radium Girls) who had ingested radioactive material. The workers had been told that the paint was harmless. During World War I and World War II, the company produced luminous watches and gauges for the United States Army for use by soldiers. U.S. Radium workers, especially women who painted the dials of watches and other instruments with luminous paint, suffered serious radioactive contamination. Lawyer Edward Markley was in charge of defending the company in these cases.

History The company was founded in 1914 in New York City, by Dr. Sabin Arnold von Sochocky and Dr. George S. Willis, as the Radium Luminous Material Corporation. The company produced uranium from carnotite ore and eventually moved into the business of producing radioluminescent paint, and then to the application of that paint. Over the next several years, it opened facilities in Newark, Jersey City, and Orange. In August 1921, von Sochocky was forced from the presidency, and the company was renamed the United States Radium Corporation, Arthur Roeder became the president of the company. In Orange, where radium was extracted from 1917 to 1926, the U.S. Radium facility processed half a ton of ore per day. The ore was obtained from "Undark mines" in Paradox Valley, Colorado and in Utah. A notable employee from 1921 to 1923 was Victor Francis Hess, who would later receive the Nobel Prize in Physics. The company's luminescent paint, marketed as Undark, was a mixture of radium and zinc sulfide, with the radiation causing the sulfide to fluoresce. During World War I, demand for dials, watches, and aircraft instruments painted with Undark surged, and the company expanded operations considerably. The delicate task of painting watch and gauge faces was done mostly by young women, who were instructed to maintain a fine tip on their paintbrushes by licking them. At the time, the dangers of radiation were not well understood. Around 1920, a similar radium dial business, known as the Radium Dial Company, a division of the Standard Chemical Company, opened in Chicago. It soon moved its dial painting operation to Ottawa, Illinois to be closer to its major customer, the Westclox Clock Company. Several workers died, and the health risks associated with radium were allegedly known, but this company continued dial painting operations until 1940.

Worked examples

Example 1 — a first encounter with United States Radium Corporation

Start with the simplest possible case. Write down what United States Radium Corporation claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to United States Radium Corporation before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about United States Radium Corporation ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of United States Radium Corporation

In research
United States Radium Corporation appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses United States Radium Corporation in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
United States Radium Corporation is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1914 establishments in New York City, 1980 disestablishments in New Jersey, American companies disestablished in 1980, so understanding it makes those chapters shorter.
In everyday life
Look for United States Radium Corporation outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
