From abstract: "A composite ultrasonic unit was developed to indicate the size and location of non-bonded areas and the presence of non-transformed regions in flat uranium fuel elements clad with aluminum. A two-dimensional recorder was developed to yield instantaneous, permanent records of the non-bonded areas on electrosensitive paper. Panel lights indicate the presence of non-transformed regions that have not received proper heat treatment. Defects 1/8" in diameter are consistently detected at an inspection rate of approximately 50 sq. in./min."

From abstract: "There were significant increases in radioactivity in the environs of the Savanna River Plant during the period from January 1954 to July 1954. All of these increases were relatively small as compared to the maximum permissible concentration. Although fallout from Pacific tests was the main contributor to the increased activity, some of the increase was due to normal Plant operations."
