Series Description: This series consists of 8x10 inch black and white photographs depicting steps in the processing of radioactive isotopes. The photographs show the use of remote control equipment, the interior of a hot cell, withdrawal of samples from shielded cells, packaging in lead containers, and monitoring activities for radioactivity. The photos are in no particular order and are intermixed with other photos of Oak Ridge and the Hanford Engineer Works in Washington state. The photographs are not dated. Captions are on the back of the photographs. Although carbon-14 is the only radioisotope specifically mentioned in the captions, the photos provide a visual perspective on radioisotope processing procedures.

HAI inventoried these records at the National Archives in Washington, DC, in May 1994, but since then they have been moved to the National Archives at College Park, MD.

Data Elements: 81, 88-89, 117
