Worker Exploitation at Radium Dial

By Samantha Wilcoxson for Silver Dagger Book Tours

June 2025 – Luminous Blog Tour

Worker exploitation by Radium Dial is the subject of my newest novel, Luminous, which tells the story of Catherine Donohue, one of hundreds of young women who worked as dial painters in the 1920s and 1930s. Her struggle to have her illness recognized as radium poisoning and to have Radium Dial held responsible will stir up the emotions of any reader. The battle she fought helped to change workers’ compensation laws so that others would not suffer her fate. Although Catherine never dreamed of being a heroine, she changed the course of history.

Radium Dial opened in Ottawa, Illinois in 1918 in response to the demand after World War I for glow-in-the-dark watches and instrument dials. The location was an old, brick school building with large rooms and big windows perfect for the painting work. Radium Dial provided many working class women with higher paying jobs than they could obtain elsewhere.

Catherine Donohue was one of those women. She began working at Radium Dial in 1922 at age 19. She and several of her coworkers soon began suffering symptoms of radium poisoning and fought for years to have their conditions recognized and covered by workers’ compensation legislation. Radium Dial continued operating and denied that they owed anything to the women they had slowly poisoned over their years of employment.

In 1936, Radium Dial closed their operations in the old high school and moved into a new building just a few blocks away. This new company was called Luminous Processes. It utilized much of Radium Dial’s assets and hired the same employees. The move was a strategy to protect corporate assets from the lawsuits of former employees. When Catherine’s case was heard before the Illinois Industrial Commission, only $10,000 was available to be paid out to the several families suffering from radium poisoning.

Operating under the name of Luminous Processes, Radium Dial protected millions of dollars in profits from those employed before 1937, but that isn’t the worst of it. They sold the old school to a meat packaging company, which experienced an exceptionally high rate of cancer in its employees and customers. When the building was demolished in 1968, the rubble was used as fill all around Ottawa, poisoning residents for decades.

At the new Luminous Processes building, employees continued to use radium without proper caution, also adding to the town’s high rates of cancer and other diseases. Sick workers were offered $100 each in severance pay to keep them from seeking legal action that they could ill-afford anyway. Luminous Processes operated until 1978. The company paid only $62,000 toward the millions of dollars of cleanup that is ongoing to this day by the Environmental Protection Agency.

EXCERPT

It was not until they broke for lunch that Catherine had the opportunity to tell Peg that she had brought enough to share.

“That’s too kind of you, Catherine, but I couldn’t take advantage.”

“You wouldn’t be,” Catherine insisted, thrusting the sandwich into Peg’s hands.

“You don’t understand.”

Peg’s voice was quiet, her words oddly slurred. Catherine realized that she hadn’t heard Peg speak much lately.

“Then help me understand.” Catherine placed her hands on Peg’s shoulders, gently but firmly. “Tell me what is wrong. Let me help you.”

Peg sighed and gave in, gesturing for Catherine to follow her into the tiny bathroom shared by all the dial painters. Once they were snugly closed inside, Catherine examined Peg’s face and saw her own concern mirrored there.

Peg surprised her by not speaking. Instead, she opened her mouth wide and pulled at the side of her mouth for Catherine to see inside.

“Oh, Peg! How in the world?”

“They just fell out,” Peg whispered.

Having seen the inside of Peg’s mouth, understanding flowed over Catherine. Her friend wasn’t avoiding food and conversation because of money problems. She must be in constant pain from the throbbing, angry abscesses that flared irritably where two of Peg’s teeth should have been.

“You poor thing!” Catherine wrapped her arms around Peg, which was easy to do in their close quarters. Peg’s shoulder blades and ribs felt sharp. “How long have you been suffering?”

Peg only shook her head as her tears began to fall.

“Oh, shush, love,” Catherine murmured, swaying slightly on her feet. “We will talk about it when you’re ready, and we will find you help.”

“That’s just it,” Peg suddenly cried out. “I’ve been to the dentist. He doesn’t know what could be wrong, and four more of my teeth are loose.”

“Four?” Catherine’s voice was scarcely more than a whisper, and she felt a sliver of fear pierce her heart. What could be wrong?
