Did You Know?
Clarence Madison Dally an employee of Thomas Edison at his West Orange research labs volunteered to work on the newly discovered x-rays. Using a fluoroscope, made of a fluoride gas filled light and two pieces of cardboard to focus the x-rays, Dally would expose himself to high concentrations of radiation eventually leading to radiation poisoning. After Dally’s death when Edison was asked about x-rays he would respond with “Don’t ask me about x-rays. I am afraid of them.”
