United States Radium Corporation
Established in 1914 in New York City by Dr. Sabin Arnold von Sochocky and Dr. George S. Willis, the United States Radium Corporation was a privately held enterprise focused on manufacturing luminous radioactive paint. This paint was chiefly applied to watches and instrument gauges used by the U.S. military during both World Wars. The company’s main operations were based in Orange, New Jersey, with its peak activity spanning from 1917 to 1926.
Although initially successful commercially, the corporation became infamous due to serious health complications among its workforce—particularly female dial painters—caused by radioactive exposure. These incidents, which came to be known as the plight of the "Radium Girls," led to landmark legal actions in the late 1920s and prompted significant reforms in occupational safety regulations. The company’s defense was managed by attorney Edward Markley.
The United States Radium Corporation expanded through various subsidiaries, including Safety Light Corporation, USR Chemical Products, USR Lighting, USR Metals, and U.S. Natural Resources. The firm ultimately discontinued operations in 1970 and was integrated into Safety Light Corporation during the period from 1982 to 2007. Its former manufacturing facility in Orange was later designated a Superfund location due to contamination with radium isotopes and heavy metals.
This case remains a pivotal example of industrial risk management shortcomings affecting corporate reputation, regulatory policies, and legal accountability within the radioactive materials sector.
History
Initially founded as the Radium Luminous Material Corporation in 1914 by Dr. Sabin Arnold von Sochocky and Dr. George S. Willis in New York City, the company first extracted uranium from carnotite ore before moving into producing radioluminescent paint and related products. Production sites were set up in Newark, Jersey City, and Orange, New Jersey. In 1921, leadership changed hands when Arthur Roeder succeeded von Sochocky as president, coinciding with the company’s rebranding to United States Radium Corporation. The Orange facility processed approximately half a ton of ore daily, sourced primarily from mines located in Colorado and Utah.
Among its early personnel was Nobel Prize winner Victor Francis Hess (1921–1923). The company’s signature product, Undark, a luminescent paint combining radium and zinc sulfide, experienced heightened demand during World War I for use on watch dials and aircraft instruments. The painting work was mainly carried out by young women who were instructed to shape their brushes by licking them—unaware that this practice caused ingestion of radioactive substances.
Though awareness of radiation dangers grew during the 1920s, protective equipment was supplied solely to scientific staff rather than to production workers. This neglect resulted in severe health conditions such as radium jaw among dial painters and sparked prominent litigation initiated by the "Radium Girls" beginning in 1925. Manual dial painting was discontinued only in 1947.
Following World War I, military orders declined while competition increased due to new ore deposits discovered in Katanga Province. By 1927, operations were consolidated into Manhattan offices and the Orange plant was leased out. The onset of World War II revived demand for luminescent materials; by 1944, U.S. Radium operated multiple facilities across Pennsylvania, New Jersey, California, and New York City. The company also participated in psychological warfare initiatives during this period.
After World War II, the adoption of promethium-147 and tritium for luminous applications alongside the cessation of Canadian radium mining in 1954 raised supply costs. Operations were centralized in Morristown, New Jersey, and Bloomsburg, Pennsylvania—producing watch dials and instrument gauges utilizing radium and other radioactive elements. Radium processing activities ended in 1968 when these operations were spun off into Nuclear Radiation Development Corporation.
In 1969, a new facility opened in Bloomsburg focusing on manufacturing tritiated metal foils and self-luminous tubes employing tritium illumination technology. Starting in 1979, U.S. Radium underwent significant restructuring: assets were transferred to Metreal, Inc., with production shifted to subsidiaries including Safety Light Corporation and USR Lighting. In 1980, USR Industries was formed as a holding company consolidating U.S. Radium’s interests.
Safety Light Corporation became an independent company in 1982; its tritium-illuminated signage products were marketed under the Isolite brand through a specialized subsidiary.
In 2005, the Nuclear Regulatory Commission chose not to renew licenses for the Bloomsburg site; subsequently, the Environmental Protection Agency designated it as a Superfund cleanup site. All tritium-related manufacturing ceased by late 2007.
Immediate aftermath
In 1925, Harrison Stanford Martland, MD, the chief medical examiner of Essex County, determined that the ingestion of radium was responsible for bone diseases, aplastic anemia, and fatalities among the workforce. These health issues and ensuing legal actions prompted the shutdown of the company’s Orange plant in 1927. Although an out-of-court settlement was reached in 1928, numerous claimants had already endured severe radiation-induced conditions or had passed away. The corporation faced allegations of postponing settlements, which allegedly led to additional deaths.
Dr. Sabin A. von Sochocky, who developed the radium-based luminous paint, succumbed to aplastic anemia in November 1928 due to radioactive exposure—underscoring the grave dangers posed by the substance. The contamination from radiation was so extensive that it remained traceable at the burial sites of victims many years afterward.
Superfund site
The facility processed roughly 1,000 pounds of ore each day, resulting in substantial amounts of radioactive waste being discarded onsite. With approximately 1,600 tons of contaminated debris present, the location was classified as a Superfund site by the United States Environmental Protection Agency (EPA) in 1983. From 1997 through 2005, the EPA undertook a comprehensive cleanup involving the excavation and removal of radium-polluted soil from both the factory grounds and about 250 nearby residential and commercial properties.
The EPA finalized its extensive remediation project in 2009, marking a crucial milestone in mitigating environmental hazards and public health threats linked to the company’s past activities.
