This historic 1950 image, provided by the Center for Disease Control and Prevention’s (CDC), National Institute for Occupational Safety and Health (NIOSH), depicted two white coated technicians, who were in the process of conducting radioactive experiments within the confines of a concrete cell, located in Oak Ridge, Tennessee. Not knowing the subject of the experimentation, the danger level was high enough to warrant the execution from behind protected walls, in order to avoid radioactive contamination.
The NIOSH Historic Photo Collection began as the picture file of the Industrial Hygiene Division of the U.S. Public Health Service (USPHS), c. 1930-1960. It is a unique collection of mid-20th Century images of American workers and workplaces and documents occupational safety and health research of that era. The collection consists of approximately 1,000 original photographs and schematic drawings.
