|Description:||This historic 1950 image, provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH), depicted two men wearing business suites, who were in the process of setting up a display based on information pertinent to the study of atomic energy, and properties associated with radioactivity. This image was published in a 1951, edition of the ”Industrial Hygiene Newsletter”. Judging from the image, which showed a number of blocks of various materials including (Lt. to Rt.) a 12”-thick brick and mortar block, an 8”-thick brick and mortar block, a 9”-thick wood block, an 8”-thick concrete block, a 12”-thick concrete block, and a 1”-thick steel plate, leads one to believe that this was a display depicting how materials withstand the blast of an atomic bomb (see pictures on the wall at right), or how far radiation penetrates various materials of varying thicknesses?|
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.
